Product stress cracking
문제 현상
Surface microcracks appear on the product after processing or during use
원인 분석
Molding internal stress too large; mold temperature too low <120°C, quenching freezes the stress; design defects such as sharp corners on the product
해결 방법
Increase the mold temperature to 140-160°C; anneal the product at 180°C/2h to eliminate stress; avoid sharp corners and abrupt transitions in product design
핵심 요약
The stress cracking problem of PES can be solved by annealing and optimizing the design
