• Stable dimensional accuracy under repeated thermal cycling

• Good toughness for high-pressure mold environments

• Consistent surface condition for reliable molding and demolding

• Suitable for multi-cavity and long production runs

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

Applications & Industries

These nitrided 1.2344 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

• Industrial die casting and injection mold applications

They are especially suitable for applications requiring heat resistance, surface durability, and repeatable mold performance.

Mold Structure & Design Description

Core pins made from nitrided 1.2344 steel are installed on the core side of injection or die casting molds to form internal product features.
Key design considerations include:

• Accurate pin diameter, straightness, and functional tip geometry

• Proper fit and alignment with surrounding mold components

• Structural strength to withstand injection pressure and thermal load

• Compatibility with modular and multi-cavity mold designs

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 nitrided core pins using advanced CNC machining and finishing technologies.
Our production facilities are equipped with high-precision machining centers and CNC systems from MAKINO (Japan) and HARDINGE (USA), enabling:

• High-accuracy CNC turning and milling

• Stable dimensional control before and after heat treatment

• Consistent surface finish prior to nitriding
