Metal Powder Injection Molding (PIM) is Suitable for Which Type of Industries?
views, Updated: 2021-09-29
In recent years, with the 3C industry starting to take a more high-end metal line or even ceramic line, metal powder injection molding can not be more appropriate from the quantity and processing method. So what are the applications of PIM in the industry?
The application of metal powder injection molding in the industry can be divided into civil and military. The civil category mainly refers to 3C, medical treatment, tools, automobile, communication, lighting, wearing, locks, and catering. The military industry refers to aerospace and machinery. The details are as follows:
In the 3C industry, the use of MIM is becoming more and more popular. From the first mobile phone vibrator to the card slot and metal parts on the charger in the 3C mobile phone industry, the 3C industry takes quantity first, and for MIM, the use in this industry is like a duck to water..
In the medical industry, MIM is also widely used in foreign countries, for example, dental hoops' production. CIM is also used to make braces, which is more anti-allergic than MIM. There are also living forceps for making in the medical industry, similar to those used for gastroscopy.
In the aspect of tool manufacturing, PIM is also used. Many tools use cemented carbide materials, which have high hardness. If other production methods are used, such as turning an internal thread and an external thread, the PIM process can be successfully made in one step. In contrast, other processes will require tools with higher hardness than cemented carbide.
In the automobile industry, PIM is also used. Similar to those turbines and rotors, its structure is quite complicated. If PIM is used for production, it will be more appropriate.
To distinguish 3C industry, some optical brazing bases and joints can be made by the PIM process, and their structures are relatively complex. For the huge demand in the future, PIM technology is a right solution.
In the lighting industry, alumina burner is used frequently, which requires large output and complex structure.
More industries tend to use PIM to produce luxury goods, especially in the CIM industry. MIM is used in the watch cases, while in the high-end watch industry, ceramics are also used. Some limited edition and commemorative edition are especially suitable for CIM production. On the one hand, the ceramic is wear-resistant, but it is challenging to make special ceramic powder.
PIM technology is also used widely in the locks’ industry for locks production.
Many successful products are examples of ceramic grinder for grinding pepper and the grinder for grinding coffee beans.
In general, in the firearms industry, the parts' structure is relatively complex, and MIM is used for mass production.
In this industry, the materials‘ requirements are exceptionally high. One kind of fastening device made of ceramics is made by the CIM process, but the quantity is not too large, mainly for research and development.
As a question, what metal powders are available for injection molding? The answer is, AEM deposition, as a professional metal powder supplier, provides cobalt powder, chromium powder, hafnium powder, and other metal powders. See the following table for details:
