The powder injection molding (PIM) process provides a possibility for high-volume, low-cost manufacturing of workpiece. During powder injection molding, besides mold design and material characteristics, injection parameters are critical in affecting the capability of molded commodities. Traditional injection molding parameter design relies on the experience of technicians, and it is difficult to ensure the consistency in the quality of injection parts. In this work, we analyze the optimization of technical parameters of current PIM technology and provide some perspectives on the future development of this field.
