• Corrosion-resistant material options for extended service life

• Precision CNC machining with tolerance control up to ±0.01 mm

• Stable concentricity and fit between core pins and sleeves

• Consistent surface quality for reliable molding and demolding

• Suitable for high-cycle and multi-cavity mold systems

• Reliable interchangeability for replacement components

• Fully customized / OEM / Built-to-Print manufacturing

Applications & Industries

These corrosion-resistant core pins and sleeves are widely used in:

• Injection molds for packaging caps and closures

• Mold systems for bottle caps and sealing components

• Medical packaging and syringe-related injection molds

• Industrial die casting and precision injection mold assemblies

They are especially suitable for applications requiring tight tolerances, corrosion resistance, and repeatable mold performance.

Mold Structure & Design Description

Core pins and sleeves are installed as matched functional components within injection and die casting molds, forming internal geometries while maintaining precise alignment.
Key design considerations include:

• Accurate diameter and concentricity control between pin and sleeve

• Proper clearance and fit for smooth mold operation

• Structural stability under injection pressure

• Compatibility with modular and multi-cavity mold designs

All components are designed and manufactured strictly according to customer drawings to ensure correct assembly and stable mold performance.
