Gibraltar EY6455-G Die Mold Ejector Sleeve Nitride Die Steel

Product Description

The GIBRALTAR EY6455-G is a nitride coated die steel ejector sleeve designed for use in die mold and injection mold tooling applications. It features a 0.25 inch inside diameter, a 0.375 inch outside diameter, and an overall length of 8 inches. The 45-degree chamfer angle on the sleeve end simplifies seating and alignment during assembly. Nitride coating increases surface hardness and wear resistance, extending service life in high-cycle mold ejection systems. This part weighs approximately 0.19 pounds and is supplied individually. Installation is handled by toolmakers, mold setters, and precision machining technicians working with ejector pin and sleeve assemblies.

The EY6455-G is suited for injection mold tooling, die casting molds, and precision machining setups that require a hardened sleeve to guide and support an ejector pin through the mold plate. The 8 inch overall length accommodates deeper mold bases, and the nitride coated die steel construction handles the repetitive mechanical stress and heat cycling typical of production mold environments. This sleeve is sold and installed as a single unit and is appropriate for both prototype tooling and production mold maintenance applications.

Key Features

• Nitride coating provides increased surface hardness and wear resistance for extended service life
• 0.25 inch inside diameter and 0.375 inch outside diameter for precise pin-to-sleeve fit
• 8 inch overall length accommodates deep mold base configurations
• 45-degree chamfer angle for easier assembly and alignment
• Die steel construction withstands high-cycle mechanical and thermal stress in mold tooling
• Single-unit packaging for individual replacement or tooling builds

Compatibility

Designed as an OEM-style replacement or new-build component for die mold and injection mold ejector systems requiring a 0.25 inch ID by 0.375 inch OD hardened ejector sleeve with an 8 inch overall length.

Installation Notes

Installation is performed by qualified toolmakers or mold technicians. The mold press or die casting machine must be fully de-energized and locked out before any ejector system maintenance is performed. Sleeves should be inspected for proper bore clearance with the mating ejector pin before final assembly. Forced installation that distorts the sleeve bore will accelerate wear and compromise ejection performance.
