Gibraltar EY6441-G Die Mold Ejector Sleeve Nitride Coated

Product Description

The GIBRALTAR EY6441-G is a nitride coated die steel ejector sleeve designed for use in die mold and injection mold tooling applications. It features a 0.1875 inch inside diameter, a 0.3125 inch outside diameter, and an overall length of 10 inches, with a pin length of 158 millimeters. The 45-degree chamfer angle on the sleeve supports consistent, low-friction ejection of molded parts. Constructed from die steel with a nitride surface treatment, this sleeve delivers improved wear resistance and surface hardness under repetitive high-cycle mold operation. It is installed by toolmakers and mold technicians as part of the ejector system in plastic injection or die casting molds.

This ejector sleeve is suited for precision mold tooling in industrial manufacturing environments. It fits into standard ejector plate assemblies where a hollow sleeve configuration is required to eject parts around a core pin. The 10 inch overall length accommodates deeper mold configurations. With a body outside diameter of 0.3125 inches and a 0.1875 inch bore, it is sized for fine-pitch ejector positions in multi-cavity or single-cavity tooling setups. The nitride coating makes it appropriate for applications involving abrasive resins or extended production runs where uncoated steel would wear prematurely.

Key Features

• Nitride coated die steel construction for increased surface hardness and wear resistance
• 0.1875 inch inside diameter for precise core pin clearance
• 0.3125 inch outside diameter body for standard ejector bore fitment
• 10 inch overall length supports deeper mold tooling configurations
• 45-degree chamfer angle aids part ejection and sleeve seating
• 158 millimeter pin length for dimensional reference during assembly

Compatibility

Designed as an OEM-style replacement or direct-fit component for die mold and injection mold ejector plate assemblies requiring a 0.1875 inch ID by 0.3125 inch OD sleeve profile.

Installation Notes

Installation is performed by qualified toolmakers or mold technicians. Always power down and de-energize the molding machine and release any hydraulic or pneumatic pressure before accessing the ejector system. Confirm bore alignment and sleeve fit against the ejector plate and core pin before pressing the sleeve into position. Do not modify the sleeve geometry, as alterations to the chamfer or bore may affect ejection performance and part quality.
