Machined from steel, this Series U bushing features a 0.75 inch shank diameter with a shank length of 2.906 inches and an overall length of 3.781 inches. The 2 inch head diameter provides a stable seating surface within the mold plate. A 0.219 inch hole diameter channels molten material into the mold cavity, while the 0.75 inch corner radius and 0.1875 inch cavity depth support consistent gate geometry. Toolmakers and mold technicians working in production or prototype environments will find this bushing a direct-fit component for standard sprue applications.\u003c\/p\u003e\u003cp\u003eThis sprue bushing is suited for use in injection molding operations where a standardized Series U configuration is required. It seats into the stationary platen or cavity plate and aligns with the injection nozzle to direct resin into the runner system. Typical installations are found in single-cavity and multi-cavity mold bases used in plastics manufacturing environments. The 0.875 inch head height keeps the bushing flush or slightly proud of the mold face depending on plate thickness.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSteel construction for durability under repeated injection cycle loads\u003c\/li\u003e\n\u003cli\u003e0.75 inch shank diameter with 2.906 inch shank length for secure mold plate engagement\u003c\/li\u003e\n\u003cli\u003e2 inch head diameter provides broad seating contact at the mold parting face\u003c\/li\u003e\n\u003cli\u003e0.219 inch hole diameter sized for standard sprue runner entry\u003c\/li\u003e\n\u003cli\u003eSeries U designation for compatibility with common mold base standards\u003c\/li\u003e\n\u003cli\u003e3.781 inch overall length suits standard cavity plate stack heights\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-build component for Series U die mold sprue bushing applications in standard injection mold base assemblies.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by a toolmaker or mold technician during mold assembly or maintenance. The mold should be fully cooled and all hydraulic or mechanical clamping pressure relieved before removing or installing sprue bushings. Press-fit or slip-fit installation should be verified against the mold base bore tolerance before assembly. Consult the mold base manufacturer specifications to confirm correct clearance and seating depth for this bushing series.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 2.906 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Height\u003c\/strong\u003e: 0.875 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 3.781 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.219 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCavity Depth\u003c\/strong\u003e: 0.1875 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Series U\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.07 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: BW8664-G\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GIBRALTAR","offers":[{"title":"Default Title","offer_id":51705771622706,"sku":"BW8664-G","price":226.67,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8c7eb1e9742b1e3eac1ffa4dd770a3e7_cc6d800f-f28a-4b67-a061-d0735d0ce959.jpg?v=1788431036","url":"https:\/\/voomisupply.com\/products\/gibraltar-bw8664-g-die-mold-sprue-bushing-series-u-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
