Metal Injection Molding

After molding the part undergoes conditioning operations to remove the binder debinding and densify the powders.

Metal injection molding.

The metal injection molding process is typically explained as four unique processing steps compounding molding de binding and. A feed stock of the alloy is made into a fine powder and mixed with a polymer powder. The metal injection molding process combines the design flexibility of plastic injection molding with the strength and integrity of wrought metals to offer cost effective solutions for highly complex part geometries. 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.

Metal injection molding mim is a variation on traditional plastic injection molding that enables the fabrication of solid metal parts utilizing injection molding technology. Mim is a process in which granulated metal powder is mixed with a binder substance to form feedstock that is shaped and solidified. Metal injection molding mim merges two established technologies plastic injection molding and powdered metallurgy. A continuous mass of this mixture is conveyed with a rotating screw through a heated barrel.

Metal injection molding mim is a manufacturing process that combines the most useful characteristics of powdered metallurgy and plastic injection molding to facilitate the production of small complex shaped metal components with outstanding mechanical properties. Mim works similar to the other injection molding processes powdered metal is combined with a binding material and then injected into a mold where it s left to form and curate. The end result is a metal part. The metal injection molding mim process meets this demand and provides significant cost savings for industries such as automotive industrial medical and electronics.

This frees designers from the traditional constraints associated with trying to shape stainless steel nickel iron copper titanium and other metals. Why metal injection molding. Powder metal injection molding. The mim process can replace other metal forming techniques such as investment casting and machining.

In this process the raw material referred to as the feedstock is a powder mixture of metal and polymer.
