The sleeve measures 7\/16 inches inside diameter, 5\/8 inches outside diameter, and 4 inches overall length, with a 7\/8 inches head diameter and 1\/4 inches head height. The nitride coating provides increased surface hardness and wear resistance, extending service life under the high-cycle, high-pressure conditions typical of production molding environments. Licensed toolmakers and mold technicians install this component as part of the ejector assembly in injection or compression mold tooling.\u003c\/p\u003e\n\u003cp\u003eThis ejector sleeve is suited for use in die mold ejector systems where controlled part release is required. The 45-degree chamfer angle and 3\/64 inches chamfer length aid alignment during assembly and reduce edge wear at the mating bore. The 1\/32 inches corner radius minimizes stress concentration at the head transition. Typical installations are found in production tooling shops and mold maintenance operations servicing plastic injection molds, die cast tooling, and similar precision mold assemblies.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNitride coated die steel construction for enhanced surface hardness and wear resistance\u003c\/li\u003e\n  \u003cli\u003e7\/16 inches inside diameter x 5\/8 inches outside diameter for precise bore fit\u003c\/li\u003e\n  \u003cli\u003e4 inches overall length with 7\/8 inches head diameter and 1\/4 inches head height\u003c\/li\u003e\n  \u003cli\u003e45-degree chamfer angle with 3\/64 inches chamfer length for guided assembly\u003c\/li\u003e\n  \u003cli\u003e1\/32 inches corner radius to reduce stress concentration at head transition\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-fit component for die mold ejector assemblies requiring a 7\/16 inches ID x 5\/8 inches OD nitride coated ejector sleeve.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified toolmakers or mold technicians. The mold must be fully de-energized, depressurized, and cooled before ejector system disassembly. Confirm bore alignment and clearance tolerances before seating the sleeve to avoid binding or galling. Follow the mold manufacturer's assembly procedures and applicable shop safety standards during all ejector plate work.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Inside Diameter\u003c\/strong\u003e: 7\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Outside Diameter\u003c\/strong\u003e: 5\/8 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\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Height\u003c\/strong\u003e: 1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer Angle\u003c\/strong\u003e: 45 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer Length\u003c\/strong\u003e: 3\/64 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1\/32 inches\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: 0.26 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: EY6478-G\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GIBRALTAR","offers":[{"title":"Default Title","offer_id":51716554031410,"sku":"EY6478-G","price":84.4,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/975addce0577f8571beb5d5824f301aa_7f51c43f-bcb8-4a5b-820e-237145d21fbd.jpg?v=1788527768","url":"https:\/\/voomisupply.com\/products\/gibraltar-ey6478-g-die-mold-ejector-sleeve-7-16x5-8-in","provider":"Voomi Supply","version":"1.0","type":"link"}
