Hybrid metal-plastic parts and process for manufacturing the same

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 aplastic in a second mold of an injection molding machine to form the hybrid material part. A hybrid material pump part is disclosed as well.

Description

technical field [0001] The present disclosure relates generally, but not by way of limitation, to hybrid metal-plastic processes for the manufacture of parts. The present disclosure further relates generally, but not by way of limitation, to hybrid metal-plastic components. Background technique [0002] Reduced weight of vehicle components is based on company average fuel economy One of the ways in which the guidelines meet vehicle fuel efficiency goals. Automotive manufacturers are actively exploring various lightweight solutions, including materials and designs, to meet fuel efficiency goals. [0003] In this regard, typical metal vehicle components exhibit excellent strength properties. However, these metal vehicle parts are also generally heavier than similar plastic parts. Plastic vehicle components exhibit reduced weight, however, plastic vehicle components are not preferred in many applications where strength and wear resistance are important considerations. [...
