Applications & Industries

This threaded unscrewing core and lead nut mould parts set is widely used in injection molds for:

• Bottle caps and closures with internal threads

• Packaging containers requiring screw-type demolding

• Medical plastic components with threaded structures

• Pharmaceutical and laboratory plastic products

Typical customers include packaging manufacturers, cap and closure producers, medical consumable manufacturers, and OEM injection mold makers.

Mold Structure & Design Description

Threaded unscrewing cores and lead nuts are critical functional components in injection molds designed for products with internal threads.
The system converts linear mold opening motion into controlled rotational movement, enabling automatic and damage-free demolding of threaded parts.
Key design considerations include thread accuracy, torque transmission, synchronization across multiple cavities, and compatibility with multi-cavity mold layouts.

Manufacturing & CNC Machining Capability

All unscrewing cores and lead nuts are manufactured in-house using precision CNC machining equipment to ensure dimensional accuracy and functional stability.

Manufacturing capabilities include:

• High-precision CNC turning and milling

• Thread machining with strict tolerance control

• Precision grinding for functional surfaces

• Stable machining processes for mould components requiring rotational accuracy

In-house inspection equipment is applied throughout the machining process to ensure consistency across all cavities in multi-cavity injection molds.
