Metal Injection Moulding (MIM)

Metal injection molding (MIM) is a development of the traditional powder metallurgy (PM) process and is rightly regarded as a branch of that technology.

Carbonyl iron and nickel powders
Fortunately for Metal Injection Molding technology, very fine carbonyl iron and nickel powders were already in industrial production when the process was developed.

MIM technology combines the advantages of powder metallurgy and plastic injection molding , breaks the limits on the shape of the product of traditional metal powder press molding , and absorbs the advantages of plastic injection molding in large quantities and high efficiency of shaping parts with complex shapes.

Metal Injection Molding (MIM) is in use in a wide variety of industries. Aerospace, semiconductor manufacture, automotive, military, and medical are just a few industries that benefit from the chemical machining technology.

The Metal Powder Injection Molding process is typically explained as four unique processing steps (Compounding, Molding, Debinding and Sintering) to produce a final part that may or may not need final finishing operations.

The design engineer can analyse the filling dynamics in thick and thin areas on screen, study the effects of gate position, thermal gradients in the mold and phenomena such as jetting and binder segregation.
