The sleeve features a 5\/32 inch inside diameter and a 1\/4 inch outside diameter, with an overall length of 4 inches. The head diameter measures 7\/16 inch with a head height of 3\/16 inch and a 45-degree chamfer angle. Nitride coating improves surface hardness and wear resistance, extending service life under the repetitive loading cycles common in production molding environments. This component weighs approximately 0.07 pounds. Toolmakers and mold technicians are the primary installers of this type of precision sleeve.\u003c\/p\u003e\n\u003cp\u003eEjector sleeves of this type are used in injection mold and die cast tooling to eject cylindrical or round-core features from a mold cavity. The EY6428-G suits applications where a close-tolerance sleeve is needed around a core pin to push molded parts free without marking or distorting the part surface. The 4 inch overall length and 125 mm pin length accommodate standard mold plate stack heights in a range of production tooling configurations. This sleeve is suited to both prototype and production mold builds where consistent ejection force distribution is required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNitride coated die steel construction for improved surface hardness and wear resistance\u003c\/li\u003e\n  \u003cli\u003e5\/32 inch inside diameter with 1\/4 inch outside diameter for close-tolerance fitment around core pins\u003c\/li\u003e\n  \u003cli\u003e7\/16 inch head diameter with 3\/16 inch head height for positive seating in ejector retainer plates\u003c\/li\u003e\n  \u003cli\u003e45-degree chamfer angle for guided assembly and reduced installation stress\u003c\/li\u003e\n  \u003cli\u003e4 inch overall length suitable for standard mold plate stack configurations\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.07 pounds for easy handling during mold build and maintenance\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or original-build component for die mold and injection mold ejector systems requiring a 5\/32 inch ID by 1\/4 inch OD sleeve with a 4 inch overall length.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified toolmakers or mold technicians. Ensure the mold is fully de-energized, cooled, and safely secured in a press or work fixture before ejector plate disassembly. Verify core pin diameter and ejector retainer plate bore dimensions against the sleeve specifications before pressing the sleeve into position. Avoid applying side load or impact force to the sleeve head during installation to prevent deformation of the precision-ground surfaces.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 5\/32 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 7\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Height\u003c\/strong\u003e: 3\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer Angle\u003c\/strong\u003e: 45 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Nitride Coated Die Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.07 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: GIBRALTAR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: EY6428-G\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GIBRALTAR","offers":[{"title":"Default Title","offer_id":51722198876466,"sku":"EY6428-G","price":68.52,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/975addce0577f8571beb5d5824f301aa_7026d207-2805-44d6-b7cc-6ad6daf277c9.jpg?v=1788587233","url":"https:\/\/voomisupply.com\/products\/gibraltar-ey6428-g-die-mold-ejector-sleeve-nitride-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
