General Specifications Common to All Class Molds: Customer is to approve mold design prior to start of construction. All molds are to have adequate channels for temperature control. Wherever feasible, all details should be marked with steel type and Rockwell hardness. Customer name, part number and mold number should be …

Unscrew mold tooling is a specialized injection molding solution for producing threaded plastic parts (e.g., bottle caps, medical vials, automotive fasteners), relying on rotational core movements to release threaded components without damaging the helical structures. Unlike standard molds with straight-pull ejection, it uses mechanical, hydraulic, or motor-driven rotation to unscrew …
