Associated Spring Raymond 103-732 Die Spring Blue

Product Description

The ASSOCIATED SPRING RAYMOND 103-732 is a heavy-duty die spring engineered for use in stamping dies, presses, and tooling fixtures where consistent force and reliable return travel are required. This spring features a 1-1/2 inch hole diameter, a 3/4 inch rod diameter, and an 8 inch free length. It delivers a maximum deflection load of 512 lb at a maximum deflection of 4 inches, producing a spring rate of 132 lb per inch. Wound from chromium alloy steel with a trapezoidal wire cross-section, the blue color coding indicates a medium-load duty rating consistent with standard die spring classifications. Installation and selection are handled by toolmakers, die maintenance technicians, and mechanical engineers.

This die spring is suited for industrial tooling applications including stamping presses, injection mold assemblies, and custom fixture builds in both production and job-shop environments. The blue designation identifies it as a medium-load spring, appropriate for applications requiring moderate force with controlled deflection. It fits standard die sets with a 1-1/2 inch bore and accommodates a 3/4 inch guide rod for lateral stability during compression cycles.

Key Features

• 1-1/2 inch hole diameter and 3/4 inch rod diameter for use with standard die set guide rods
• 8 inch free length with 4 inches of maximum deflection travel
• 512 lb maximum deflection load at full compression
• 132 lb per inch spring rate for consistent, predictable force output
• Trapezoidal wire profile for higher load capacity in a compact cross-section
• Chromium alloy steel construction for durability under repeated cycling
• Manufactured under ISO 9001:2008 and ISO/TS 16949:2009 certified quality systems

Compatibility

Designed as a direct-fit die spring for standard tooling applications using a 1-1/2 inch bore and 3/4 inch guide rod. Consult your tooling drawings to confirm free length and load requirements before substituting for an existing spring.

Installation Notes

Die spring replacement and tooling maintenance should be performed by qualified toolmakers or die technicians with the press fully de-energized and locked out per OSHA lockout/tagout procedures. Inspect the guide rod for wear or scoring before installing the new spring, as surface damage can accelerate spring fatigue. Never compress a die spring beyond its rated maximum deflection of 4 inches, as over-compression causes permanent set and early failure. Preload and travel should be verified against the tooling design specification before returning the die to production.
