Medical Grade Gas Vent Core Pins | High-Hardness Steel Rubber Tooling Components

Product Overview

High-hardened steel core pins with integrated gas venting are precision mold components designed for medical cavity rubber tooling and injection molds requiring controlled venting, dimensional stability, and wear resistance. Manufactured through precision CNC machining and controlled heat treatment, these core pins support stable cavity filling and reliable demolding. All parts are custom produced strictly according to customer drawings and technical specifications.

Key Features & Technical Advantages

• High-hardened tool steel for wear resistance and long service life

• Integrated gas vent design to improve air evacuation and filling stability

• Precision CNC machining for accurate pin geometry and vent features

• Stable dimensional performance under repeated molding cycles

• Consistent surface quality for reliable demolding

• Suitable for multi-cavity medical tooling environments

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

Applications & Industries

These core pins are widely used in:

• Medical cavity rubber tooling

• Injection molds for medical packaging components

• Precision molds requiring controlled venting

• Multi-cavity molds with strict quality requirements

They are particularly suitable for applications where gas evacuation, surface integrity, and repeatable molding performance are critical.

Mold Structure & Design Description

High-hardened core pins with gas vents are installed on the core side of molds to form internal features while allowing trapped air or gas to escape during filling.
Key design considerations include:

• Accurate pin geometry and vent channel positioning

• Controlled vent size to balance air release and material flow

• Proper alignment with cavity inserts

• Structural stability under molding pressure

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