Abstract
A process for constructing a hybrid material part includes mixing a metal powder and a binder to form a compounded mixture, heating the compounded mixture, injecting the compounded mixture into a first mold to form a green part, and debinding the green part to form a brown part. The process further includes sintering the brown part to form a sintered part, and over-molding the sintered part with a plastic in a second mold of an injection molding machine to form the hybrid material part. A hybrid material pump part is disclosed as well.

A process for constructing a hybrid material part comprising:
- mixing a metal powder and a binder to form a compounded mixture;
- heating the compounded mixture;
- injecting the compounded mixture into a first mold to form a green part;
- debinding the green part to form a brown part;
- sintering the brown part to form a sintered part;
- and
- over-molding the sintered part with a plastic in a second mold of an injection molding machine to form the hybrid material part.
A hybrid material pump part comprising:
- a first housing portion formed with a metal powder and a binder injection molded structure;
- a second housing portion formed by a plastic structure over-molded onto the first housing portion;
- a drive hub arranged in the first housing portion;
- a plurality of slots arranged in the drive hub;
- and
- a plurality of vanes arranged in the plurality of slots,
