HSS Precision Core Pins | 0.005mm Perpendicularity for Medical Molds

Product Overview

HSS material precision injection mold core pins manufactured for high-accuracy medical plastic tooling applications. These core pins are produced with controlled verticality within 0.005 mm, ensuring stable alignment, repeatable molding performance, and consistent part quality. All components are manufactured strictly according to customer drawings under Built-to-Print and OEM requirements.

Key Features & Technical Advantages

• High Speed Steel (HSS) material for wear resistance and dimensional stability

• Verticality controlled within ≤ 0.005 mm

• Precision cylindrical grinding and fine machining processes

• Stable performance in high-cycle injection molding environments

• Suitable for tight-tolerance medical mold assemblies

• Fully customized dimensions based on customer drawings

Applications & Industry Use

• Medical plastic injection molds
