Custom Unscrewing Molds for Plastic Injection 800K-1.2M Shots Life

Product Process

Screw-off molds are specialized molds for producing threaded plastic parts. They utilize a rotating mechanism for smooth demolding. Compared to forced ejection, this process avoids thread damage and ensures high precision and consistency.

Process Flow

Confirm thread specifications and demolding direction
Mold flow analysis predicts filling and cooling performance
Precision machining of thread cavities
Assembly of screw-off drive and cooling devices
Trial mold verification for stability
