Plastic Injection Molding Warpage — Causes and Fixes：核心技术...
-
Warpage in injection molded parts is caused by uneven shrinkage. Common fixes:
- Balance mold temperature (core vs cavity differential < 10C)
- Optimize cooling channel design
- Use uniform wall thickness (varies < 25%)
- Increase hold pressure and time
- Consider filler materials (glass fiber reduces shrinkage)
