Nitrided Jet Cooling Core Pins | ±pm$0.01mm Concentricity HPDC Mold Parts

Product Overview

Nitrided jet cooling core pins are precision die casting mold components designed for injection mold applications requiring efficient internal cooling, high wear resistance, and strict concentricity control. Manufactured through precision CNC machining, controlled heat treatment, and nitriding processes, these core pins achieve concentricity up to 0.01 mm. All parts are custom produced strictly according to customer drawings and technical specifications.

Key Features & Technical Advantages

• Nitriding surface treatment to improve wear resistance and service life

• Concentricity control up to 0.01 mm for stable mold alignment

• Internal cooling channel accuracy for consistent thermal performance

• Stable geometry under high pressure and thermal cycling

• Suitable for multi-cavity and high-cycle mold systems

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

Applications & Industries

These nitrided jet cooling core pins 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

• Precision die casting molds requiring active cooling control

They are especially suitable for applications requiring thermal efficiency, dimensional stability, and repeatable molding performance.

Mold Structure & Design Description

Jet cooling core pins are installed on the core side of injection or die casting molds and incorporate internal cooling channels to regulate mold temperature.
Key design considerations include:

• Precise concentricity between outer geometry and internal cooling channels

• Accurate jet outlet positioning for effective heat transfer

• Proper sealing and alignment within the mold structure

• Structural strength to withstand injection pressure and thermal stress

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