Built from chromium alloy steel with a trapezoidal wire cross-section, this spring delivers reliable, consistent force under repeated compression cycles. It has a free length of approximately 2 inches (51 mm), a rod diameter of 10 mm, and a hole diameter of 20 mm. The blue color coding identifies it as a medium-duty rating per ISO 10243. Toolmakers, die setters, and maintenance technicians working with metal-forming equipment are the typical installers.\u003c\/p\u003e\n\u003cp\u003eThis die spring is suited for use in stamping dies, injection mold assemblies, stripping applications, and general industrial press tooling where controlled return force is required. Its trapezoidal wire profile maximizes load capacity within a compact envelope, making it a practical choice when space inside a die set is limited. The ISO 10243 designation ensures dimensional and load interchangeability with other compliant springs of the same class and color code.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eChromium alloy steel construction for high fatigue resistance under cyclic loading\u003c\/li\u003e\n  \u003cli\u003eTrapezoidal wire cross-section increases load capacity compared to round-wire springs of similar size\u003c\/li\u003e\n  \u003cli\u003eBlue color code denotes medium-duty rating per ISO 10243\u003c\/li\u003e\n  \u003cli\u003eMaximum deflection load of 178.12 pounds (792.30 N) at full 19 mm travel to solid\u003c\/li\u003e\n  \u003cli\u003eRod diameter of 10 mm and hole diameter of 20 mm for standard die-set fitment\u003c\/li\u003e\n  \u003cli\u003eISO 10243 compliant, ensuring interchangeability with other conforming medium-duty die springs\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an ISO 10243 medium-duty die spring replacement suitable for standard punch-and-die tooling applications requiring a 20 mm hole diameter, 10 mm rod diameter, and 51 mm free length.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eDie springs are installed and replaced by toolmakers or maintenance technicians during die service or rebuild. Always de-energize and lock out the press before accessing the die set. Inspect the rod and bore for wear or misalignment before installation, as side loading will shorten spring service life. Do not compress the spring beyond its rated maximum deflection of 19 mm.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFree Length\u003c\/strong\u003e: 2 inches (51 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRod Diameter\u003c\/strong\u003e: 10 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 20 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Deflection\u003c\/strong\u003e: 19 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Deflection Load\u003c\/strong\u003e: 178.12 pounds (792.30 N)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDuty Rating\u003c\/strong\u003e: Medium-Duty\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor Code\u003c\/strong\u003e: Blue\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWire Shape\u003c\/strong\u003e: Trapezoidal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Chromium Alloy Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Number\u003c\/strong\u003e: 10243\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161905\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: ASSOCIATED SPRING RAYMOND\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 204-408\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ASSOCIATED SPRING","offers":[{"title":"Default Title","offer_id":51985257103666,"sku":"204-408","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/01994403ee36035e0eac2097b386e3ec.jpg?v=1789985318","url":"https:\/\/voomisupply.com\/products\/associated-spring-raymond-204-408-die-spring-medium-duty","provider":"Voomi Supply","version":"1.0","type":"link"}
