Associated Spring Raymond 104-648 Die Spring Red 12 in

Product Description

The ASSOCIATED SPRING RAYMOND 104-648 is a heavy-duty die spring designed for use in stamping dies, press tooling, and industrial machinery requiring consistent, repeatable compression force. Built from chromium alloy steel with a trapezoidal wire shape, it delivers a spring rate of 124.00 pounds per inch and a maximum deflection load of 550.6 pounds at full compression. The 12 inch free length and red color coding indicate a heavy load class, making this spring a direct fit for applications demanding high force output in a compact envelope. Installation is handled by toolmakers, die setters, and maintenance technicians working on industrial press equipment.

This die spring is suited for high-cycle stamping and forming applications in both production and maintenance environments. The red color designation follows internationally recognized die spring load classifications, identifying this unit as a heavy-load spring. Its 1-1/4 inch hole diameter and 5/8 inch rod diameter allow straightforward mounting on standard die posts or guide rods. Typical applications include blanking dies, forming dies, and component strippers in metal fabrication operations.

Key Features

• Trapezoidal wire cross-section provides higher load capacity relative to round-wire springs of the same envelope size
• Chromium alloy steel construction for high fatigue resistance and long service life in repetitive-cycle applications
• Red color code denotes heavy load class per standard die spring classification systems
• Spring rate of 124.00 pounds per inch for predictable, linear force output
• Maximum deflection of 4.44 inches with a maximum deflection load of 550.6 pounds
• Manufactured under ISO 9001:2008 and ISO/TS 16949:2009 certified quality systems with TUV Rheinland registration

Compatibility

Designed as a replacement or upgrade die spring for industrial stamping and forming dies using a 1-1/4 inch bore and 5/8 inch rod diameter with a 12 inch free length in the heavy (red) load class.

Installation Notes

Die springs should be installed by qualified toolmakers or die maintenance personnel familiar with press safety procedures. Always de-energize and lock out the press before servicing any die components. Inspect the mating die post or guide rod for wear or damage before installing a new spring, and ensure the rod diameter and bore clearances match the spring specifications. Do not compress this spring beyond its rated maximum deflection to avoid permanent set or failure.
