Gibraltar EY6457-G Die Mold Ejector Sleeve Nitride Steel

Product Description

The GIBRALTAR EY6457-G is a nitride coated die steel ejector sleeve designed for use in die mold tooling applications. It features a 0.25 inch inside diameter, a 0.375 inch outside diameter, and an overall length of 10 inches. The sleeve is manufactured from die steel with a nitride coating applied for increased surface hardness and wear resistance. This component is installed by toolmakers, mold technicians, and die maintenance professionals working on injection mold and die cast tooling systems. The head diameter measures 0.625 inches with a head height of 0.25 inches, providing a positive retention shoulder during ejection cycles.

Ejector sleeves are used in plastic injection molds and die casting tooling to eject cylindrical cores or pins from the mold cavity during the part release cycle. The EY6457-G suits applications requiring a precision-fit sleeve around a round ejector pin where a hollow ejector element is necessary. The 45-degree chamfer angle and 3/64 inch chamfer length facilitate alignment during assembly and reduce edge interference. A 1/32 inch corner radius on the head minimizes stress concentration at the shoulder transition. This sleeve is suited for both new tooling builds and replacement of worn components in existing mold bases.

Key Features

• Nitride coated die steel construction for extended wear life and surface hardness
• 0.25 inch inside diameter and 0.375 inch outside diameter for precision fitment around ejector pins
• 10 inch overall length accommodates deeper mold stack configurations
• 0.625 inch head diameter with 0.25 inch head height provides positive ejector plate retention
• 45-degree chamfer angle with 3/64 inch chamfer length eases assembly alignment
• 1/32 inch corner radius reduces stress concentration at the head-to-body transition

Compatibility

Designed as an OEM-style replacement or new-build component for die mold and injection mold tooling systems requiring a hollow ejector sleeve around a round ejector pin.

Installation Notes

Ejector sleeves are installed by qualified toolmakers or mold technicians. Always ensure the mold is fully de-energized, cooled, and secured in a press or fixture before disassembling the ejector system. Verify inside diameter clearance against the mating ejector pin to confirm proper fit and free sliding action before final assembly. Follow the tooling manufacturer and applicable shop safety standards when handling precision ground components.
