PMMA Weld Lines
Fenómeno do problema
Visible meeting lines on transparent parts, weak strength.
Análise das causas
Two melt fronts merge with insufficient temperature and poor venting; transparent part weld lines are both an appearance and a strength problem.
Solução
①Raise melt temperature and mold temperature; ②Venting at the merging; ③Adjust the gate to avoid optical zones and load-bearing zones; ④Increase speed.
Conclusão principal
Weld lines = position design first.
