Mushroom Head Screw & Threaded Core Sets | Micron-Level Packaging Mold Tooling

Product Overview

The high-precision thread core with button mushroom screw is a custom-manufactured injection mold component designed for packaging molds requiring stable thread demolding and tight dimensional control. Manufactured with CNC machining and controlled assembly accuracy, this thread core achieves a tolerance of ±0.005 mm, ensuring consistent performance in high-cycle packaging applications.

Key Features & Technical Advantages

• Thread core tolerance controlled within ±0.005 mm

• Integrated button mushroom screw for stable positioning and demolding

• Precision CNC machining for accurate thread geometry

• Suitable for unscrewing or threaded demolding systems

• Stable repeatability in multi-cavity mold configurations

• Fully custom manufactured according to customer drawings (Built-to-Print)

Applications & Industry Use

• Packaging injection molds with threaded structures

• Bottle cap and closure molds

• Daily packaging and container component molds

• Precision molds requiring controlled thread engagement

Mold Structure & Design Description

This thread core assembly consists of a precision-machined threaded core combined with a button mushroom screw structure, enabling accurate axial positioning and controlled rotational or linear demolding. The design supports consistent thread engagement and reduces wear during repeated molding cycles. All structural dimensions are manufactured strictly according to approved 2D drawings or 3D CAD data.
