Toughness and Hardness of Metal injection molding process

Metal injection molding process will encounter a variety of materials and toughness problems. Some is not easy to adjust, some can be modified in some way, such as dipping, hot pressing or liquid phase sintering, whose effect is very good. But if you are using superfine powder and combine hot isostatic pressing process, the hole on MIM parts’ surface can get basic fusion, material density is close to theoretical limits, its toughness is obviously improved. Besides toughness, everyone is concerned about the hardness of products. In fact, harness has less relationship with metal injection molding process, mainly depends on the chosen material.
