Mould Structure & Design Description

The mould core insert functions as a critical forming element within the injection mold cavity system. Using 1.2344 hardened tool steel, the insert maintains structural integrity under repeated thermal cycling. Polished working surfaces reduce material adhesion and improve filling balance, contributing to stable molding performance and reduced maintenance frequency.
