Gibraltar EY6522-G Die Mold Ejector Sleeve 12 Inch

Product Description

The GIBRALTAR EY6522-G is a nitride coated die steel ejector sleeve designed for use in die mold tooling applications. This precision sleeve features a 3/4 inch inside diameter, 1 inch outside diameter, and a 12 inch overall length. The head measures 1-1/4 inches in diameter with a 1/4 inch head height. A 45-degree chamfer angle with a 3/64 inch chamfer length and a 1/32 inch corner radius are incorporated into the design to facilitate clean part ejection and reduce wear at the mold interface. Installed by toolmakers and mold technicians, this sleeve is built to withstand the repeated mechanical stress of high-cycle injection and die casting operations.

This ejector sleeve is suited for die mold and injection mold tooling setups where precise, repeatable ejection of cylindrical or tubular part features is required. The nitride coating extends surface hardness and wear resistance, making it appropriate for demanding production environments. It is a direct-install component in mold bases where standard ejector sleeve configurations are specified by the mold design.

Key Features

• Nitride coated die steel construction for enhanced surface hardness and wear resistance
• 3/4 inch inside diameter and 1 inch outside diameter for precise sleeve fit in standard mold bases
• 12 inch overall length suitable for deep-draw or extended ejection stroke requirements
• 1-1/4 inch head diameter with 1/4 inch head height for positive seating against the ejector plate
• 45-degree chamfer angle with 3/64 inch chamfer length eases alignment and reduces edge stress
• 1/32 inch corner radius minimizes stress concentration at the head-to-body transition

Compatibility

Designed as an OEM-style replacement or direct-install component for die mold and injection mold tooling applications requiring a 3/4 inch ID by 1 inch OD ejector sleeve with a 12 inch overall length.

Installation Notes

Ejector sleeves are installed by toolmakers or mold maintenance technicians during mold build or preventive maintenance cycles. The mold should be fully powered down and all hydraulic or pneumatic pressure relieved before disassembly. Confirm bore alignment and ejector plate clearance before seating the sleeve to avoid binding during operation. Consult the mold design drawings for proper orientation and seating depth.
