It features a trapezoidal wire cross-section, which increases contact area and load capacity compared to round-wire springs of the same envelope size. With a free length of 1.25 inches (32 mm), a rod diameter of 10 mm, and a hole diameter of 20 mm, this spring is sized for medium-duty tooling setups. It delivers a spring rate of 256.96 N\/mm and a maximum deflection load of 562.50 N at full travel. The chromium alloy steel construction provides durability under repeated cycling in die and press environments. Installation is performed by toolmakers and die maintenance technicians.\u003c\/p\u003e\n\u003cp\u003eThis die spring is suited for use in stamping and forming dies in both production and toolroom settings. The green color coding identifies it within the ISO 10243 heavy-load classification range, helping toolmakers quickly identify and replace springs during die maintenance. Typical applications include stripper plates, lifters, and pressure pads in progressive, compound, and transfer dies. The 20 mm hole diameter and 10 mm rod diameter make it compatible with standard die set configurations using metric rod and bore sizing.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eTrapezoidal wire shape increases load-bearing surface area for higher fatigue life versus round-wire alternatives\u003c\/li\u003e\n  \u003cli\u003eGreen color code indicates heavy-load rating per ISO 10243 classification\u003c\/li\u003e\n  \u003cli\u003eChromium alloy steel construction for durability under high-cycle press conditions\u003c\/li\u003e\n  \u003cli\u003eMaximum deflection of 12.50 mm with a travel-to-solid load matching maximum deflection\u003c\/li\u003e\n  \u003cli\u003eManufactured under ISO 9001:2008 and ISO\/TS 16949:2009 certified quality systems with TUV Rheinland registration\u003c\/li\u003e\n  \u003cli\u003eANAB accredited production for consistent dimensional and load performance\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-install die spring for industrial stamping dies and press tooling requiring a 20 mm hole diameter, 10 mm rod diameter, and 32 mm free length per ISO 10243 specifications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eDie springs should be installed by qualified toolmakers or die maintenance personnel with the press fully de-energized and locked out per OSHA lockout\/tagout procedures. Ensure the mating bore and rod diameters match the spring specifications before installation to prevent buckling or premature failure. Do not compress the spring beyond its rated maximum deflection of 12.50 mm. Inspect seating surfaces for burrs or damage that could cause uneven loading or accelerated wear.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFree Length\u003c\/strong\u003e: 1.25 inches (32 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 20 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRod Diameter\u003c\/strong\u003e: 10 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWire Shape\u003c\/strong\u003e: Trapezoidal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor Code\u003c\/strong\u003e: Green\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpring Rate\u003c\/strong\u003e: 256.96 N\/mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Deflection\u003c\/strong\u003e: 12.50 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Deflection Load\u003c\/strong\u003e: 562.50 N\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTravel To Solid Load\u003c\/strong\u003e: 12.50 mm\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\u003eCertifications\u003c\/strong\u003e: ANAB Accredited, ISO 9001:2008, ISO\/TS 16949:2009, TUV Rheinland Registered\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: 203-405\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ASSOCIATED SPRING","offers":[{"title":"Default Title","offer_id":52041533096242,"sku":"203-405","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1cbe4612a009eb5f2dca5c27211f7e09_7f915450-7597-4c1e-a732-27b3b29864f9.jpg?v=1790027784","url":"https:\/\/voomisupply.com\/products\/associated-spring-raymond-203-405-die-spring-1-1-4-in","provider":"Voomi Supply","version":"1.0","type":"link"}
