Associated Spring Raymond 204-724 Die Spring Blue

Product Description

The ASSOCIATED SPRING RAYMOND 204-724 is a heavy-duty die spring engineered for use in metal stamping, forming, and press tooling applications. Built from chromium alloy steel with a trapezoidal wire shape, it delivers consistent force and deflection performance under cyclic loading conditions. The spring features a 40 mm hole diameter, a 20 mm rod diameter, and a free length of 152 mm. With a spring rate of 294.64 N/mm and a maximum deflection load of 2941.20 N, this unit is well suited for high-load tooling setups where reliable spring return is critical. Installation and replacement are handled by tooling engineers, die setters, and maintenance technicians.

This die spring is used in stamping dies, injection molds, punching tools, and similar industrial tooling assemblies. The blue color designation indicates a medium-to-heavy load rating, which places it in a commonly specified range for progressive dies and compound dies in manufacturing environments. It rides on a guide rod and fits within a die pocket, providing consistent stripping, clamping, or return force during press cycles.

Key Features

• Trapezoidal wire shape for higher load capacity compared to round wire designs
• Chromium alloy steel construction for durability under repeated cycling
• 40 mm hole diameter accommodates standard guide rod sizing
• Maximum deflection of 57 mm with a travel-to-solid load of 2941.20 N
• Manufactured to ISO 10243 standards for interchangeable die spring dimensions
• Produced under ISO 9001:2008 and ISO/TS 16949:2009 certified quality systems

Compatibility

Designed as an ISO 10243-compliant die spring replacement suitable for stamping dies, forming tools, and press tooling assemblies requiring a 40 mm hole diameter, 20 mm rod diameter, and 152 mm free length in the blue load category.

Installation Notes

Die springs should be installed by qualified tooling or maintenance personnel with the press locked out and de-energized per applicable lockout/tagout procedures. Ensure the guide rod and die pocket dimensions match the spring bore and outer diameter before installation. Do not compress the spring beyond its rated maximum deflection, as exceeding travel-to-solid load will cause permanent set or failure. Inspect springs for fatigue cracking or length loss during scheduled die maintenance intervals.
