H13 (SKD61) Nitrided Core Pins | High-Precision Die Casting Mold Inserts

Product Overview

SKD61 nitrided core pins and inserts are precision die casting mold components designed for injection mold applications requiring high thermal stability, wear resistance, and dimensional reliability. Manufactured through precision CNC machining, controlled heat treatment, and nitriding processes, these components maintain stable geometry under repeated molding cycles. All parts are custom produced strictly according to customer drawings and technical specifications.

Key Features & Technical Advantages

• Manufactured from SKD61 (H13 equivalent) hot work tool steel

• Nitriding surface treatment for enhanced wear resistance and fatigue strength

• Stable dimensional performance under high temperature and pressure

• Good toughness for long service life in high-cycle mold operation

• Consistent surface condition for reliable molding and demolding

• Suitable for multi-cavity and modular mold systems

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

Applications & Industries

These SKD61 nitrided core pins and inserts 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 injection mold assemblies

They are especially suitable for applications requiring thermal stability, surface durability, and repeatable mold performance.

Mold Structure & Design Description

SKD61 core pins and inserts are installed on the core side of injection and die casting molds to form internal product features and support mold structure.
Key design considerations include:

• Accurate pin and insert geometry based on mold layout

• Proper fit and alignment with surrounding cavity components

• Structural strength to withstand injection pressure and thermal load

• Compatibility with replaceable and multi-cavity mold designs

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

Manufacturing Capability & CNC Machining

Senlan Precision manufactures SKD61 nitrided mold components using advanced CNC machining and precision 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 for core pins and inserts

• Stable dimensional control before and after heat treatment

• Consistent surface finish prior to nitriding

• Reliable repeatability across production batches

Nitriding is applied after machining to improve surface hardness while maintaining core toughness.
