Gibraltar EY6489-G Die Mold Ejector Sleeve 6 in Oal

Product Description

The GIBRALTAR EY6489-G is a nitride coated die steel ejector sleeve designed for use in die mold tooling applications. The sleeve features a 0.5 inch inside diameter and an 0.6875 inch outside diameter, with an overall length of 6 inches. It includes a 0.9375 inch head diameter, a 0.25 inch head height, a 45-degree chamfer angle, a 3/64 inch chamfer length, and a 1/32 inch corner radius. The nitride coating provides enhanced surface hardness and wear resistance, extending service life in high-cycle mold environments. Installed by tool and die makers or mold maintenance technicians in precision tooling operations.

This ejector sleeve is suited for die mold and injection mold tooling setups where precise ejection of cylindrical cores or pins is required. It fits standard ejector plate assemblies and is appropriate for both production and maintenance tooling applications. The compact head geometry and chamfered lead-in support accurate seating and repeatable part ejection in close-tolerance mold bases.

Key Features

• Nitride coated die steel construction for increased surface hardness and extended wear life
• 0.5 inch inside diameter with 0.6875 inch outside diameter for precise sleeve-to-pin clearance
• 6 inch overall length accommodates standard mold plate stack heights
• 45-degree chamfer angle with 3/64 inch chamfer length for clean lead-in and seating
• 0.9375 inch head diameter and 0.25 inch head height for positive retention in ejector plates
• 1/32 inch corner radius reduces stress concentration at the head-to-body transition

Compatibility

Designed as an OEM-style replacement or direct-fit component for standard ejector plate assemblies in die mold and injection mold tooling applications requiring a 0.5 inch inside diameter ejector sleeve.

Installation Notes

Installation is performed by qualified tool and die technicians or mold maintenance personnel. The mold should be fully cooled, de-pressurized, and locked out before any ejector system service. Verify sleeve-to-pin clearance and ejector plate bore dimensions before installation to ensure proper fit and function. Do not force the sleeve into an undersized bore, as this may damage the nitride coating or distort the sleeve geometry.
