1.2344 Steel Core Pins & Sleeves | High Toughness Parts for Pen Moulds

Product Overview

1.2344 material mold core pins and sleeves are high-toughness mould components designed for plastic injection moulds requiring dimensional stability and long service life. Manufactured through precision CNC machining and controlled heat treatment, these components provide reliable performance in high-cycle moulding environments. All core pins and sleeves are produced strictly according to customer drawings and technical specifications.

Key Features & Technical Advantages

• Manufactured from 1.2344 hot-work tool steel

• High toughness with good resistance to thermal fatigue

• Stable hardness distribution after heat treatment

• Excellent dimensional consistency for precision moulds

• Smooth surface finish to reduce wear and friction

• Suitable for long-term and multi-cavity mould operation

• Custom design, OEM supply, and Built-to-Print production supported

Applications & Industry Use

• Bottle cap and closure injection moulds

• Packaging container and thin-wall mould systems

• Precision daily-use product moulds

Mould Structure & Design Description

Core pins and sleeves are critical functional components that directly define product geometry and mould durability. In mould structures, they are used to:

• Form internal or hollow features

• Maintain accurate alignment in repeated cycles

• Withstand thermal and mechanical stress during injection

Material selection, fit tolerance, and surface condition are customized based on mould layout, cavity count, and expected service life.

Manufacturing Capability & CNC Machining Capacity

• CNC turning and milling for core geometry

• Precision grinding for diameter and concentricity control

• Controlled heat treatment for toughness optimization

• Surface finishing for wear reduction

• In-process and final dimensional inspection

• Capability for both small batch and volume production

Custom Development & OEM Cooperation Process

1. Customer drawing or sample evaluation
