Abstract: In order to improve the production efficiency of stainless steel handle of cabinet plug-in box and the appearance quality, this paper puts forward innovatively application of powder injection moulding (PIM) technology to manufacturing of stainless steel handle and analyzes in detail the manufacturing process of this handle. Production results show that PIM technology can meet the precision requirements of drawings. The handle enjoys stable quality, beautiful appearance and good consistency. Compared with pure NC machining, this technology can greatly improve the production efficiency, shorten the production period and reduce the cost. Therefore, the application of PIM technology to manufacturing of stainless handle is a very effective production mode. Besides, it shows great application prospect in manufacturing of the hydraulic and liquid cooling pipe connector.
