Extremely weak weld lines in PPS products
Sorun Belirtisi
The weld line strength of PPS injection molded products is less than 20% of the bulk.
Neden Analizi
PPS is highly crystalline and strongly oriented, and the bonding force between the two melt streams at the weld line is extremely poor.
Çözüm
Increase melt temperature and mold temperature; optimize gates to reduce the number of weld lines.
Temel Çıkarım
PPS weld lines are the biggest risk point in structural design.
