Injection molding

In order to produce near net shape components, MIM technology uses a type of machine which is similar to plastic injection molding machines and molds. This enables design flexibility that characterizes plastic injection molding, but allows to create metallic structural parts.

Unlike thermoplastic molding, where the molded component is often the final product, MIM components need a subsequent thermal process to remove polymers contained in the binder system. This causes a controlled shrinkage of MIM components and it is the reason why the mold cavities are larger than the final part’s size.
