It features a 1-inch shank diameter with a 5-29\/32-inch shank length and a 2-inch head diameter, giving an overall length of 6-25\/32 inches. The bushing is machined from steel for durability under repeated thermal and mechanical cycling. The 7\/32-inch hole diameter channels molten material from the injection nozzle into the mold cavity. Mold builders, toolmakers, and die maintenance technicians are the primary installers of this component.\u003c\/p\u003e\u003cp\u003eThis sprue bushing is suited for use in injection mold bases and die cast tooling where a Series B configuration is required. The 3\/4-inch corner radius, 3\/16-inch cavity depth, and 7\/8-inch head height are dimensioned to meet standard mold base geometry. It is appropriate for both new mold builds and replacement applications in production tooling environments. The single-piece steel construction supports high-cycle production use.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1-inch shank diameter and 5-29\/32-inch shank length for standard Series B mold base fitment\u003c\/li\u003e\n\u003cli\u003e2-inch head diameter with 7\/8-inch head height for proper seating in the mold plate\u003c\/li\u003e\n\u003cli\u003e7\/32-inch hole diameter for controlled sprue channel flow\u003c\/li\u003e\n\u003cli\u003e3\/4-inch corner radius and 3\/16-inch cavity depth machined to Series B specification\u003c\/li\u003e\n\u003cli\u003eSteel construction for resistance to thermal fatigue and mechanical wear\u003c\/li\u003e\n\u003cli\u003eOverall length of 6-25\/32 inches for drop-in replacement compatibility\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 B die mold and injection mold tooling applications requiring a 1-inch shank diameter sprue bushing.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified toolmakers or mold maintenance technicians. The mold must be fully de-energized, cooled, and depressurized before removing or installing any sprue bushing. Ensure the mold plate bore is clean and free of debris before seating the bushing. Verify dimensional fitment against the mold base specification sheet before final assembly.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 5-29\/32 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: 7\/8 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 6-25\/32 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 7\/32 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCavity Depth\u003c\/strong\u003e: 3\/16 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 3\/4 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Series B\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.05 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: BW8642-G\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GIBRALTAR","offers":[{"title":"Default Title","offer_id":51699239289138,"sku":"BW8642-G","price":451.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8c7eb1e9742b1e3eac1ffa4dd770a3e7_4f8d11e3-be92-44f6-836c-4d22e6bdcd2d.jpg?v=1788373976","url":"https:\/\/voomisupply.com\/products\/gibraltar-bw8642-g-die-mold-sprue-bushing-series-b","provider":"Voomi Supply","version":"1.0","type":"link"}
