Beryllium Copper Preform Thread Cores | Precision CNC Mold Inserts

Product Overview

The Beryllium Copper Thread Core Insert is a precision CNC-machined mold component designed for preform injection molds requiring efficient heat transfer and stable thread demolding performance. Manufactured from high-conductivity Cu-Be alloy, this core insert supports consistent cycle times, accurate thread geometry, and long-term dimensional stability in high-output preform molding applications.

Key Features & Technical Advantages

• Manufactured from beryllium copper alloy for superior thermal conductivity

• Precision CNC machining for accurate thread profile and concentricity

• Optimized for preform neck finish and threaded areas

• Excellent balance between strength, wear resistance, and heat dissipation

• Suitable for high-cavity, high-cycle injection mold systems

• Fully customizable based on customer drawings (Built-to-Print)

Applications & Industry Use

• PET preform injection molds

• Thread core systems for bottle neck finishes

• High-speed, multi-cavity preform molds

• Packaging molds requiring enhanced cooling efficiency

Mold Structure & Design Description

The beryllium copper thread core insert is typically installed in the neck or thread area of preform molds. Its high thermal conductivity accelerates heat extraction from the threaded region, helping to reduce cycle time while maintaining stable thread geometry. The insert can be designed as a fixed or replaceable core depending on mold structure and maintenance requirements.
