Gibraltar EY6459-G Die Mold Ejector Sleeve 12in Nitride

Product Description

The GIBRALTAR EY6459-G is a nitride coated die steel ejector sleeve used in die mold tooling applications. It features a 0.25 inch inside diameter and a 0.375 inch outside diameter, with an overall length of 12 inches. The sleeve is manufactured from die steel and finished with a nitride coating to improve surface hardness and extend service life under the repeated impact and wear conditions typical of mold ejection cycles. A 45-degree chamfer aids alignment and part ejection. Toolmakers and moldmakers install this component as part of the ejector system in injection molds, compression molds, and die casting tooling.

This ejector sleeve is suited for use in production tooling environments where consistent ejection geometry and dimensional accuracy are critical. The 0.625 inch head diameter and 0.25 inch head height allow it to seat properly within standard ejector plate configurations. The 3/64 inch chamfer length and 1/32 inch corner radius are consistent with standard die mold ejector sleeve geometry. This part is sold individually and is appropriate for new tooling builds as well as replacement of worn or damaged sleeves during mold maintenance.

Key Features

• Nitride coated die steel construction for improved surface hardness and wear resistance
• 0.25 inch inside diameter and 0.375 inch outside diameter for precise fitment
• 12 inch overall length suits deep-draw mold configurations
• 45-degree chamfer angle aids part ejection and component alignment
• 0.625 inch head diameter with 0.25 inch head height for standard ejector plate seating
• 1/32 inch corner radius and 3/64 inch chamfer length per standard sleeve geometry

Compatibility

Designed as a standard-geometry ejector sleeve for use in die molds and injection mold tooling requiring a 0.25 inch inside diameter and 0.375 inch outside diameter sleeve with a 12 inch overall length.

Installation Notes

Ejector sleeves are installed by moldmakers and tool and die technicians. The mold must be fully de-energized, cooled, and removed from the press before ejector system service begins. Sleeves should be checked for concentricity and free movement within the ejector plate before reassembly. Follow the tooling drawings and applicable shop standards for fit tolerances when pressing or sliding the sleeve into the ejector plate.
