Associated Spring Raymond 204-105 Die Spring 1-1/4 in Blue

Product Description

The ASSOCIATED SPRING RAYMOND 204-105 is a heavy-duty die spring designed for use in stamping dies, punch presses, and precision tooling applications. Built from chromium alloy steel with a trapezoidal wire cross-section, it delivers higher load capacity and longer service life compared to standard round-wire springs. The blue color coding indicates its load classification, allowing quick identification during die setup and maintenance. With a free length of 1-1/4 inches (32 mm) and a rod diameter of 5 mm, this spring is sized for compact die cavities where precise, repeatable force is required.

This die spring is suited for metal stamping, forming, and progressive die tooling in manufacturing environments. It fits applications where consistent spring force and deflection control are critical to part quality and die longevity. Tool and die makers, maintenance technicians, and industrial machine shops will find it appropriate for both new die builds and replacement service on existing tooling assemblies.

Key Features

• Trapezoidal wire shape provides higher load density versus round-wire die springs
• Chromium alloy steel construction for durability under cyclic compressive loads
• Blue color coding identifies load class for fast visual sorting during die maintenance
• 1-1/4 inch (32 mm) free length suits compact die pockets
• 5 mm rod diameter for precise guided installation on standard die pins
• Manufactured to ISO 10243 die spring standards

Compatibility

Designed as an ISO 10243-compliant replacement or new-build die spring for use in standard die sets accepting a 5 mm guide rod and a 10 mm hole diameter.

Installation Notes

Die springs are installed and serviced by tool and die makers or maintenance technicians working on stamping and forming tooling. Always de-energize and lock out the press before disassembling any die set. Ensure the guide rod and hole diameters match the spring specifications before installation to prevent side loading. Never compress a die spring beyond its rated maximum deflection, as over-compression accelerates fatigue failure.
