Hot Runner Nozzle Tips & Sprue Bushings | Custom Injection Mold Components

Product Overview

Stainless steel hot runner nozzle tips and sprue bushings are precision mould components designed for stable melt flow control and reliable injection performance in plastic injection moulds. These parts are manufactured for high-temperature operation, consistent flow balance, and long service life, supporting high-cavity and high-speed moulding applications across packaging and medical industries.

Key Features & Technical Advantages

• Manufactured from stainless steel (SS) for thermal stability and wear resistance

• Designed for hot runner and sprue feeding systems

• Stable melt flow and reduced pressure loss

• High dimensional accuracy for precise mould integration

• Suitable for high-cavity and continuous production moulds

• Compatible with various hot runner system layouts

• Customized / OEM / Built-to-Print manufacturing

Applications & Industry Use

These hot runner nozzle tips and sprue bushings are widely used in:

• Bottle cap and closure injection moulds

• Packaging moulds requiring balanced melt distribution

• Medical plastic injection moulds with stable process control

• Multi-cavity injection moulds operating at high cycle rates

They are critical components for maintaining injection consistency and moulding efficiency.

Mould Structure & Design Description

In plastic injection mould assemblies, these components are typically applied as:

• Hot runner nozzle tips for direct melt delivery into cavities

• Sprue bushings connecting the injection unit and runner system

• Precision-installed parts controlling melt entry position and flow

• Replaceable wear components in hot runner systems

All parts are produced strictly according to customer drawings, including geometry, interface dimensions, and installation requirements.
