HRC 62 Blade Ejector Pins | Precision Ground Mold Components for Injection

Product Overview

Senlan Precision manufactures Grinding Forming Blade Ejector Pins hardened to HRC 62, designed for precise ejection in injection molds requiring high wear resistance and stable edge geometry. Produced strictly Built-to-Print, these blade ejector pins deliver consistent demolding performance in high-cycle, multi-cavity tooling.

Key Features & Advantages

• HRC 62 hardness after controlled heat treatment for superior wear resistance

• Grinding forming process ensures sharp, stable blade profiles and dimensional accuracy

• Excellent straightness and edge consistency for reliable demolding

• High fatigue strength suitable for continuous production cycles

• Custom / OEM manufacturing strictly according to drawings

• Stable replacement compatibility for existing molds

Applications / Industry Use

• Injection molds for bottle caps and closures

• Thin-wall packaging components

• Medical plastic molds requiring precise, clean ejection

• Multi-cavity, high-speed injection molding systems

• Spare or replacement blade ejector pins

Mold Structure & Design Description

Blade ejector pins are used where standard round pins cannot provide sufficient contact or controlled release. The flat blade geometry supports uniform force distribution during ejection, reducing deformation and surface damage to molded parts. High hardness combined with precision grinding ensures dimensional stability and long service life under repeated injection cycles.

Manufacturing Capability & CNC Machining

• Equipment: High-precision machining and grinding systems from MAKINO (Japan) and HARDINGE (USA)
