EV Headlight Housing Prototype

Launch-ready prototypes with faster approval and lower scrap.

Customer Requirement

The customer needed a lightweight aluminum headlight housing with cosmetic precision and stable sealing surfaces for a new EV platform.

Challenges

  • Thin wall sections risked distortion during machining.
  • Visible surfaces required a clean finish with no tool marks.
  • The launch program needed prototype approval in under one week.

Solution

We optimized the fixture strategy, adjusted machining order for thin-wall stability, and synchronized finishing inspection with the prototype schedule.
