Introduction to MIM and PIM

MIM began at the end of 1970s, including product design, mold design, mold design, quality testing, mixing, injection, skim, sintering, two processing, such as 8 important links. With the continuous development of the research and the development of new binder, flour milling technology and the continuous progress of the process, to the beginning of the 90's has been realized. Currently, MIM has been hailed as' one of the world's most popular metal parts forming technology '.

PIM can manufacture of disposable many complex shapes difficult molding parts, such as a variety of external cutting groove, external thread, the tapered outer surface, cross holes, blind holes, grooves and key pin, strengthen rib plate, surface knurling. In addition, the technology can realize automatic continuous operation, the production efficiency is high, and the material utilization rate is almost 100%. And due to the traditional methods of production of tungsten and molybdenum powder with fine particle size by MIM process does not need to increase the cost of raw material powder, so that the tungsten and molybdenum products have significant economic benefits.
