Overview

The Customizable Long Service Life Precise Nitrided Straight KO Pin Ejector Pin is a high-performance solution designed for die casting applications, combining precision engineering with exceptional durability. Engineered with a nitrided surface and customizable dimensions, this ejector pin ensures reliable part ejection while minimizing wear, making it ideal for high-volume production of complex metal components. Its robust design and material optimization address the critical needs of die casting molds, where precision and longevity are paramount.

Features

Nitrided Surface Treatment: Hardness up to HV900-1000 via gas nitriding, providing 3x wear resistance compared to standard ejector pins and reducing maintenance frequency by 40%.

Precision Manufacturing: CNC-machined from SKD11 tool steel (HRC58-62), achieving dimensional accuracy of ±0.002mm and straightness ≤0.01mm/m for seamless mold integration.

Customization Flexibility: Available in diameters 3-50mm and lengths 50-500mm, with optional coatings (TiN, DLC) for specific corrosion or heat resistance requirements.

Load-Bearing Design: Optimized shoulder geometry distributes ejection force evenly, supporting up to 50kN dynamic load without deformation in high-pressure die casting (HPDC) applications.

Surface Finish: Polished to Ra0.2μm on working surfaces, reducing friction and preventing metal adhesion during part ejection.

Application

Ideal for die casting molds producing complex metal parts, this ejector pin excels in:

Automotive Components: Ejection of aluminum alloy engine blocks, transmission cases, and suspension parts in high-pressure die casting lines.

Aerospace Castings: Precision ejection of magnesium alloy components with tight tolerances for aircraft interiors and structural parts.

Consumer Electronics: Gentle ejection of thin-walled zinc alloy casings for smartphones, laptops, and wearables, minimizing surface defects.
