Built from chromium alloy steel with a trapezoidal wire cross-section, this spring delivers a spring rate of 380 pounds per inch and a maximum deflection load of 175.8 pounds over a maximum deflection of 0.46 inches. The red color coding identifies the medium heavy-duty duty rating per industry-standard die spring classifications. Licensed HVAC, tooling, and industrial maintenance professionals install this type of spring during die set assembly or scheduled die maintenance.\u003c\/p\u003e\u003cp\u003eThis die spring is suited for use in metal stamping dies, injection mold tooling, and industrial press applications where controlled, repeatable spring force is required. The 0.75-inch hole diameter accommodates standard die set guide posts, and the 0.375-inch rod diameter provides clearance for standard guide rods. The 1.25-inch free length makes it appropriate for compact die sets with limited spring pocket depth. It is commonly installed in both OEM die builds and die repair or replacement scenarios in manufacturing environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eTrapezoidal wire cross-section delivers higher load capacity per inch of deflection compared to round wire designs\u003c\/li\u003e\n\u003cli\u003eMedium heavy-duty rating with a spring rate of 380 pounds per inch\u003c\/li\u003e\n\u003cli\u003eMaximum deflection load of 175.8 pounds at 0.46 inches of travel\u003c\/li\u003e\n\u003cli\u003eChromium alloy steel construction for durability under cyclic loading\u003c\/li\u003e\n\u003cli\u003eRed color coding for fast duty-rating identification during die assembly\u003c\/li\u003e\n\u003cli\u003eManufactured under ISO 9001:2008 and ISO\/TS 16949:2009 certified quality systems\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard-dimension replacement die spring for medium heavy-duty applications requiring a 0.75-inch hole diameter, 0.375-inch rod diameter, and 1.25-inch free length in stamping dies and industrial tooling.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by tooling technicians or die maintenance personnel during die set assembly or repair. Always relieve all press pressure and lock out the press before removing or replacing die springs. Inspect the spring pocket and guide rod for wear or damage before seating the new spring. Do not compress the spring beyond its rated maximum deflection during setup or operation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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: 1.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Deflection Load\u003c\/strong\u003e: 175.8 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Deflection\u003c\/strong\u003e: 0.46 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpring Rate\u003c\/strong\u003e: 380 pounds per inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDuty Rating\u003c\/strong\u003e: Medium Heavy-Duty\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Red\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: 0.06 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\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 104-405\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ASSOCIATED SPRING","offers":[{"title":"Default Title","offer_id":52120684855602,"sku":"104-405","price":15.72,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ae72408499618285832852d57fc98f1b.jpg?v=1790083959","url":"https:\/\/voomisupply.com\/products\/associated-spring-raymond-104-405-die-spring-red-medium-heavy-duty","provider":"Voomi Supply","version":"1.0","type":"link"}
