MIM is a new kind of net shape technology in manufacturing, which is applied to produce some complex parts. The MIM process of Housing1533 is analyzed. The optimization of process, self-developed binder system and SPC technology for injection molding & the weight controlling of green part are applied to the MIM process. After sintering, the linear tolerance of ±0.2% of Housing1533 is reached, and its mechanical property & precision meet with the service properties of the product. So, the MIM technology of Housing1533 can save the raw materials a great quantity and decrease cost, and the productivity is increased highly.
