Hardened Sprue Bushings & Locating Rings | Precision Injection Mold Components

Product Overview

Heat Treatment Injection Molded Parts – Distributor Short Sleeve Ring are precision mould components designed for injection mould systems requiring stable alignment, wear resistance, and water-resistant performance. Manufactured by Senlan Precision on a custom / OEM / Built-to-Print basis, these parts are optimized for long-term operation in packaging and medical injection moulds where dimensional stability and durability are critical.

Key Features & Advantages

• Heat-treated steel structure for enhanced hardness and wear resistance

• Water-resistant design suitable for cooling-intensive mould environments

• Stable dimensional accuracy after heat treatment

• Consistent performance in multi-cavity mould systems

• Smooth surface finish to reduce friction and assembly wear

• Designed strictly according to customer drawings (Built-to-Print)

Applications / Industry Use

• Injection mould distributor systems

• Bottle and cap mould assemblies

• Packaging moulds with cooling circulation

• Medical injection mould components

• Precision mould alignment and support structures

Mould Structure & Design Description

The distributor short sleeve ring is typically used as a functional interface component within injection mould assemblies, supporting alignment and fluid-isolated operation. After precision machining, controlled heat treatment is applied to improve hardness and service life while maintaining dimensional stability. The water-resistant design ensures reliable operation in moulds with intensive cooling channels or humid production environments.

Manufacturing Capability & CNC Machining

Senlan Precision applies controlled machining and thermal processes to ensure repeatable quality:

• CNC turning for concentric sleeve geometries

• CNC milling for functional interfaces

• Precision grinding for tolerance-critical surfaces

• Controlled heat treatment to specified hardness ranges

• Final surface finishing for assembly reliability

Advanced machining capacity, including Japanese MAKINO and American HARDINGE equipment, supports stable production quality for export-oriented mould components.
