Nitrided H13 (SKD61) Flat Ejector Pins | Precision Blade Pins for Die Casting

Product Overview

SKD high speed steel nitrided flat core ejector pins are precision mould components designed for demanding mould systems requiring high surface hardness, wear resistance, and dimensional stability. Manufactured strictly to customer drawings, these ejector pins are suitable for high-cycle mould operations where controlled ejection performance and long service life are critical.

Core Features & Technical Advantages

• Built-to-Print manufacturing based on customer specifications

• SKD high speed steel for thermal stability and strength

• Gas or salt bath nitriding for enhanced surface hardness

• Flat core geometry for controlled ejection and load distribution

• High wear resistance under repetitive mould cycles

• Stable dimensional accuracy after heat treatment

Applications & Industry Use

These nitrided flat core ejector pins are commonly used in:

• Injection mould systems for packaging components

• Cap, closure, and sealing part moulds

• Medical mould tooling with strict repeatability requirements

• Multi-cavity moulds requiring consistent ejection behavior

• OEM mould projects for export markets

All applications are limited to industrial mould tooling systems.

Mould Structure & Design Description

Within the mould structure, the flat core ejector pin serves as:

• A functional ejection element assisting part release

• A load-bearing component distributing ejection force evenly

• A precision-guided part interacting with ejector plates and bushings

Key engineering considerations include:

• Flat surface geometry and parallelism

• Nitrided layer depth and hardness uniformity

• Straightness and concentric alignment

• Fit accuracy within ejector guide systems
