Associated Spring Raymond 104-708 Die Spring Red

Product Description

The ASSOCIATED SPRING RAYMOND 104-708 is a medium heavy-duty die spring rated for demanding press tooling and stamping applications. It features a 1-1/2 inch hole diameter, a 3/4 inch rod diameter, and a 2 inch free length. The trapezoidal wire cross-section provides a higher spring rate than round-wire designs of comparable size, delivering a spring rate of 1030 pounds per inch and a maximum deflection load of 799.2 pounds at 0.74 inches of maximum deflection. The red color coding identifies this spring as medium heavy-duty per international die spring standards. Manufactured from chromium alloy steel for durability under repeated cycle loads. This spring is installed by tool and die makers, press operators, and maintenance machinists working on punch press and stamping tooling.

The 104-708 is suited for use in punch and die sets, injection mold tooling, and other precision press applications where consistent spring force and cycle life are required. Its compact 2 inch free length makes it appropriate for applications with limited vertical space in the die set. The red duty rating designation aligns with ISO and international die spring classification systems, making it a recognized standard for medium heavy-duty replacement across production tooling environments.

Compatibility

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

Installation Notes

Die springs of this type are installed and replaced by tool and die makers or press maintenance technicians. Always de-energize and lock out the press before servicing the die set. Ensure the mating rod and hole dimensions in the die plate match the spring specifications before installation. Do not compress the spring beyond its rated maximum deflection of 0.74 inches, as over-compression will reduce cycle life and may cause spring failure.
