Applications & Industries

These 1.2344 TiN coated 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 controlled wear behavior and long service life

They are especially suitable for applications requiring dimensional stability, surface durability, and repeatable molding performance.

Mold Structure & Design Description

Core pins are installed on the core side of injection molds and directly define internal product geometry or functional features.
Key design considerations include:

• Accurate pin diameter, straightness, and tip geometry

• Proper fit and alignment within mold assemblies

• Structural strength to withstand injection pressure and repeated cycles

• Compatibility with multi-cavity mold layouts

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 precision mold 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:

• Machining accuracy up to ±0.002 mm

• Stable tolerance control for slender and high-precision core pins

• Consistent surface quality prior to coating

• Reliable repeatability across production batches

TiN coating is applied after machining and surface preparation to ensure uniform coating thickness and performance.
