摘要

A vehicle door handle apparatus is disclosed that generally includes a structural core and an outer layer. The structural core has an outer surface, a base portion, and a handle portion that extends from the base portion. The outer layer extends about and covers the outer surface of at least the handle portion of the structural core. The structural core is made of a first material that contains an engineering thermoplastic and glass fibers for reinforcement. The outer layer is made of a second material that contains the engineering thermoplastic and a milled material to give the outer layer a metallic surface finish. Non-limiting examples of the engineering thermoplastic are polyoxymethylene and polybutylene terephthalate. A method is also disclosed for producing an injection molded component having a metallic surface finish such as the disclosed vehicle door handle apparatus.
