Metal powder molding is a manufacturing process in which various powder metals such as stainless steel, brass, copper, iron and bronze are compressed and then sintered (heated) to metallurgically bond the particles. Material blending allows a certain amount of material properties to produce customizations that are suitable for the desired properties of a particular application.

This part is formed by pressing powder metal or mixed metal powder by special type of hydraulic press, forming mold and punch in precise place. The compressed sheets are then sintered in a controlled furnace in a high temperature atmosphere so that the metal powder particles are metallurgically bound together. This significantly "green" and environmentally friendly method uses 99% of the substances in the mold that produce nitrogen and hydrogen as harmless byproducts.

Supplementary heat treatments can also be used to increase the strength of the material. Other optional finishing steps include milling, drilling and tapping, reaming and other hole sizes, plating, copper, plastic or dipping oil. The result is comparable to the same composition and high concentration of parts and die casting material properties of forged products over plastics. Lower density will, of course, lead to lower physical properties; However, these components can be used in filter or air flow applications.

Injection molding process can directly form thin wall, complex structural parts, product shape has been close to the final product requirements, the size tolerance of parts generally maintained at ±0.1-±0.3. Especially for the machining cost of cemented carbide which is difficult to be machined, it is of great significance to reduce the machining loss of precious metals. Products of uniform microstructure, high density, good performance.
