TiN Coated Stepped Core Pins | H13 Precision Components for Die Casting & Injection Molds

Product Overview

TiN coated stepped core pins are precision mold components used in injection and die casting molds where multi-diameter geometry, wear resistance, and dimensional stability are required. Manufactured through CNC turning, precision machining, and TiN surface coating, these components provide reliable performance under repeated molding cycles. All parts are custom produced strictly according to customer drawings and technical specifications.

Key Features & Technical Advantages

• Precision-manufactured stepped core pins for mold applications

• CNC turning combined with fine machining for stepped geometries

• TiN coating to enhance wear resistance and reduce friction

• Stable dimensional accuracy for multi-diameter functional areas

• Consistent surface quality for reliable molding and demolding

• Suitable for high-cavity and long production runs

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

Applications & Industries

These TiN coated stepped core pins are widely used in:

• Injection molds for packaging caps and closures

• Mold systems for bottle caps and sealing components

• Medical packaging molds and syringe-related tooling

• Precision molds requiring stepped internal or external features

They are particularly suitable for applications requiring accurate stepped geometry, surface durability, and repeatable mold performance.

Mold Structure & Design Description

Stepped core pins are installed on the core side of injection or die casting molds and are used to form internal product features with multiple diameter transitions.
Key design considerations include:

• Accurate step position and diameter control

• Smooth transitions between stepped sections

• Proper alignment and fit within mold assemblies

• Structural strength to withstand injection pressure and repeated cycles

All core pins are designed and manufactured strictly according to customer drawings to ensure correct assembly and stable mold operation.

Manufacturing Capability & CNC Machining

Senlan Precision manufactures TiN coated stepped core pins using advanced CNC machining and finishing processes.
Our production facilities are equipped with high-precision machining centers and CNC lathes from MAKINO (Japan) and HARDINGE (USA), along with other internationally recognized equipment, enabling:

• High-precision CNC turning for stepped geometries
