Associated Spring Raymond 104-710 Die Spring Red Medium Heavy-duty

Product Description

The ASSOCIATED SPRING RAYMOND 104-710 is a medium heavy-duty die spring engineered for use in stamping dies, punch presses, and industrial tooling applications. It features a 1-1/2 inch hole diameter, a 3/4 inch rod diameter, and a free length of 2-1/2 inches. The trapezoidal wire cross-section maximizes the amount of material in the coil, which increases load capacity and service life compared to standard round-wire springs. Constructed from chromium alloy steel, this spring delivers consistent force output under high-cycle conditions. It is color-coded red to indicate its medium heavy-duty load rating, following the ISO die spring color standard for quick identification during tooling setup and maintenance.

This die spring is suited for use in metal stamping and forming dies, injection mold strippers, and mechanical press tooling where controlled, repeatable spring force is required. Toolmakers, die setters, and maintenance technicians working in stamping and fabrication shops are the primary installers. The red color coding makes it straightforward to identify and replace like-for-like during die maintenance. Its compact 2-1/2 inch free length fits standard die set configurations where vertical space is limited.

Key Features

• Trapezoidal wire profile increases load capacity and fatigue life versus round-wire alternatives
• Maximum deflection load of 791.8 pounds at 0.93 inches of compression
• Spring rate of 812 pounds per inch for predictable, linear force output
• Red color coding indicates medium heavy-duty duty rating per ISO die spring standards
• Chromium alloy steel construction resists fatigue under high-cycle press operation
• Manufactured under ISO 9001:2008 and ISO/TS 16949:2009 certified quality systems

Compatibility

Designed as a standard-format die spring for use in stamping dies, punch press tooling, and mold assemblies requiring a 1-1/2 inch hole diameter and 3/4 inch guide rod with a 2-1/2 inch free length and medium heavy-duty load rating.

Installation Notes

Die springs should be installed by qualified toolmakers or die maintenance technicians familiar with press tooling safety procedures. Always de-energize and lock out the press before removing or installing die components. Ensure the guide rod diameter and pocket bore match the spring specifications before installation to prevent buckling or misalignment. Do not compress the spring beyond its rated maximum deflection of 0.93 inches, as over-compression will reduce fatigue life and can cause premature failure.
