TiN Coated H13 (1.2344) Die Casting Mold Parts | Custom Automotive Core Pins

Product Overview

Tin coated metric core pins are precision mould components designed for high-load injection and die casting mould systems requiring enhanced wear resistance and stable surface performance. Senlan Precision manufactures these core pins strictly according to customer drawings, focusing on dimensional accuracy, coating consistency, and long-term stability in high-cycle moulding operations.

Core Features & Technical Advantages

• Built-to-Print manufacturing based on customer technical drawings

• Tin coating for improved surface hardness and reduced friction

• Metric dimension standards with controlled tolerance

• Stable concentricity and straightness for precision mould alignment

• Enhanced wear resistance for extended service life

• Compatible with multi-cavity and replaceable core pin systems

Applications & Industry Use

Tin coated metric core pins are commonly applied in:

• Plastic injection moulds for packaging components

• Closure and cap mould systems with high production cycles

• Medical mould tooling requiring stable surface conditions

• Multi-cavity moulds with interchangeable core pin designs

• Export-oriented OEM mould projects

All applications are limited to industrial mould tooling systems.

Mould Structure & Design Description

Within an injection mould, the metric core pin functions as:

• A forming element defining internal or external product geometry

• A precision-aligned component interacting with cavity inserts

• A wear-critical part subjected to repeated injection pressure

Key design considerations include:

• Core pin diameter and length tolerance

• Concentricity between pin body and functional features

• Coating thickness and adhesion stability

• Fit accuracy within mould plates and inserts

Manufacturing Capability & CNC Machining

Senlan Precision utilizes advanced CNC machining and finishing equipment from MAKINO and HARDINGE to manufacture tin coated core pins with consistent quality.

Key processes include:

• Precision CNC turning and milling

• Grinding for diameter and straightness control

• Surface preparation prior to tin coating

• Controlled coating application and thickness inspection

• Full dimensional and surface verification
