Associated Spring Raymond 104-312 Die Spring Red

Product Description

The ASSOCIATED SPRING RAYMOND 104-312 is a heavy-duty die spring engineered for use in stamping, punching, and forming tooling applications. It features a trapezoidal wire cross-section that delivers higher load capacity compared to round-wire springs of the same envelope size. With a free length of 3 inches, a hole diameter of 0.625 inches, and a rod diameter of 0.34375 inches, this spring is rated for a maximum deflection load of 111 pounds at 1.11 inches of maximum deflection. The spring rate is 100 pounds per inch. Constructed from chromium alloy steel, the red color coding identifies it within the standard heavy-load classification used across the die spring industry.

This spring is designed for installation in die sets and press tooling where consistent, repeatable force is required over high cycle counts. It is suited for use in metal stamping dies, injection mold assemblies, and other precision tooling fixtures. Licensed tool-and-die makers and tooling technicians are the typical installers. The red color band places this part in the heavy-load range, making it appropriate for applications requiring firm return force within a compact axial space.

Key Features

• Trapezoidal wire shape provides higher load density than equivalent round-wire die springs
• 111-pound maximum deflection load at 1.11 inches maximum deflection
• 100 pounds per inch spring rate for predictable, linear force output
• Chromium alloy steel construction for fatigue resistance under repetitive cycling
• Red color coding indicates heavy-load classification per die spring industry standards
• Manufactured under ISO 9001:2008 and ISO/TS 16949:2009 certified quality systems

Compatibility

Designed as an OEM-style replacement or new-build component for die sets and press tooling requiring a 0.625-inch hole diameter, 0.34375-inch rod diameter, and 3-inch free length heavy-load die spring.

Installation Notes

Installation is performed by qualified tooling technicians or tool-and-die makers during die build or maintenance. Ensure the mating rod and pocket dimensions match the specified rod diameter of 0.34375 inches and hole diameter of 0.625 inches before installation. Do not compress the spring beyond its rated maximum deflection of 1.11 inches, as over-compression will reduce fatigue life. Inspect the spring seating surfaces for burrs or damage that could cause uneven loading.
