Metal powder injection molding MetalPowderInjectionMolding (MIM) is modern plastics. Injection molding technology In the field of powder metallurgy, a new technology of near net shape forming of powder metallurgy has been formed. The basic process is: first, the solid powder the organic binder are evenly mixed, granulated, then injected into the mold cavity in the plasticizing state (~ 150 degrees Celsius) to solidify into the mold cavity. Then the binder is removed by chemical thermal decomposition the forming blank, finally sintered to densify the final product. Compared with traditional process, it has the characteristics of high accuracy, uniform structure, excellent performance low production cost. Its products are widely used in electronic information engineering, biomedical equipment, office equipment, automobiles, machinery, hardware, sports equipment, weapons, aviation other industrial fields. Therefore, the international community generally believes that the development of technology will lead to the technological revolution of parts forming technology, which is called "today's forming technology". Be well received Part "" twenty-first Century molding technology ". The following is a detailed account of the application of MIM injection molding in the automotive industry:

MIM injection molding can design small surprises of automotive parts into a whole assembly, so that parts can be smaller, integrated miniaturized while meeting the requirements of performance, at the same time, they can also reduce costs.

You can also create parts with very complex shapes, such as external grooves, external threads, cross holes, blind holes, stiffeners, grooves key pins.

Because the development of automobiles must be comfortable, intelligent, environmental protection, energy saving lightweight. Therefore, the technological characteristics of MIM injection molding determine that it has a very broad prospect in the automotive parts industry.
