Gibraltar EY6438-G Die Mold Ejector Sleeve Nitride Die Steel

Product Description

The GIBRALTAR EY6438-G is a die mold ejector sleeve designed for use in injection mold tooling and die casting applications. It features a 0.1875-inch (3/16 inch) inside diameter and a 0.3125-inch (5/16 inch) outside diameter, with an overall length of 7 inches. Constructed from nitride coated die steel, this sleeve delivers the surface hardness and wear resistance required for high-cycle ejection systems. The 45-degree chamfer angle on the sleeve end aids in alignment and reduces edge stress during repeated actuation. Toolmakers, mold maintenance technicians, and die shop professionals install this component as a precision fit within ejector plate assemblies.

This ejector sleeve is suited for plastic injection molds and die casting tooling where a hollow ejector element is needed to eject parts around a core pin. The 7-inch overall length accommodates standard mold base configurations requiring moderate ejector stroke depth. The nitride coating provides a hard, low-friction surface that extends service life in production environments with high ejection cycle counts. It is appropriate for both new mold builds and replacement of worn ejector sleeves during mold maintenance.

Key Features

• 0.1875-inch inside diameter and 0.3125-inch outside diameter for precise fit over core pins
• 7-inch overall length suits standard mold base ejector plate configurations
• Nitride coated die steel construction provides surface hardness and wear resistance
• 45-degree chamfer angle aids alignment and reduces stress concentration at the sleeve end
• Single-piece quantity packaging suitable for maintenance replacement or prototype builds

Compatibility

Designed as an OEM-style replacement or new-build component for die mold ejector plate assemblies requiring a hollow ejector sleeve with a 0.1875-inch inside diameter and 0.3125-inch outside diameter.

Installation Notes

Installation is performed by toolmakers or mold maintenance technicians with the mold fully de-energized, cooled, and removed from the press. The sleeve must be fitted over the corresponding core pin with clearances verified per mold design specifications before assembly into the ejector plate. Ensure the ejector plate bores are clean and free of burrs prior to insertion. Follow applicable shop safety and lockout/tagout procedures when servicing mold tooling.
