Constructed from chromium-vanadium steel, it delivers consistent force and fatigue resistance across repeated compression cycles. The spring features a 1-inch hole diameter, a 1\/2-inch rod diameter, and a 1-1\/2-inch free length. At maximum deflection of 0.56 inches, it generates a load of 316 pounds. The D-shaped wire profile maximizes cross-sectional area within the bore, increasing load capacity compared to round-wire springs of equivalent size. This part is typically installed by toolmakers, die setters, and maintenance technicians in industrial manufacturing environments.\u003c\/p\u003e\u003cp\u003eThis die spring is suited for medium-duty press tool and die applications where controlled, repeatable spring force is required. It is color-coded blue to indicate its medium-duty load rating, which simplifies identification and replacement in multi-spring tooling setups. Typical use cases include stripper plates, pressure pads, and core return mechanisms in progressive and compound dies used in automotive, metal fabrication, and general manufacturing operations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eChromium-vanadium steel construction for high fatigue life and consistent load performance\u003c\/li\u003e\n\u003cli\u003eD-shaped wire profile maximizes load capacity within the bore diameter\u003c\/li\u003e\n\u003cli\u003eBlue color coding identifies medium-duty load rating at a glance\u003c\/li\u003e\n\u003cli\u003eMaximum deflection load of 316 pounds at 0.56 inches deflection\u003c\/li\u003e\n\u003cli\u003eMaximum operating deflection of 37.50 percent of free length\u003c\/li\u003e\n\u003cli\u003eMeets ISO 10243, ISO 9001:2015, and NAAMS standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-fit die spring for medium-duty stamping dies, molds, and press tooling that accept a 1-inch bore diameter and 1\/2-inch guide rod.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eDie springs should be installed by qualified toolmakers or die maintenance technicians familiar with press tooling safety procedures. Always de-energize and lock out the press before performing any die or spring service. Ensure the guide rod and bore are free of burrs and debris before seating the spring to prevent uneven loading or premature wear. Do not compress the spring beyond its rated maximum deflection, as exceeding travel-to-solid limits can cause permanent set or fracture.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRod Diameter\u003c\/strong\u003e: 1\/2 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFree Length\u003c\/strong\u003e: 1-1\/2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Deflection Load\u003c\/strong\u003e: 316 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Deflection\u003c\/strong\u003e: 0.56 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Operating Deflection\u003c\/strong\u003e: 37.50 percent\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTravel To Solid Load\u003c\/strong\u003e: 0.60 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDuty Rating\u003c\/strong\u003e: Medium-Duty\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWire Shape\u003c\/strong\u003e: D-Shaped\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Chromium-Vanadium Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Blue\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.129 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ISO 10243, ISO 9001:2015, NAAMS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161905\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: DAYTON LAMINA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 9-1606-21\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DAYTON LAMINA","offers":[{"title":"Default Title","offer_id":51958123135282,"sku":"9-1606-21","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f723967a8d14df453171725d88071cbc.jpg?v=1789944898","url":"https:\/\/voomisupply.com\/products\/dayton-lamina-9-1606-21-die-spring-blue-medium-duty","provider":"Voomi Supply","version":"1.0","type":"link"}
