Associated Spring Raymond 204-518 Die Spring Medium Duty Blue

Product Description

The ASSOCIATED SPRING RAYMOND 204-518 is a medium-duty die spring designed for use in stamping dies, injection molds, and other precision tooling applications where consistent, repeatable spring force is required. Built from chromium alloy steel with a trapezoidal wire shape, this spring delivers a maximum deflection load of 270.67 pounds (1204 N) over a maximum deflection of 43.00 mm. The blue color coding follows ISO 10243 standards, immediately identifying it as a medium-duty rating for quick selection during tooling setup or maintenance. Machinists, tool and die makers, and industrial maintenance technicians install this part.

This die spring is suited for press tooling, die sets, and automated manufacturing equipment requiring reliable cyclic compression performance. The 25.00 mm hole diameter and 12.50 mm rod diameter allow straightforward drop-in fitment on standard ISO-spec die components. With a free length of 4.5 inches (115.00 mm) and a travel-to-solid load measurement of 43.00 mm, this spring fits a wide range of standard tooling configurations in both light industrial and production-level shop environments.

Key Features

• Medium-duty rating with maximum deflection load of 270.67 pounds (1204 N)
• Blue color coding per ISO 10243 for fast, reliable duty identification
• Trapezoidal wire shape provides higher load capacity versus round wire at equivalent outside diameter
• Chromium alloy steel construction for fatigue resistance in cyclic compression applications
• 4.5 inch (115.00 mm) free length with 43.00 mm maximum deflection travel
• 25.00 mm hole diameter and 12.50 mm rod diameter for standard ISO tooling fitment

Compatibility

Designed as an ISO 10243-compliant medium-duty die spring for use in standard stamping dies, mold bases, and press tooling that accept a 25.00 mm hole diameter and 12.50 mm rod diameter.

Installation Notes

Installation is typically performed by tool and die makers or industrial maintenance technicians during die assembly or rebuild. Before replacing a die spring, de-energize and lock out the press or molding machine per applicable safety procedures. Inspect the mating hole and rod surfaces for wear or damage before seating the new spring. Do not compress the spring beyond its rated maximum deflection to avoid premature failure or set.
