FineMIM

Metal injection molding (MIM) is a hybrid technology which integrates the shaping capability of plastic injection molding and materials flexibility of conventional powder metallurgy. MIM is preferred for mass manufacturing of small, intricate geometric components of a variety of materials as it can achieve 95% to 98% of its wrought materials properties at a much lower cost.

The initial step to MIM is material selection and preparation. Once the appropriate combinations of metal powder and plastic binders are blended and compounded, an injection moldable feedstock is produced.

Using an injection-molding machine, the parts produced are then subjected to a binder removal process. Depending upon the type of binder used, different methods of debinding are applied.

The parts, after debinding, then go through a sintering process to ensure the parts are of the right material composition, physical properties and correct geometry.
