Low Weld Line Strength in PC '2079851475616104452
Problem Phenomenon
The weld line strength of PC products is far lower than that of the body.
Cause Analysis
The temperature of the two melt streams when converging is not high enough to fully fuse, and poor venting hinders the fusion.
Solution
Increase the melt temperature and mold temperature; optimize the gate position to reduce weld lines; improve the venting.
Key Takeaway
PC weld lines are the weak strength points of structural parts.
