Associated Spring Raymond 104-204 Die Spring Red

Product Description

The ASSOCIATED SPRING RAYMOND 104-204 is a medium heavy-duty die spring designed for use in stamping dies, punch presses, and industrial tooling applications. Built from chromium alloy steel with a trapezoidal wire cross-section, it delivers a spring rate of 155 pounds per inch and handles a maximum deflection load of 62.2 pounds over a maximum deflection of 0.37 inches. The color-coded red finish identifies its medium heavy-duty duty rating at a glance, simplifying spring selection and replacement in high-volume tooling environments. It ships individually and is suited for installation by toolmakers, die setters, and maintenance machinists.

This die spring is intended for use in press tooling, injection mold assemblies, and mechanical fixtures requiring consistent, repeatable force. Its 0.5-inch hole diameter and 9/32-inch rod diameter allow it to seat over a guide rod or inside a drilled pocket in standard die set configurations. The 1-inch free length makes it appropriate for compact die spaces where stroke length is limited. Compliance with ISO 9001:2008 and ISO/TS 16949:2009 standards supports use in quality-controlled manufacturing environments.

Key Features

• Chromium alloy steel construction for high fatigue resistance in cyclic loading
• Trapezoidal wire shape increases load capacity relative to round-wire springs of the same envelope
• Medium heavy-duty rating with 62.2-pound maximum deflection load
• Spring rate of 155 pounds per inch for predictable, consistent force output
• Color-coded red body for fast visual identification of duty class
• Manufactured under ISO 9001:2008 and ISO/TS 16949:2009 certified quality systems

Compatibility

Designed as an OEM-style replacement or direct-fit die spring for press tooling and mechanical assemblies requiring a 0.5-inch hole diameter, 9/32-inch rod diameter, and 1-inch free length in a medium heavy-duty application.

Installation Notes

Die springs should be installed by qualified toolmakers or maintenance personnel familiar with press die assembly. Always de-energize and lock out the press before accessing die sets. Ensure the guide rod diameter does not exceed 9/32 inches and the spring pocket diameter is sized to the 0.5-inch outer hole dimension to prevent spring buckling or misalignment. Never compress the spring beyond its rated maximum deflection of 0.37 inches, as overcompression will permanently damage the spring and may cause premature failure.
