CNC aluminum prototype with light sandblasted finishing

Why Is CNC Aluminum Prototype Widely Used?

/in /by

Aluminum is one of the most common material options for CNC machining and prototyping due to its attractive physical properties. The metal is reliable, making it suitable for mechanical components, and the oxidized outer layer of Aluminum is resistant to corrosion by the elements. Unlike many other metals with comparable chemical properties, aluminum provides outstanding machinability: It can successfully penetrate many of its grades by cutting equipment, chipping quickly, and being relatively easy to mold. Aluminum can also be machined more than three times faster than iron or steel.

Here we will discuss some of the critical benefits of CNC Aluminum Prototype and why it is one of the most common prototyping and manufacturing processes, along with some alternatives for aluminum.

 What are the benefits of CNC Machining for Prototyping?

 CNC machining has a range of benefits over 3D printing and other prototyping methods discussed in this article and some drawbacks. One of the main advantages of using CNC machining to make prototypes—Especially for parts finally formed by injection molding—is that CNC machining creates prototypes made of solid materials, unlike 3D printing. It indicates that the CNC machined components’ mechanical properties are very similar to those of the injection molded parts.

It can produce CNC machined parts designs with outstanding surface finishes. Depending on the material chosen and depending on the post-processing processes used, It may leave CNC machine sections as machined, beaded, anodized, powder-coated, sanded with varying grits down to a polished surface, or chrome-plated.

So, why CNC Aluminum Prototype is widely used?

 Here are some of the reason why CNC Aluminum Prototype is used :

 Custom Finishing

 Aluminum can be mold to suit the customer’s needs after finishing. You can make it seem like the most beautiful tradition by doing specific stuff. Aluminum CNC pieces can get plated with different colors as per the specifications. Three of the colors you can try are purple, blue, and green.

CNC aluminum machining is subject to various improvements, particularly in the design and requirements, which allow it to make a quick transition by beginning a newly reviewed and accepted program.

 Machinability

One of the critical reasons why engineers prefer aluminum for their machined components is because, very literally, the material is easy to machine. Although Aluminum CNC Machining would benefit the part’s equipment maker, it also has significant advantages for the corporation buying the piece and the end-user who would purchase it.

Since aluminum chips are simple and easy to mold, they can be cut easily and precisely using CNC machine tools. It has some significant consequences: firstly, the machining job’s short timeframe makes the operation easier (because the machine and less running time need less energy from the device itself). Secondly, good machinability means less deformation of the component as the cutting tool moves through the workpiece.

 Electrical conductivity

Pure aluminum metal has an electrical conductivity of approximately 37.7 million siemens per meter at normal room temperature. Aluminum alloys can have lower conductivity, but aluminum materials are considerably more conductive than other stainless steel alternatives. Due to their electrical conductivity, parts after Aluminum CNC Machining can be used for creating electrical components.

Easy Machining

 The other positive thing about the Aluminum prototype is that products can get conveniently created by punching, folding, and drilling. You may use it to shape the different shapes of the parts as required. The power used in the machining of aluminum is much smaller than that used in steel.

 Anodization potential

Machined aluminum parts are widespread in the consumer electronics industry, not only because of the strength and weight requirements but also because of essential esthetic considerations. As well as being receptive to paints and stains, you can treat aluminum with anodization to thicken the protective outer layer of the Aluminum.

Easily Bendable

 One positive thing about using the CNC machining process for manufacturing aluminum CNC parts is to bend them quickly. In comparison to steel, the machine can rapidly turn the aluminum material during the machining process. The thickness of this material can allow proper use of the different molding methods. The easiest way to do this is by pressing and grinding several shapes of aluminum CNC pieces quickly.

 Alternatives to aluminum in CNC machining

Businesses may, for any variety of reasons, pursue alternatives to aluminum for CNC machining. Overall, the metal has a few weaknesses: the oxide coating will destroy tooling and is typically more costly than substitutes such as steel, partially due to aluminum manufacturing’s high energy costs. Here are several possible machining alternatives to aluminum, focusing on their distinctions and similarity to common silver-gray metals.

  • Steel & stainless steel
  • Titanium
  • Magnesium
  • Brass
  • Copper

Thanks to the  CNC  machining, it is now effortless to come up with aluminum parts. The accuracy you get when removing those bits is the key reason many consider CNC Aluminum Prototype.

Die Casting

What You Need To Know For Metal Casting Technology?

/in /by

In the industry, some of metal parts fabrication and prototype with CNC machining technology is a good option, especially for low volume manufacturing order, but once product requirements coming into mass production stage ,then, other better process has to be taken into account in order to save money .

Casting machines ensure the die is fully closed. They are classified according to the amount of clamping force they can apply and, in the case of machines, they can range from 550 to 5700 tones. In the cold room process, the metal is first melted in a separate furnace and transferred to a holding furnace; then it is poured into a filling chamber and injected into the mold.

Die Casting

Advantages of the high pressure Die Casting Technology process

High pressure Die Casting Technology can produce very large alloy parts in high volumes and at high speed. The high-pressure process can also produce thin-walled components and cast parts together with different types of parts, such as screws and liners, which are then an integral part of the product itself.

Application

Cold-chamber high-pressure Die Casting Technology is ideal for the production of a diverse range of aluminum and magnesium parts for the automotive industry, such as engine blocks, gearbox crankcases, oil pans, engine mounts and structural parts like cross beams. It is widely used in other industries to manufacture components for applications ranging from the simplest (a lighting component) to the most demanding (parts for an aerospace engine).

Light pressure Die Casting Technology

Although the ability to reduce physical weight has been a key driver of the increased demand for aluminum and other parts in light alloys in recent years, other properties, such as electrical and thermal conductivity, mechanical strength, corrosion, and strength, they also attract the attention of manufacturers in a multitude of industrial sectors.

Due to this unique range of characteristics, light metal can be used to melt complex safety-critical components in the aerospace, automotive and electronics industries. It also represents a cost-effective production option for simple parts, from lighting components to cookware. Three of the most common technologies for producing light alloy Die Casting Technology are: high pressure casting, gravity casting and low pressure casting. Each technology also supports semi-permanent and chill casting processes.

The main advantage of both permanent and semi-permanent Die Casting is its suitability for process automation and large-scale production, making the techniques popular with high-volume fabricators. Depending on the application, alloy part specifications can vary greatly, from geometric complexity and wall thickness to density and strength of the metal.

Sand mold technology process

In sand mold technology, patterns are used to create the molds, preparing and joining these sand molds is a very important step. Patterns or molds are needed to create the empty cavity within the sand and in this way make the desired part.

Two main methods are used for joining the sand molds:

  • “Green sand” consists of mixtures of sand
  • “Dry sand” is composed of thermally or chemically cured synthetic sand and binders.

Sand Mold consists of pouring molten metal into the mold with the shape of the part or object to be manufactured and waiting for it to harden when it cools. Among the most common foundry metals are cast iron, steel, aluminum alloys and brass.

How does the sand mold work ?

Sand mold is based on the principle of gravity, that is, the only source of energy that forces the metal to fill the mold cavity is the force of gravity. This type of technology is used for pieces in which the quality of finish and dimensional is not decisive. The disadvantages are low dimensional accuracy, poor surface finish, and low strength as a result of slow cooling.

Sand mold will not have as high dimensional accuracy as die casting. In Die Casting, the metal in liquid state is forced into the cavity between the dies by injecting it at high pressure into a die by a special die casting machine, with a closing force of 300 tons. The working pressure is maintained until the metal has completely solidified.

The pieces obtained with this procedure are of high quality in terms of their finish, their dimensions and have great precision. This procedure is one of the most used for the production of large quantities of castings. The mold called matrix, is the most delicate element of die casting, it must be made of steel with great accuracy and cleanliness, which is why precision tools and machines must be used.

Once the matrix is ​​finished, it is subjected to a heat treatment, which increases its hardness and resistance to the attack of liquid metal. In die casting you can control the physical conditions in the solidification of the metal. While the solidification of the metal in a sand mold is carried out under the action of its own weight, leaving pores

5 Axis CNC Machining

The Benefit Of 5-axis CNC Machining Revolution

/in /by

When we think of part machining, we tend to immediately think of the traditional 3-axis machining (radial, axial and tangential) for both machine tools conventional as for machine tools. While it is true that machine tools have facilitated mass production, much more the CNC prototyping than being controlled by computer reduce the times and increase the precision of production, when dealing with the production of complex parts the 3 aforementioned axes previously they become insufficient.

Thus, the so-called “machining centers” arise which allow work in 4 or more degrees of freedom. This is achieved by starting from the 3 original axes (radial, axial and tangential) and make angular movements with respect to them. Of these machining centers, the most common due to their versatility without reaching extreme complexity, are those that perform 5-axis machining. By using these machines it is possible to machine complex parts, lateral and angular surfaces, as well as undercuts that require interpolation in 5 axes simultaneously.

Some other advantages that this type of machines provide are the following:

  • Possibility of working 5 different faces of the piece simultaneously, eliminating the need for changes of fasteners and repositioning, while increasing precision and repeatability
  • Possibility of tools reaching sections of the part that are impossible to reach for conventional machines.
  • Combination of different types of tools simultaneously, such as milling, turning and drilling tools, along with process tools more
  • Specialized as water jet or laser cutting.
  • Ability to work with a variety of materials on the same machine.
  • Saving physical space in the plant.
  • Reduction of unwanted vibrations due to increased dynamic robustness.
  • It should be noted that these machines achieve their work thanks to great technological advances in terms of the software used for its programming, many of these being compatible with the most famous CAD / CAM systems on the market, which allows a
  • Optimized workflow from the design area to the end product.

Among the various chip removal machining technologies that exist, 5-axis machining is one of the most complex. The 5-axis machining centers have the ability to carry out translations through the X, Y, Z axes; and rotations through two other axes A and B that can be carried out by the table or by the machine head, thus making the tool more accessible to the part to be machined.

5 Axis CNC Machining

There are two work cycles within multi-axis machining:

  • Cycle 3 + 2: the fourth and fifth axis remain fixed, they only move in the step of a process to another, while the X, Y, Z axes move simultaneously.
  • Simultaneous 5-axis cycle: the 5 axes move at the same time, thus reducing the machining times and a better finish of the piece.

To carry out the multi-axis CNC machining process, it is necessary to have a CAM programming software. Using this software, a program is created in which the different parameters to be taken into account during the manufacture of the part are configured, such as the definition of the tool paths, speeds and machining advances. Once the program is finished, a code is generated and transmitted to the machine, which will automatically carry out all the previously predefined movements.

Among the main applications of this type of machining are the CNC prototype of parts in the automotive industry, the manufacture of aeronautical components or the machining of molds and high-precision parts. The purpose of using this type of technology is to achieve a better quality finish and increase productivity, that is, to optimize the low volume manufacturing process. For everything detailed above, it has a 5-axis machining center that also has another advantage: high-speed precision machining, with which optical and high-precision finishes are obtained in the manufacture of prototypes.

Regarding of Promising future:

Thanks to the so-called “internet of things” or “Iota” for its acronym in English, it is expected that technological development in the field of 5-axis machining is accelerated. The possibility of connectivity between prototyping and smartphones has already been tested successfully, opening up a large number of possibilities for monitoring production activities and automation of the same. There is also talk of integrations of functionalities such as fingerprint and iris readers, operation interrupt commands and program restart through voice, nanotechnology and Pico technology, among others, which although they sound like science are very close to becoming a reality today . Without a doubt, 5-axis CNC machining is vital in the productive process of rapid prototyping companies today and will continue to be increasingly important by integrating all those functionalities that technological advances may provide.

Will Industry 4.0 Affect CNC Machining Services?

/in /by

The concept of Industry 4.0 was mentioned for the first time at the Hannover fair (fair dedicated to industrial technology) in 2011 with the intention of launching a project that would carry out the conception and development of the smart factory associated with the fourth industrial revolution, a vision of computerized manufacturing with all its interconnected processes making use of the internet of things (IoT), nowadays called the industrial internet of things (IIoT).

It is said that two years later the German government launched this initiative with the idea of ​​coping with the great advances in industrial matters that were taking place in emerging countries such as China, and that by not being able to compete in production costs, the idea was to be able to exceed them in industrial technology and in the ability to custom machined parts products individually. Although, as has been seen, these countries have not been slow in wanting to get on the bandwagon of this fourth industrial revolution once it is launched in Europe and the United States, where by the way the concept of Industry 4.0 or Industrial Intelligence, unlike in Europe, is called Smart Manufacturing or Industrial Internet. The term Industry 4.0 encompasses many concepts and purposes, but the first advances in this area imply the incorporation of greater flexibility and individualization of custom machined parts processes. The automotive industry is a pioneer in the need to implement these flexible and individualized manufacturing processes, and it is where great advances are already being seen in this area because manufacturers have to adapt vehicles to the individual needs of customers of fast and efficient way.

industry4.0

Principles of design

The design principles on which custom machined parts companies and organizations are based to implement Industry 4.0 are the following:

  • Decentralized decisions. Cyber-physical systems have to be able to make decisions for themselves and to carry out their tasks in the most autonomous way possible.
  • People, devices, sensors and custom machining have to be able to communicate with each other. Here the Internet of Things (IO • Technical assistance) plays a very important role. Cyber-physical systems have to offer support and collaboration to humans in all those tasks that are dangerous, produce fatigue, tiredness or are unpleasant. And on the other hand they have to offer help or support that is capable of adding visual information intelligible to humans so that possible problems can be advanced and / or solved in the shortest possible time.
  • Informational transparency. Information systems have to be able to create a virtual copy or “Digital Twin” of the physical world that surrounds them through the data collected through their sensors and other connected devices in their ecosystem.

Challenges of Industry 4.0

It is expected that the new concept of Industry 4.0 associated with the fourth industrial revolution and Cyber-physical Systems, will be able to promote fundamental changes at the same level as the three preceding revolutions. Let us remember that in the first revolution, mechanics moved by the energy generated by water and steam were introduced, in the second, electricity and mass production invented by Henry Ford were introduced, and the third automation and the proliferation of technologies. of the information. If we had to define the most important challenges that companies and organizations that implement Industry 4.0 are going to have to face, they would be the following: The development of software and analysis systems that turn the deluge of data produced by smart factories into useful and valuable information. T).

CNC machining and Industry 4.0

We hear about the 4.0 revolution and the technologies that are going to transform our world as we know it. Robotics, IoT, Big Data, Virtual Reality, Augmented Reality, 3D Printing… are just some of these technologies. But what is not discussed so much is that many of these innovations are based on technologies that are already well established in our industry.This is the case of additive manufacturing or 3D printing, which uses CNC machining technology as one of its fundamental elements.

The abbreviations precision CNC machining correspond to “Computerized Numerical Control”. It is applied to machines that, unlike conventional or manual ones, use a computer to, based on numerical codes assigned to their degrees of freedom, define the movements that must be made, allowing great precision in drawing circles, diagonals or complex three-dimensional figures.

CNC manufacturing services are capable of moving a tool, in up to five degrees of freedom, to obtain complex three-dimensional figures. Once the computer is programmed, the custom machines parts works alone, allowing the operator to dedicate himself to other tasks, with the consequent optimization of the use of personnel.

5G facilities

5G Is Changing Our Life

/in /by

We have been hearing about it for years, both because of the technological revolution that it entails and because of the typical fears that it arouses among those who do not understand it. But after several years in which it seemed that it was not going to arrive, it seems that prototype manufacturing for 5G facilities will definitely begin to take its first steps in 2019, and both operators and mobile manufacturers (Samsung, Huawei, Xiaomi or LG, among others) are doing your first announcements related to your implantation. But there are still those who do not quite understand what all this for 5G facilities is, not even some presidents of great powers, so we are going to explain what about 5G.

What is 5G?

The idea behind this development is to allow you to make a phone call, write as before, and above all, surf the Internet at a much higher speed than the current one. Do you remember how the speed you had a few years ago on your home Wi-Fi was much slower than it is now? Well, this is similar. In fact, since you are making use of your memory, you may still realize how much your connection improved when you began to change the 3G connectivity of your mobile to take advantage of 4G, you started to be able to navigate at much more powerful speeds that allow you see current websites without problems, as this is a new evolutionary leap.

This fifth generation of wireless communications is the one that is going to try to make viewing a website on a mobile phone like opening any other file, with a speed so fast that we should be able to load Ultra HD videos or 3D models almost without blinking. The official standard has already been approved, and it promises to be between 10 and 20 times faster than current mobile connections.

5G facilities

The Development of 5G

The standard exists, the first mobiles to support it have already been presented, and operators such as Vodafone have already announced that they will begin to deploy it. But currently you can’t use it yet, so it remains to be seen if those speed predictions really come true from the start or if they still take a while to arrive.

What we are sure of is that on paper, prototype manufacturing for 5G facilities are an almost essential process to survive the electromagnetic bottleneck that exists in large urban agglomerations today. With more and more connected devices, it is necessary to increase capacity and allow even more to connect to, for example, support an always-connected ecosystem of smart cars or the increasingly developed Internet of Things.

What differences does it have with 4G?

In this table you will see the main differences between 4G, 4G + or LTE, and 5G. The speed will be much faster, so you can download content almost without realizing it. But even more important is the decrease in latency. Latency is the time it takes to transfer a data packet within the network, the time it takes for an action to arrive from the moment you perform it until it is consumed. Currently there are already very low latencies, but 5G facilities promises to lower them to between 1 and 2 milliseconds. Added to the download speeds, this will mean that if you click on a photo that you have in the cloud, it would take the same time to open it on your mobile as if you already had it in its memory.

In any case, and as we have said before, 5G facilities has not yet been implemented. This means that we can theorize or comment on what benefits it can bring, but that we will not definitely know until it is definitely implemented and it begins to be exploited. At the moment we have already seen demonstrations such as tele-assisted surgeries in real time, in which the surgeon performs the interventions from miles away. A good summary of what the jump from 4G to 5G means was given to us a few months ago by the chipmaker Qualcomm. For them, 4G served to connect people between them, and 5G facilities are a new leap that will allow “connecting people with everything that surrounds us”, promoting not only communications, but other sectors such as automotive, medicine, health or households.

The Future Of Artificial Intelligence Impact On Traditional Manufacturing Industry

/in /by

Believe it or not, with artificial intelligence and CNC machining in UYEE company we are facing the first real transformational technology, also including the point of view of people (not corporate). The cause is reduced to a simple fact: until now, technology has been created to be used by human beings, and based on that use, relationships, business, applications and / or solutions for society were developed.

Technological advances are changing the rules of the game for companies. The development of robotics, the internet of things, artificial intelligence (AI) and CNC machining, among many other factors, are forcing companies to adapt to new ways of organizing, new production models and new human resource strategies to do facing this reality that advances at a dizzying pace.

Artificial Intelligence Will Change the CNC Machining Industry

artificial intelligenceAdecco has carried out a study to measure the direct and indirect impact of artificial intelligence in the world of work. The result reflects that, despite the fact that this technology is still in full development, 37% of the human resources directors surveyed believe that artificial intelligence and CNC machining already have a significant relevance, is the present and is a reality at the moment. 48% maintain that the true impact will come soon, in the short-term future, and that you have to be prepared for when that happens.

Thus, we find that this type of technology breaks with this premise: in this case, the AI ​​is the one that feels, understands and acts. In other words, the business layer of a country (the one that generates value and wealth) is being endowed with an autonomous, intelligent capacity, capable of emulating what human strength was doing until now. This new panorama implies an important component of social impact, and therefore we must take into account the control that this type of impact requires.

Four years ago, according to Tech Vision (Accenture), the smart enterprise ranked fourth among the most relevant trends, while three years ago, topics involving AI were ranked as the most relevant. It is not only a technological concept, but also with a large component of social impact, which implies special procedures when dealing with and managing it within the company.

Artificial Intelligence Makes the Improve Productivity Hugely

However, although artificial intelligence and CNC machining are present on everyone’s agenda (managers, C-levels, programs, etc.), what is still not taken into account is the impact of it. The focus is on training artificial intelligence and CNC machining in UYEE company, but since the system emulates what a person does (actuates, understands and makes decisions), it is becoming essential to take the impact into account.

To illustrate the importance of this impact, we can put the case of Ant Financial (part of AliPay), a fintech that has just raised the largest financing for this type of companies globally. This fintech is determining payments, insurance, loans, etc. based on machine learning. As we can see, the relevance of the task has an incredible impact, to the point that a single decision can change the economic situation of a family or business

Why does the case of artificial intelligence and CNC machining require a different management? Apart from what has already been commented, we have to observe three major factors: AIs learn autonomously, make autonomous decisions and evolve without human intervention. Continuing with the previous example, I would do it based on the optimization of economic ratios. This presents us with a double perspective, with challenges and opportunities that are worth highlighting:

  • The artificial intelligence of a company can interact with people. This makes them a representative of the company, for better or for worse.
  • AI can be allowed to make decisions with the same authority as humans.
  • The company can use machine learning to develop a series of skills that can be used by various functional areas of the company.

AI and workers

As with robotics, the risk that the development of artificial intelligence and CNC machining can pose to workers is often discussed. However, 74% of HR experts are convinced that there is nothing to worry about. Of these, 67% believe that the possible elimination of jobs will be clearly offset by the creation of new ones, in such a way that the number of employed will remain stable, while 7% believe that new needs will be created that will require of a greater number of professionals than exists now and companies will have to expand their workforce.

Only 26% of those surveyed think that artificial intelligence and CNC machining will cause the destruction of jobs at a faster rate than new ones will be created and that the total balance will be negative.

Higher productivity

Almost all experts (94%) are sure that AI will serve to increase human performance. So much so that 98% of them consider that the implementation of these systems will lead to an exponential increase in the productivity of companies, although 73% believe that this will require making the most of the true potential of smart technologies. Only 2% of the managers consulted say that productivity growth will not be so high.

In addition to improving productivity, artificial intelligence could also improve the living conditions of workers, as 72% of those surveyed think. These ensure that these technologies will take care of the routine tasks that hinder the work of professionals. 28%, on the other hand, consider that they will bring benefits to employees, but not so many as to say that it will improve their quality of life.

CNC Machining Is Playing More and More Key Role in Rapid Prototyping Industry

/in /by

In the industry of the manufacture of various objects, we can see how new methods are emerging every day that have completely covered the needs of many customers, who before did not even dream of creating everything we have today. It is thanks to this evolution that we have the opportunity to standardize certain processes and techniques, but above all, that we can use the production line as an efficient enough way to achieve perfection in many of the creations and ideas that we need to materialize. This is how we have come to today, where there is a method that has definitely become one of the most important to start the creation of any part or object, it is practically mandatory to stop at this workstation to ensure that the development of the rest of the process is given properly; this is how the creation of the CNC Prototype and other types was born.

Machining in rapid prototype manufacturing

Creating a prototype is a task that all factories should take into account before starting to mass-produce objects, however, the technique that is used to start in this production line is also important. Machining has proven to be the most efficient way we currently have to achieve rapid and perfect prototypes and this technique intervenes in a very exact, economical and fast way. In whatever materials the technique is applied to, it will show that it is the best choice for prototypes.

NX CAM 5Axis Adaptive Milling

CNC Prototype

Thanks to the existence of the CNC Prototype, we have been able to experience great changes in favor of the industry of the creation of objects and parts, and it is that this type of procedure allows the creation of rapid prototypes. This means that in the CNC Prototype manufacturing industry, there is the opportunity to use the material in a specific way, without wasting too much of it, and also immediately correcting certain errors that may occur at that moment.

CNC Aluminum Prototype

We can include in this list several materials that can be used for the manufacturing industry, an example of this variety can include some metals, such as aluminum. The CNC Aluminum Prototype is ideal for the handling and reservation of a rapid prototype, since, unlike other materials, it is easy to manipulate, and it also has all the advantages of the material due to aluminum material is the most commonly used metal in industry . Sometimes it is one of the preferred processes of those who want to be noticed in the market of a certain industry, and this material helps them a lot, since it is very easy to machine a prototype of these. Aluminum Machined Parts is one of the techniques most used in metals , and it is that it allows the creation of parts and objects that have exceeded certain levels of complexity. In this way, it presents a great advantage for the creation of rapid prototypes, since machining does not limit any of the people who require this service.

CNC Prototyping Services at UYEE

For many, finding a company that offers good CNC Prototyping Services seems like a very tedious task, and they think that it may even be impossible, but we know that your opinion can change very quickly. UYEE is a company that has been in charge of developing the best techniques to offer all its clients the best CNC Prototyping Services, in this way they can ensure the continuity of production of certain objects, and also the development of improved versions of these. The best of all is that all the parts or prototype you want to manufacture will be of excellent quality, as they are created with the most modern techniques.

Why Custom Low Volume Aluminum Parts Through by CNC Machining?

/in /by

For the creation of any object, manufacturers have developed various possibilities so that the ideal shape can be chosen for the development of the project. Not in all the productions we can see that similar requirements are met for the creation of products, this is how the services that are given in a personalized way arise, to meet all the specifications of each of the clients. Being part of the manufacturing process of any product is not an easy task, since both manufacturers and customers must try to meet all the objectives in order to be accepted by their future customers and users, and these may have certain differences that must find a common ground. One of the aspects that many manufacturers must consider when recreating their clients’ projects is the quantity and quality of each of the objects that they will offer for them.

Why use aluminum machining ?

It is one of those techniques capable of achieving all the goals that are set in low volume manufacturing. For many, low-volume manufacturing seems very similar to other types of manufacturing, but the truth is that it is very difficult to achieve, because, being a very small production, you have to consider many economic aspects, and use the materials very intelligence and care. For this reason, there are not many processes that support low volume manufacturing, because balancing these aspects is a complicated task, however, to the relief of many customers, aluminum CNC machining service.

The  aluminum machining is a really effective way to treat this type of materials, since it is capable of creating a perfect piece, without wasting too much material, without molding cost, that is, it will use only what is necessary. The aluminum CNC service is undoubtedly a good strategy to be able to recreate low-volume manufacturing parts, since that interaction between the quantity and the quality of the object that is created is quite good.

The Application for Anodizing Aluminum Parts

As a prototype machining manufacturer, we often encounter that clients request their aluminum parts to be anodized .You’ve probably heard of the anodizing process if you work in the automobile sector or as an architect constructing tall buildings. However, anodizing is primarily utilized in the aerospace and electronics sectors, where specific parts must be ‘corrosion-proofed.’ There are several procedures to which various metals used in those sectors may be subjected. Because anodizing can be used for a wide range of metals, from aluminum to titanium, it is typically the best approach to preserve any particular aluminum surface. Aluminum is the most adaptable of them.

As a result, we’ll go through the essential components of anodizing aluminum pieces. We will discuss sealing anodized CNC machined aluminum parts, sharp dip anodizing, etching, voltage, and time, as well as going through and comparing the many types of anodizing procedures, such as hard coating.

Aluminum Anodized

Passivation Process

It is a chemical conversion process that enters the aluminum component and alters its stability. Anodizing creates an exterior barrier of aluminum oxide, which makes the material passive. This coating increases the object’s strength and durability while also protecting its attractiveness.

Anodizing’s Advantages

Electrical and thermal insulation is provided by the most widely utilized anodic oxidation coatings in industrial anodizing. Compared to applying paint to bare metals, the technique enhances the adherence of paint primers and glues. It’s also great for avoiding the galling of threaded components, which is a type of wear produced by adhesion between two moving surfaces.

Rectifiers, Chillers, and Process Equipment

If you’re wondering what type of equipment is required to complete the anodizing process, you might be surprised to learn that there are tiny anodizing kits designed for in-home usage. However, these “anodized aluminum at-home kits” are intended for relatively modest tasks, and they still need extensive knowledge to assure safe application. Several automated anodizing tanks for aluminum anodizing can be used in the apparatus.

Chillers

During the anodizing process, a significant amount of heat is generated. To effectively anodize a part, that heat must be removed, which implies that necessary procedures must be put in place to keep temperatures at an ideal level. Chillers are utilized to level out the metallic oxide deposition, and either water or air chillers aid in the chilling process. The temperature is regulated by using sensors to detect and valves to control it.

Voltage and timing

In two minutes, the technique is explained by Larry Chesterfield’s two-minute read on anodizing current density versus voltage. He provides a few mathematical calculations to assist you in calculating the appropriate voltage and duration to be utilized in proportion to the size of the object being anodized. It may anticipate the time required to produce the desired coating thickness if the current is fixed during the anodized cycle.

Makeup as a Solution

Anodizing aluminum is a labor-intensive process that requires the use of chemical baths and large equipment. Before commencing the procedure, determine the number of liters or gallons of solution required, considering the recommended acid-to-bath ratio (15 percent to 18 percent).

The Oxide Coating Structure

The anodic oxide structure is formed by the aluminum substrate and is fully composed of aluminum oxide. The aluminum atoms are progressively removed from the metal’s surface while the aluminum portion is submerged in the chemical bath, and a current is sent through it.

Pore Composition

The thickness of the aluminum oxide coating layer depends on the voltage applied to the bath and the amount of time the item is submerged in it. Higher voltage accelerates oxidation, and the time of the process influences the coating. Temperature and electrolyte properties, such as temperature and pressure, impact the dissolution rate of the metal surface.

Anodizing Varieties

One (Type II) is commonly referred to as’ regular ‘anodizing, while the other (Type III) is referred to as’ hard ‘anodizing. So, what happened to Type I, and are there any more processes that aren’t covered by the initial classification? We’re here to help you break things down equally and make them more understandable.

CNC aluminum parts

A cost-effective production process

During the low-volume machining process, keep in mind that the end product will be in your hands in no time, as the machines are very precise and fast when milling and turning. Aluminum machining simply takes care of “sculpting” the part until it is able to take the desired shape. The most convenient thing about this type of low-volume production through machining is that the delivery time is very fast, a lot of raw material is saved, and it is possible to work even with the piece that comes from a very complex design. For custom aluminum machining pieces there are no limitations, since the machines are really effective when creating parts, removing all products from any margin of error that may exist, creating parts that were previously believed impossible, and making the dream come true from any manufacturer, even if it is a very small project. If this is the process you need to start your business, go to an expert manufacturer, who can intelligently process your requests, and who is capable of giving you an excellent result, no matter how complex the creation of the parts.

Creation of parts from the service of CNC aluminum machining

Not all companies are capable of developing the ability to create efficient protocols related to the creation of aluminum parts, either in very large batches, or simply in a single prototype. However, to everyone’s relief, companies like UYEE have found the perfect formula to realize the ideas of all their customers, always ensuring the quality of all the objects they manufacture. From aluminum prototype CNC machined to small batch production request . These types of companies apply aluminum CNC machining, and achieve the creation of customized low-volume parts without problems, since within their manufacturing parameters are techniques derived from machining, such as milling and turning. Starting with a small piece of metal, or rather, the most convenient size for this task, the machines begin to do their work with productive and efficient way .

Conclusion

Today ,custom low volume aluminum parts through by CNC machining is sorely welcomed  due to client’s requirements on the quantity ,tolerances ,lead time, finish of diversity. Plus , aluminum is the most widely used metal material in the world .So it will still be a big trend in the future development. If you’d like to check out more about the benefits of aluminum machining and rapid manufacturing service, please get in touch with: info@uyee-rapidprototype.com

 

 

 

Aluminum Heat Sink Parts

CNC Machining For Aluminum Heat Sink Manufacturing

/in /by

There are specific industries that require a helping hand to help them create components capable of fulfilling all their functions. In the electronics industry, it is important to gather all the necessary characteristics to create elements that are really useful, functional, and that can fit perfectly with a whole, that is, with many more elements, which together fulfill a function.

Aluminum MachiningIt is not easy to create quality pieces, it takes an expert in the field to achieve it, and also the knowledge and application of the correct technique. It is extremely important that each piece meets quality standards, and at least with the basic characteristics of itself, which will allow you to develop the multiple tasks that you will have. Well, we know then that in the manufacture of materials and parts used in electronics, it is very necessary to create very precise parts, which ensure the perfect operation of the entire system, which is why very exact and modern procedures are required.

Why Take Aluminum For Heat Sink ?

Metals are the best allies for the manufacture of certain pieces, and one of the most used is aluminum. There are some fundamental pieces that must be created from metals such as aluminum, since it has certain characteristics that absorb and distribute heat very efficiently, and likewise, can release it quickly to continue operating. These very important parts within an electronic circuit are often called heat sinks, and their role within a computer is really key to its operation.

Heat sinks are parts through which the temperature of a component can flow, so that it remains in operation, without heating, or at least that it remains at a temperature that is acceptable enough to continue its normal operation. Normally this piece distributes the heat throughout its surface area, preventing the rest of the components from collapsing. One of the techniques that has achieved excellent results in terms of the manufacture of components such as the heat sink, has been the aluminum CNC machining .

Why Get Heat Sink Made By CNC Machining ?

CNC Aluminum Heat SinkFor the most part, this group of components is manufactured through CNC Aluminum Machining, a technique that has been effective in creating so many other pieces of different metals and their alloys as well. There are so many benefits that aluminum machining is capable of bringing both manufacturers and their customers, however, there are a couple that are more decisive than others. The thermal conductivity of the heat sinks created from CNC machining aluminum is impressive, so they can easily be classified as the best on the market. The heat sinks that are built from the CNC aluminum prototype, usually achieve what could not be done with other previous techniques, and we know that the forms that these components come to acquire are really interesting. Otherwise, they would not be able to fulfill their main functions.

The manufacturers of these components have opted for aluminum CNC machining service to create them, and this allows them to devise new complex geometric shapes that can fulfill their heat sink functions in a more practical way. This is an opportunity that you will certainly not find anywhere, since it is difficult to accomplish a task like this, luckily machining has already come to our lives, to facilitate them, and to allow the creation of so many opportunities for the world. There are many industries that require machining services, so it is important that you can have complete control of the material.

Where Does Heat Sink Apply ?

aluminum Heat SinkOn many occasions, heat sinks are found in multiple places, as they are used in industries such as electricity, transportation, among others, so not all customers will want their components to have similar characteristics to each other. It is here where another of the properties of  aluminum prototype presents diversified solutions, and that is that they are capable of adapting to multiple environments, without risking the integrity of the component, combating humidity, corrosion and other damages.

The complexity to create a quality heat sink is really high, perhaps that is why it is not so common to find reliable manufacturers so that you can recreate these objects, however, there will always be UYEE, a company that is always able to overcome any challenge that is proposed to you, creator of the best quality components.

Watch Case Making By CNC Machining

/in /by

watch case machiningWe have some of customers are from Watch & Jewellery industry . They often place some orders for the watch case making ,from prototype to low volume manufacturing .We make them by CNC machining .For a watch ,the case is the main component of the whole body, it is designed and built to house the movement and all the components needed for the correct functioning of the watch. There are many different shapes of cases, from the simplest to the most complex with various materials .The most important for watch case making is that focus on detail and tolerance ,because it’s a type of small and high precision product .The use of equipment such as precision machine and special tools enable us to reduce production cost and obtain a case with high-level technical and aesthetic characteristics .Precision and attention to detail are our trademark.

There are three metal materials that we often use and recommend:

(1)Stainless Steel 316L Watch Case

Stainless Steel is one of the most used materials for the manufacturing of watch cases since it has always been recognized as an excellent metal given its excellent properties, however, there are different types, each with their own technical and specific characteristics. Here we often use 316 L as one of the best for making excellent watch cases. The “L” indicates that it has fewer parts of carbon (low carbon) inside and therefore has a greater resistance to wear.Sometimes, perhaps machining stainless steel 316L case may get difficult, however, we have the know-how to mill high-quality 316L case time and time again.

(2)Titanium Grade 5 Watch Case

watch case polishedTitanium is used in many sectors, it is recognized as a prestigious material due to its characteristics, it is in fact light, resistant in itself and corrosion. Therefore, even when we talk about owning a titanium watch we mean having a valuable product, with excellent technical characteristics and long-lasting .The disadvantage is that titanium machining turns out to be a harder work, in fact, dedicated tools are needed and some operations, which are good for other metals, must be completely rethought to adapt to the characteristics of titanium. We always prefer to use grade 5 because, even if it is more difficult to work as it is harder, but it allows for better polishing and has superior technical performances.In particular.it has a perfect finishing using PVD surface treatment .

(3) Bronze Watch Case

Bronze is a material that has been used a lot in the watch industry in recent years ,it is easy to work with but has the serious problem of oxidation, despite this it is used a lot because from a chromatic point of view, different and fascinating results are obtained .The problem of oxidation makes the management of the material more difficult, especially when you have finished pieces but not yet ready to be delivered to the customer, therefore greater care is needed than other metals and a deep knowledge of the material itself to know its reactions and features. Bronze must be protected and stored under certain conditions, it is always necessary to take into account the various factors that can alter the surface of the finished pieces, such as: humidity and high temperatures. Machining bronze case is a easy job ,because it’s not hard like Stainess Steel and Titanium metal .

Big PP prototype

How Do We Make Big Polypropylene Plastic Prototype By CNC Machining ?

/in /by

Obviously this is a very successful case what we ever encountered for a big plastic machining to be a single one piece. All details as following:

PP Material Performance

PP (Polypropylene) is a crystalline polymer. Among the commonly used plastics, PP is the lightest, with a density of only 0.91g/cm3. Among general-purpose plastics, PP has the best heat resistance, and its heat distortion temperature is 80-100°C, which can be boiled in boiling water. PP has good stress crack resistance and high bending fatigue life ,light weight, good toughness, and good chemical resistance.

The Application of PP in Prototyping Sector

In rapid prototyping field ,Usually PP parts are made as a single one ,no gluing .That would lost the features and performance of material if PP part split during manufacturing process .No matter big or small part .For simple part ,it’s easy ,but for complex part, that would be high demanding to manufacturer ,from CNC programmer to the operator .It demands high handling ability , especially for a big PP part with complex structure and external shape .As following,we would like to give your a case that we ever made it succesfully for one of our automoive customers.here showing is the size of CAD model (694*413*83 MM).

PP CAD Model

The Option of CNC Machining VS 3D Printing

Like this big and complicated PP part that is not often seen. In West ,perhaps most prototype manufacturers to choose 3D print to make it . However, due to the specification of PP material features ,3D printing can not demand the requirements of customer. It’s the best option to machine the block material ,it’s the same as the product injection ‘ s material ,unlike 3D printing’s .The customer only wanted 6 pieces ,obvious molding is impossible to consider from the economical factor . So machining PP is the only one option for this project .

What You Need to Know For Machining The Big PP Block

We got an order from one of our customers who is from automotive field, the CNC plastic prototype of material is white PP. the size is : 695*413*83mm. It’s a complicated job .We were facing a big challenge after checked out the CAD model .The customer hopes to receive the prototype within 8 days delivery time ,but we thought that’s impossible ,so the customer agreed to postpone two days after discussed .The next we started proceeding the order .Firstly ,We started making the CNC program ,it almost cost 9 hours ,because the programmer needs to clarify each step and take related cutter tools ,and consider the cutting rate for a not hard plastic work piece.Second, be prepared and get ready for CNC machining ,the operator was constant control of cutting speed ,and changed the cutter tools when machining a certain surface.However ,the biggest challenge is how to lock the workpiece with screws to prevent the deformation of the workpiece during the cutting process and the tool from overcutting. So our engineering team had to come up with a solution to solve it .Otherwise ,probably the machining process will be failing.

PP prototype

How to Fix The Problem Caused By Machining ?

After processed half of the whole manufacturing ,we observed the part become deformed .The operator immediately turned over another side to go ahead with machining ,in the meanwhile ,exchanged the tool fixture ,and speed the cutting rate. It cost 26 hours to get it done by CNC machining .For such a big prototype part ,it’s out of shape a bit since the special performance of PP material ,the customer can understand ,and said it’s acceptable .Because it won’t affect the mounting and test. They praised our work after received the CNC prototyping part.

Conclusion

In order to get a wonderful prototype .What you need to consider is not only manufacturing method ,which one is the most optimal,but also analysing on the material option .It’s very crucial to understand the material performance and applicaltion .During production process , the factors of human beings will play an important role in ,such as: skills ,experience,details.
