Gibraltar EY6446-G Die Mold Ejector Sleeve Nitride Die Steel

Product Description

The GIBRALTAR EY6446-G is a nitride coated die steel ejector sleeve designed for die mold tooling applications. It features a 7/32 inch inside diameter and an 11/32 inch outside diameter, with an overall length of 6 inches and a pin length of 158 millimeters. The head measures 9/16 inch in diameter with a 1/4 inch head height and a 45-degree chamfer angle. This sleeve is used to eject molded parts from a die or mold cavity during production cycles. Installation is performed by toolmakers and mold technicians working in precision manufacturing environments.

The EY6446-G is suited for use in die casting and injection mold tooling setups where precision ejection is required. The nitride coating provides increased surface hardness and wear resistance, making it appropriate for higher-cycle production tooling. It is a single-piece sleeve sold individually and is compatible with standard ejector plate assemblies that accept the specified head and body dimensions.

Key Features

• Nitride coated die steel construction for improved surface hardness and wear resistance
• 7/32 inch inside diameter accommodates standard ejector pins of the corresponding size
• 45-degree chamfer angle on the head for precise seating in ejector plate bores
• 6 inch overall length with a 158 millimeter pin length for deep mold applications
• 9/16 inch head diameter with 1/4 inch head height for positive retention in ejector plates

Compatibility

Designed as an OEM-style replacement or new-build component for die mold ejector plate assemblies requiring a 7/32 inch inside diameter nitride coated ejector sleeve.

Installation Notes

Ejector sleeves are installed and serviced by toolmakers or mold maintenance technicians. The mold must be fully cooled and all press or clamp pressure must be released before disassembly. Verify bore and pin clearances match the sleeve inside diameter and outside diameter before pressing into the ejector plate. Do not force the sleeve into an undersized bore, as this can crack the nitride coating or distort the sleeve body.
