Gibraltar EY6429-G Die Mold Ejector Sleeve 5/32 X 1/4 in

Product Description

The GIBRALTAR EY6429-G is a nitride coated die steel ejector sleeve designed for use in die and mold tooling assemblies. This sleeve features a 5/32 inch inside diameter and 1/4 inch outside diameter, with a 5 inch overall length and a 50mm pin length. The head measures 7/16 inch in diameter and 3/16 inch in height with a 45-degree chamfer. Nitride coating increases surface hardness and wear resistance, extending service life in high-cycle ejection applications. Toolmakers and mold maintenance technicians install this component as part of the ejector system that pushes finished parts from a mold cavity.

This ejector sleeve is suited for use in injection molds, die cast tooling, and compression mold assemblies where a guided ejector pin must pass through a close-tolerance sleeve. It is appropriate for both production tooling and toolroom repair work. The compact head geometry and chamfered entry allow for straightforward installation into standard ejector plate setups. Applications span automotive, consumer goods, and industrial molding operations where consistent ejector performance and dimensional accuracy are required.

Key Features

• 5/32 inch inside diameter and 1/4 inch outside diameter for precise pin-to-sleeve fit
• 5 inch overall length with 50mm pin length for standard mold stack depths
• Nitride coated die steel construction for improved surface hardness and wear resistance
• 7/16 inch head diameter with 3/16 inch head height for positive seating in ejector plates
• 45-degree chamfer angle for guided entry and reduced installation effort
• Sold individually, suitable for single-component toolroom replacement

Compatibility

Designed as an OEM-style replacement ejector sleeve for die and injection mold tooling assemblies requiring a 5/32 inch inside diameter, 1/4 inch outside diameter sleeve with a 5 inch overall length.

Installation Notes

Installation is performed by toolmakers or mold maintenance technicians during scheduled mold servicing or component replacement. The mold must be fully cooled, de-energized, and removed from the press before ejector plate disassembly begins. Ensure the ejector pin and sleeve bore are clean and free of burrs before seating the sleeve. Verify head seating depth and plate clearance before returning the mold to production.
