Extremely weak weld lines in PPS products
문제 현상
The weld line strength of PPS injection molded products is less than 20% of the bulk.
원인 분석
PPS is highly crystalline and strongly oriented, and the bonding force between the two melt streams at the weld line is extremely poor.
해결 방법
Increase melt temperature and mold temperature; optimize gates to reduce the number of weld lines.
핵심 요약
PPS weld lines are the biggest risk point in structural design.
