Example Project

Consumer Electronics Housing Production

A client approached us with a design for a plastic housing used in a consumer electronic device.

We supported the project from early-stage DFM optimization to mold development and mass production.

During development:

  • Optimized internal structure for better moldability
    • Reduced deformation risks during production
    • Ensured stable dimensions across large production volumes

The result:

  • Consistent product quality
    • Smooth transition from prototype to mass production
    • Reduced production risks and rework
