PETG injection molded product mold sticking
Sorun Belirtisi
PETG injection molded products are difficult to demold, adhere to the mold surface, and the products deform and are scratched during demolding.
Neden Analizi
The PETG melt has strong adhesion to the metal mold, the draft angle is insufficient, the mold surface lacks a release coating, and the mold temperature is high.
Çözüm
Increase the draft angle to ≥2°; use surface treatment (chrome plating, DLC coating) to reduce demolding force; appropriately lower the mold temperature.
Temel Çıkarım
PETG mold sticking is a common problem; mold surface treatment and demolding design are the main improvement directions.
