Gibraltar EY6435-G Die Mold Ejector Sleeve Nitride Die Steel

Product Description

The GIBRALTAR EY6435-G is a nitride coated die steel ejector sleeve designed for use in die mold tooling applications. The sleeve features a 0.1875 inch inside diameter, a 0.3125 inch outside diameter, and an overall length of 4 inches. A 45-degree chamfer angle is machined at the working end, providing clean, consistent contact with the mold component during the ejection cycle. This part is installed by toolmakers, mold technicians, and die maintenance professionals working on injection mold or die casting tooling.

Ejector sleeves of this type are used in precision mold bases and die sets where a cylindrical pin must be guided and supported during part ejection. The compact 0.1875 inch bore suits small-diameter core pins. The nitride surface treatment improves wear resistance and extends service life in high-cycle production tooling environments. This sleeve is sold individually and suits both new tooling builds and maintenance replacement in existing mold assemblies.

Key Features

• Nitride coated die steel construction for improved surface hardness and wear resistance
• 0.1875 inch inside diameter accommodates small-diameter ejector pins
• 0.3125 inch outside diameter for precise bore fitment in mold plates
• 4 inch overall length with 75 mm pin length
• 45-degree chamfer angle for guided, consistent ejection contact
• Sold in single-unit quantity with no minimum order above one piece

Compatibility

Designed as a direct-fit replacement or new-build component for die mold and injection mold tooling assemblies requiring a 0.1875 inch ID by 0.3125 inch OD ejector sleeve.

Installation Notes

Installation is performed by qualified toolmakers or mold maintenance technicians. The mold or die set must be fully de-energized, cooled, and depressurized before any ejector system disassembly. Confirm bore tolerances in the mold plate match the sleeve OD before pressing the sleeve into position. Proper alignment of the sleeve with the ejector pin is critical to prevent galling or premature wear during production cycles.
