PCTG melt has strong adhesion to metal, the demolding draft is insufficient, and the mold surface has no release coating.
Lösung
Increase the demolding draft ≥2°; use chrome-plated or DLC coated molds; appropriately reduce the mold temperature.
Wichtigste Erkenntnis
PCTG mold sticking requires mold surface treatment and demolding design.
