According to statistics, powder injection molding is one of the most popular technologies nowadays.
The powder injection molding material has been developed from the early stage of the iron base, cemented carbide, ceramics, which is not sensitive to impurity content, is not very strict system function demand, to the high temperature nickel base alloy, titanium and niobium material. The material use category also developed from the layout material to the functional materials, such as heat sink material, magnetic material and shape recall alloy. The metal injection molding technology can be used to form a variety of different components, so the composite layout with sandwich mode can be obtained. For example, a combination of 316L stainless steel and 17-4ph alloy can be used to complete mechanical

functions.

A significant development direction of powder injection is closely related to microsystem technology. In the context of Microsystems, such as electronic information, microchemistry, medical devices, etc., the equipment is constantly miniaturized and the functions become more and more complex. And the powder injection molding technique supplies the possibility of completion.
