How do you increase weld line strenth in GF LCP resin moldings ?
How do you increase weld line strenth in GF LCP resin moldings ?
(OP)
I am looking for tips on how to increase weld line integrity when molding thin walled, long flow front parts.
Do "weld wells" that are trimed off after molding add significant strength ?

Some processing ideas would be to increase your injection speed and holding pressures, along with higher melt and mold temperatures. The wells you mentioned may work if the well is near the bad weldline area. The well may allow the material to "meld" instead of weld.
Good luck.
