Low Weld Line Strength in PC '2079851475616104452
Fenómeno del problema
The weld line strength of PC products is far lower than that of the body.
Análisis de la causa
The temperature of the two melt streams when converging is not high enough to fully fuse, and poor venting hinders the fusion.
Solución
Increase the melt temperature and mold temperature; optimize the gate position to reduce weld lines; improve the venting.
Conclusión clave
PC weld lines are the weak strength points of structural parts.
