  Excellent hot strength, thermal fatigue resistance, and dimensional stability

• Parallelism Control ≤ 0.01 mm
  Ensures precise alignment between core and cavity in mould assemblies

• High-Precision CNC Machining
  Stable diameter, straightness, and concentricity throughout the pin length

• Optimized for Die Casting & Injection Mould Service
  Designed to withstand thermal cycling and mechanical load

• Custom / OEM / Built-to-Print Manufacturing
  Produced strictly according to customer drawings and technical specifications

Application Scenarios / Industry Applications

• Injection Molding Mould Core Systems

• Die Casting Mould Components

• Bottle Cap and Closure Moulds

• Medical Packaging and Syringe Moulds

• Multi-Cavity and High-Output Mould Tools

These precision core pins are typically used in mould structures where repeatable alignment, uniform cavity formation, and long service life are required.

Mould Structure & Design Explanation

In injection molding and die casting moulds, core pins are critical for forming internal features and maintaining cavity geometry.
The parallelism of the core pin directly affects:

• Product dimensional consistency

• Wear distribution between core and cavity

• Mould stability during high-cycle production

A controlled parallelism of 0.01 mm significantly reduces misalignment and improves mould life.
