Extremely weak weld lines in PPS products
Fenómeno do problema
The weld line strength of PPS injection molded products is less than 20% of the bulk.
Análise das causas
PPS is highly crystalline and strongly oriented, and the bonding force between the two melt streams at the weld line is extremely poor.
Solução
Increase melt temperature and mold temperature; optimize gates to reduce the number of weld lines.
Conclusão principal
PPS weld lines are the biggest risk point in structural design.
