Built from chromium alloy steel with a trapezoidal wire cross-section, it delivers a spring rate of 750 pounds per inch and a maximum deflection load of 328.1 pounds at 0.44 inches of travel. The green color coding identifies it as an extra heavy-duty grade per standard die spring classifications. This spring suits tooling applications where precise load control and long fatigue life are required under repeated compression cycles.\u003c\/p\u003e\n\u003cp\u003eThis die spring is used in metal stamping, forming, and injection mold tooling across manufacturing and fabrication environments. It fits rod diameters up to 0.375 inches and seats inside a 0.75-inch bore. Typical installations include stripper plates, lifters, and pressure pads in progressive dies and single-station tooling. It is appropriate for both light production shops and high-volume automated press lines where reliable spring return force is critical to part quality and die longevity.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eExtra heavy-duty duty rating with 328.1 lb maximum deflection load\u003c\/li\u003e\n  \u003cli\u003e750 pounds per inch spring rate for consistent, predictable force output\u003c\/li\u003e\n  \u003cli\u003eTrapezoidal wire cross-section maximizes coil density and fatigue life\u003c\/li\u003e\n  \u003cli\u003eChromium alloy steel construction resists wear and deformation under high-cycle use\u003c\/li\u003e\n  \u003cli\u003eGreen color coding provides quick visual identification of duty rating at the press\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 requiring a 0.75-inch hole diameter, 0.375-inch rod diameter, and 1.75-inch free length in an extra heavy-duty green-grade application.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eDie springs are installed and serviced by tool and die makers or press maintenance technicians. Always de-energize and lock out the press before accessing the die set. Ensure the spring seats fully and squarely in the pocket without side-loading the rod. Do not compress beyond the rated maximum deflection of 0.44 inches, as over-compression accelerates fatigue failure and can cause catastrophic spring breakage inside the die.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRod Diameter\u003c\/strong\u003e: 0.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFree Length\u003c\/strong\u003e: 1.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Deflection Load\u003c\/strong\u003e: 328.1 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Deflection\u003c\/strong\u003e: 0.44 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpring Rate\u003c\/strong\u003e: 750 pounds per inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDuty Rating\u003c\/strong\u003e: Extra Heavy-Duty\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor Code\u003c\/strong\u003e: Green\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\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANAB Accredited; ISO 9001:2008 Certified; ISO\/TS 16949:2009 Certified; TUV Rheinland Registered\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: 106-407\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ASSOCIATED SPRING","offers":[{"title":"Default Title","offer_id":51995387658546,"sku":"106-407","price":18.37,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/48613bbae3935ed609d6aa47db766c1c.jpg?v=1789992638","url":"https:\/\/voomisupply.com\/products\/associated-spring-raymond-106-407-die-spring-extra-heavy-duty","provider":"Voomi Supply","version":"1.0","type":"link"}
