Gibraltar EY6431-G Die Mold Ejector Sleeve Nitride Die Steel

Product Description

The GIBRALTAR EY6431-G is a nitride coated die steel ejector sleeve designed for use in die mold tooling applications. The sleeve features a 5/32 inch inside diameter and a 1/4 inch outside diameter, with an overall length of 7 inches and a pin length of 110mm. A 7/16 inch head diameter and 3/16 inch head height provide a secure seating surface within the mold plate. The 45-degree chamfer angle aids alignment during assembly. Nitride coating improves surface hardness and wear resistance, extending service life in high-cycle ejection systems. This component is installed by toolmakers and mold technicians working on injection mold or die cast tooling.

Ejector sleeves are used in plastic injection molds and die casting tooling where a sleeve-and-pin arrangement is required to eject cylindrical or tubular part features. This sleeve is suited for precision mold bases in both production and prototype tooling environments. Its nitride coated die steel construction is appropriate for moderate to high production runs where wear resistance and dimensional stability are required.

Key Features

• Nitride coated die steel construction for enhanced surface hardness and wear resistance
• 5/32 inch inside diameter and 1/4 inch outside diameter for precision sleeve-and-pin fit
• 7 inch overall length accommodates standard mold plate stack heights
• 45-degree chamfer angle for guided alignment during installation
• 7/16 inch head diameter with 3/16 inch head height for positive retention in ejector plate
• 110mm pin length for consistent ejection stroke depth

Compatibility

Designed as an OEM-style replacement or direct-fit component for die mold ejector sleeve applications requiring a 5/32 inch inside diameter and 1/4 inch outside diameter sleeve in standard mold base configurations.

Installation Notes

Ejector sleeves are installed by qualified toolmakers or mold maintenance technicians. Always confirm the mold is fully de-energized, hydraulic pressure is relieved, and the press is locked out before servicing ejector components. Verify bore tolerances in the ejector plate and core side before installation to ensure proper sleeve fit and alignment. Do not force the sleeve into an undersized bore as this may damage the chamfer or alter dimensional tolerances.
