H13 (SKH61) Core Pins | Mirror Polished Precision Parts for Medical Molds

Product Overview

SKH61 mould core pins are precision-manufactured mold components designed for plastic medical injection molds. Using controlled CNC machining and polishing processes, these core pins provide stable dimensional accuracy, smooth surface finish, and reliable performance for medical mold parts requiring consistent geometry and controlled demolding behavior in high-cycle production environments.

Key Features & Technical Advantages

• Manufactured from SKH61 hot-work tool steel

• Precision CNC machining with controlled polishing process

• Stable dimensional accuracy and concentricity

• Smooth surface finish for medical mold applications

• Suitable for high-cavity and high-cycle injection molds

• Custom dimensions manufactured strictly to drawings

Applications & Industry Use

• Medical plastic injection molds

• Disposable medical components and housings

• Laboratory and healthcare-related plastic parts

• Multi-cavity medical mold tooling systems

Mold Structure & Design Description

The mould core pin forms critical internal or functional geometries in medical injection mold parts. Proper polishing reduces surface friction and improves resin flow consistency during injection and demolding. All dimensions, tolerances, and interface features are manufactured according to customer-approved drawings to ensure accurate fit within existing mold assemblies.
