Sticking to Mold of PCTG Injection Molded Products
Fenómeno del problema
PCTG products are difficult to demold and stick to the mold surface.
Análisis de la causa
PCTG melt has strong adhesion to metal, the demolding draft is insufficient, and the mold surface has no release coating.
Solución
Increase the demolding draft ≥2°; use chrome-plated or DLC coated molds; appropriately reduce the mold temperature.
Conclusión clave
PCTG mold sticking requires mold surface treatment and demolding design.
