Low weld line strength of PAR '2079851475616104452
Problem Phenomenon
The weld line strength of the product is significantly lower than that of the body.
Cause Analysis
The high viscosity and high processing temperature of PAR make fusion at the weld difficult.
Solution
Raise the melt temperature and mold temperature to promote fusion; optimize the gate position.
Key Takeaway
PAR weld lines are a difficulty of high-temperature processing.
