What kind of automotive parts can we make?
Automotive programs require metal and plastic parts with tight tolerances, certified materials, and excellent quality control.
Case study
Rapid tooling for tail lights
The combination of rapid tooling and injection molding allows automotive companies to order small batches of moldings in a much shorter timeframe than regular injection molding.
3ERP fabricated hundreds of car tail lights, including housing, reflector, light guide, bezel, outer lens, and other components.
