Associated Spring Raymond 204-936 Die Spring 9in Blue

Product Description

The ASSOCIATED SPRING RAYMOND 204-936 is a medium-duty die spring engineered for use in metal stamping dies, press tooling, and industrial fixture applications. Built from chromium alloy steel, it delivers consistent return force and long fatigue life under cyclic compression loads. Key specs include a 9-inch (229 mm) free length, a 2.480-inch (63 mm) hole diameter, and a 1.496-inch (38 mm) rod diameter. The trapezoidal wire cross-section increases load capacity relative to round-wire designs of the same envelope size. The blue color designation indicates medium-duty load class per ISO 10243. Toolmakers, die setters, and maintenance technicians are the typical installers of this component.

This die spring is suited for metal stamping presses, injection mold tooling, and general industrial machinery where a controlled, repeatable spring return is required. With a maximum deflection of 3.386 inches (86 mm) and a maximum deflection load of 1,724.55 pounds (7,671.20 N), it handles moderate to heavy cyclic loads in standard die sets. Applications span both light manufacturing and heavy industrial press environments. It is typically installed in the die plate bore, guided by a rod or seated in a counterbored hole, and selected when consistent stripping or return force is needed across high-cycle tooling.

Key Features

• Medium-duty load class, color-coded blue per ISO 10243 for straightforward identification and replacement
• Trapezoidal wire profile provides higher load density compared to conventional round-wire die springs
• Chromium alloy steel construction for fatigue resistance and durability under repeated compression cycles
• 9-inch (229 mm) free length accommodates deep die sets and extended stroke applications
• Maximum deflection of 3.386 inches (86 mm) at a load of 1,724.55 pounds (7,671.20 N)
• Conforms to ISO 10243 dimensional and load standards

Compatibility

Designed as an OEM-style replacement or new installation die spring for medium-duty press tooling and stamping die sets requiring a 63 mm hole diameter and 38 mm rod diameter per ISO 10243 specifications.

Installation Notes

Die springs of this type are installed by toolmakers or die maintenance technicians with the press locked out and all stored energy fully dissipated before service begins. The spring should be guided by a rod seated through the inner diameter or a counterbored pocket on the outer diameter to prevent buckling under load. Never exceed the rated maximum deflection, as compressing a die spring to solid will rapidly degrade fatigue life. Verify the bore and rod diameters in the die set match the spring dimensions before installation.
