Gibraltar EY6456-G Die Mold Ejector Sleeve Nitride Steel

Product Description

The GIBRALTAR EY6456-G is a nitride coated die steel ejector sleeve designed for die mold tooling applications. It features a 0.25 inch inside diameter and 0.375 inch outside diameter body, with an overall length of 9 inches. The sleeve incorporates a 0.625 inch head diameter and 0.25 inch head height for secure seating within the mold assembly. A 45-degree chamfer angle with a 3/64 inch chamfer length and 1/32 inch corner radius ensures clean part ejection and reduced stress concentration at the sleeve tip. Toolmakers and mold technicians install this component as part of the ejector system in injection mold or die casting tooling.

This ejector sleeve is suited for use in precision die mold assemblies where controlled ejection of tubular or cored features is required. The nitride coating improves surface hardness and wear resistance, extending service life in high-cycle mold environments. It is a direct-install component sized for mold bases that accept a 0.375 inch OD ejector sleeve with a 0.625 inch head.

Key Features

• Nitride coated die steel construction for enhanced surface hardness and wear resistance
• 0.25 inch inside diameter and 0.375 inch outside diameter body
• 9 inch overall length suitable for deeper mold stack configurations
• 0.625 inch head diameter with 0.25 inch head height for positive retention
• 45-degree chamfer angle with 3/64 inch chamfer length for clean ejection geometry
• 1/32 inch corner radius reduces stress concentration at sleeve tip

Compatibility

Designed as an OEM-style replacement or direct installation component for die mold and injection mold ejector systems accepting a 0.375 inch OD sleeve body with a 0.625 inch head diameter.

Installation Notes

Installation is performed by qualified toolmakers or mold technicians during mold assembly or maintenance. The mold must be fully de-energized and all hydraulic or pneumatic pressure relieved before ejector system service. Ensure the ejector plate and retainer plate are properly aligned before seating the sleeve to avoid damage to the nitride coating. Consult the mold design drawings for correct sleeve orientation and ejector plate clearance specifications.
