Metal Injection Molding – MIM

PMIeng provides Metal Injection Molding to a variety of industries.

Tooling

This is a combination of plastic injection molding and powder metal. The tooling consists of an aluminum die, similar to a plastic injection molding tool. The media is a combination of extremely fine powder metal mixed with a polymer binder in about a 75/25 ratio. The cavity in the tool will be about 20 to 25% oversize of the intended finished part.

Sintering

The media is injected and the parts taken out and sintered. The sintering process pulls the binder out and compresses the metal to 98% or so density. The sintering process is delicate as the parts can droop and sag if not set up properly. Extreme cross sectional differences make sintering difficult.

Tolerances

But, for a part that is designed for the process; tolerances can be held extremely tight and strength characteristics are very good. Some limitations are the size of the part is typically smaller than a golf ball and minimum quantities are needed to optimize the sintering batch.
