Advantages of MIM in Metal Injection Molding

Advantages of MIM:

1. High efficiency, good at mass production of batch parts

Metal Injection MoldingMIM technology uses molds. Because of the high degree of production automation, its service life is equivalent to that of engineering plastic injection molding tools. Because of the use of metal dies, MIM is suitable for mass production of parts.

2. More refined parts

Alloying has good flexibility, wide application range of materials, the density of products reaches 95% - 99%, the internal organization is uniform, without internal stress and segregation, the surface finish is good, the precision is high, and the typical tolerance is ± 0.05mm.

3. Substantial energy and material conservation

Metal Injection MoldingMIM can use almost all metal materials. Considering the economy, the main application materials include iron based, nickel based, copper based, titanium based metals or alloys. Generally, the utilization rate of metal processing and molding is relatively low. For example, the utilization rate of raw materials for the metal shell of LeTV MAX mobile phone is less than 10%, and most of the aluminum alloys become debris. MIM can greatly improve the utilization rate of raw materials, which is 100% theoretically.

4. Structural parts with highly complex structure can be formed

Generally, the tolerance accuracy of ± 0.5% can be achieved with MIM, and higher dimensional accuracy can be achieved with other processing methods. Basically, all structures that can be realized by injection mold can be applied to MIM.

5. Environmental protection and safety

It is pollution-free and can realize continuous mass clean production. It is a near net forming technology and can effectively avoid material waste.

6. More material choices

Most metal materials can be used in MIM. In consideration of economy, the main application materials include iron base, nickel base, low alloy, copper base, high-speed steel, stainless steel, gram valve alloy, hard alloy and titanium base metal.

Qinhuangdao zhongwei Precision Machinery Co., Ltd. has both PM and MIM industries and enterprises with a certain scale. MIM combines the advantages of powder metallurgy and plastic injection molding technologies, breaking through the limitations of traditional metal powder molding process on product shape（ https://www.zw-metalware.com/ ）The mechanical parts with good mechanical properties and surface quality can be sintered by using the technical characteristics of metal powder. At the same time, plastic injection molding technology can be used to produce many parts with complex shape features in large quantities and efficiently. Such as various external grooves, external threads, tapered external surfaces, cross through holes, blind holes, recesses and key pins, stiffening rib plates, surface knurling, etc., parts with the above characteristics cannot be obtained by conventional powder metallurgy methods, precision casting and other processes. As an injection molding technology for manufacturing high-quality precision parts, MIM technology has incomparable advantages over conventional powder metallurgy machining and precision casting methods.
