Proper Group International is a mid-sized motor vehicle manufacturing company based in Warren, Michigan. It offers end-to-end support for automotive component production, from rapid prototyping to production-scale injection molding and precision machining.

This combination positions the company to serve the transportation industry's molding and component-manufacturing needs with integrated capabilities.

Proper Polymers manufactures injection-molded plastic subcomponents for fascias and interior trim, and offers high-die-change and material-change management, along with sub-assembly, modular-build options, and finishing such as painting.
