Mim Metal Injection Molding

Metal injection molding mim is a metalworking process in which finely powdered metal is mixed with binder material to create a feedstock that is then shaped and solidified using injection molding the molding process allows high volume complex parts to be shaped in a single step.

The metal powder to binder ratio is approximately 60 40 by volume. Metal injection molding combines the well known advantages of sinter materials with the possibilities for shaping offered by plastic injection molding. Metal injection molding mim merges two established technologies plastic injection molding and powdered metallurgy. After molding the part undergoes conditioning operations to remove the binder debinding and densify the powders.

The metal injection molding mim process starts with the compounding or feedstock preparation process. Mim is characterized by a wide range of materials a high degree of flexibility in the design of parts great precision and reproducibility. Learn about metal injection molding and find out if you can free yourself from the traditional constraints of trying to mold stainless steel nickel iron copper titanium and other metals in your part designs. 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.
