Mim Metal Injection Molding

The metal injection molding mim process starts with the compounding or feedstock preparation process.

Mim metal injection molding.

Metal injection molding mim merges two established technologies plastic injection molding and powdered metallurgy. Mim is characterized by a wide range of materials a high degree of flexibility in the design of parts great precision and reproducibility. Metal injection molding can be used to form complex parts as easily as simple ones. This frees designers from the traditional constraints associated with trying to shape stainless steel nickel iron copper titanium and other metals.

The metal powder to binder ratio is approximately 60 40 by volume. The process is generally best suited to parts measuring less than 6 mm thick and weighing less than 100 g. Fine metal powder less than 20µ particle size is blended with thermoplastic and wax binders in precise amounts. Newer binder removal techniques however have enabled the processing of cross sections above 12 5 mm and up to 400 g.

Metal injection molding combines the well known advantages of sinter materials with the possibilities for shaping offered by plastic injection molding.
