With a 0.1875-inch (3\/16 inch) inside diameter and a 0.3125-inch (5\/16 inch) outside diameter, this sleeve provides precise dimensional control for ejector pin guidance and part ejection in injection mold and die cast assemblies. The overall length of 8 inches accommodates standard mold base configurations, and the nitride coating improves surface hardness and wear resistance over untreated steel. This component is installed and serviced by toolmakers, mold builders, and maintenance technicians working on production tooling.\u003c\/p\u003e\n\u003cp\u003eThis ejector sleeve is suited for die mold and injection mold tooling where a hollow sleeve must surround an ejector pin to push a formed part off a core. The 45-degree chamfer angle on the sleeve aids in alignment during assembly and reduces the risk of galling at the mold parting line. It is applicable in both prototype and production mold bases requiring close-tolerance ejector components. The 98-millimeter pin length spec is a reference dimension for mating ejector pin selection.\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 extended service life\u003c\/li\u003e\n  \u003cli\u003e0.1875-inch inside diameter and 0.3125-inch outside diameter for close-tolerance ejector pin fit\u003c\/li\u003e\n  \u003cli\u003e8-inch overall length suits standard and deep mold base configurations\u003c\/li\u003e\n  \u003cli\u003e45-degree chamfer angle assists assembly alignment and reduces edge loading\u003c\/li\u003e\n  \u003cli\u003eSingle-piece quantity with no minimum order requirement beyond one unit\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct tooling component for die mold and injection mold assemblies requiring a 0.1875-inch ID by 0.3125-inch OD ejector sleeve with an 8-inch overall length.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eEjector sleeves are installed by qualified toolmakers or mold maintenance technicians. Before replacing or installing this sleeve, the mold must be fully de-energized, cooled, and safely supported in a press or fixture. Verify that the mating ejector pin diameter matches the sleeve inside diameter before pressing the assembly together to avoid damage to either component. Follow the mold manufacturer's tolerancing and fit specifications when selecting replacement sleeves.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 0.1875 inches (3\/16 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 0.3125 inches (5\/16 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePin Length Reference\u003c\/strong\u003e: 98 millimeters\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: 0.13 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: EY6439-G\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GIBRALTAR","offers":[{"title":"Default Title","offer_id":51713522729266,"sku":"EY6439-G","price":108.93,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8bf767e607e6ced4e8c52b26c8ee3f9f.jpg?v=1788494282","url":"https:\/\/voomisupply.com\/products\/gibraltar-ey6439-g-die-mold-ejector-sleeve-8in-oal","provider":"Voomi Supply","version":"1.0","type":"link"}
