Built from chromium alloy steel with a trapezoidal wire cross-section, this spring delivers consistent force and extended cycle life compared to standard round-wire springs. It carries a free length of 1-1\/4 inches (32 mm), a rod diameter of 12.50 mm, and a hole diameter of 25.00 mm. The green color code identifies it within the ISO 10243 classification system, indicating its load range. Toolmakers, die setters, and maintenance technicians are the primary installers of this component.\u003c\/p\u003e\n\u003cp\u003eThis die spring is suited for light-to-medium load tooling setups in both production stamping operations and custom fabrication environments. It is designed to fit standard die sets where a 25 mm hole diameter and 12.50 mm rod diameter are specified. The trapezoidal wire profile increases the active material cross-section, allowing greater energy storage within the same envelope compared to conventional round-wire springs. It is appropriate for applications requiring repeatable deflection performance under cyclic loading conditions.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eChromium alloy steel construction for high fatigue resistance and durability in cyclic tooling applications\u003c\/li\u003e\n  \u003cli\u003eTrapezoidal wire cross-section maximizes energy storage within the standard die spring envelope\u003c\/li\u003e\n  \u003cli\u003eGreen color code per ISO 10243 standard for straightforward load-range identification and replacement sourcing\u003c\/li\u003e\n  \u003cli\u003eMaximum deflection of 12.50 mm with a spring rate of 458.53 N\/mm for predictable, repeatable force output\u003c\/li\u003e\n  \u003cli\u003eMaximum deflection load of 1003.80 N supports consistent clamping and stripping force in stamping dies\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\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-fit die spring for tooling applications specifying a 25 mm hole diameter, 12.50 mm rod diameter, and 32 mm free length in accordance with ISO 10243 green-series standards.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eDie spring installation and replacement should be performed by qualified toolmakers or die maintenance technicians with the press powered down and all stored energy fully released before disassembly. Inspect the mating rod and hole bores for wear or out-of-round conditions before seating the new spring, as oversized or undersized fits accelerate fatigue failure. Never use a spring that shows visible cracking, coil set, or a free length shorter than specification. Consult applicable workplace safety standards and machinery safety codes during press die service.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFree Length\u003c\/strong\u003e: 1-1\/4 inches (32 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 25 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRod Diameter\u003c\/strong\u003e: 12.50 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\u003eTravel To Solid Load\u003c\/strong\u003e: 12.50 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Deflection Load\u003c\/strong\u003e: 1003.80 N\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpring Rate\u003c\/strong\u003e: 458.53 N\/mm\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\u003eColor Code\u003c\/strong\u003e: Green\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 Certified; ISO\/TS 16949:2009 Certified; 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: 203-505\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ASSOCIATED SPRING","offers":[{"title":"Default Title","offer_id":52113639637298,"sku":"203-505","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b6c5907c93a02e6cd962c76155b71015.jpg?v=1790078488","url":"https:\/\/voomisupply.com\/products\/associated-spring-raymond-203-505-die-spring-1-1-4-in","provider":"Voomi Supply","version":"1.0","type":"link"}
