Challenge
A large flat cover with snap locks required stiffness and low warp while keeping sealing edges consistent across temperature variation.
EV battery systems
Automotive Battery Cover Mold
Large automotive battery cover mold built for low warp, stable sealing edges and fast EV launch support.
Solution
The team optimized the runner layout, strengthened venting near the latch area and adjusted cooling channels to reduce corner pull.
Result
The customer reached sealing validation in the second trial and shortened SOP preparation by nearly two weeks.
Program Notes
The program supported an EV platform launch where sealing consistency and fast validation mattered more than decorative surface treatment.

Automotive Automotive Instrument Panel Bracket Mold
Interior bracket mold for a German automotive supplier with cosmetic surface control and insert-fit stability.
- Challenge
- The part combined deep ribs, cosmetic grain and metal insert clearance, which created a high risk of sink marks and trim distortion.
- Result
- The first sampling round achieved stable assembly dimensions, reduced sink visibility and met the customer's PPAP timing target.
Automotive Automotive Air Duct Housing Mold
Two-cavity air duct housing mold tuned for leakage control, clean shutoff and stable clip force.
- Challenge
- The housing used thin walls, multiple clips and an airflow channel that was sensitive to flash and mismatch.
- Result
- The molded housing met leakage and clip force targets while keeping the launch timing on schedule.
Automotive Automotive Door Trim Clip Mold
High-cavity automotive clip mold built for cavity balance, clean ejection and stable retention force.
- Challenge
- Small clips demanded tight dimensional consistency across eight cavities, while ejector stress risked whitening at the hook area.
- Result
- Retention force stayed within the client's range and cavity balance supported immediate pilot production.
