Associated Spring Raymond 204-506 Die Spring 1.5 in

Product Description

The ASSOCIATED SPRING RAYMOND 204-506 is a medium-duty die spring engineered for use in stamping dies, injection molds, and similar tooling applications. Built from chromium alloy steel with a trapezoidal wire cross-section, it delivers consistent load characteristics and resists fatigue across high-cycle operations. The spring has a free length of 1.5 inches (38 mm) and a maximum deflection of 0.551 inches (14 mm), reaching a maximum deflection load of 292.7 pounds (1302 N). The blue color coding identifies the medium-duty load class per ISO 10243. Tool and die makers, mold technicians, and maintenance machinists are the primary installers of this component.

This die spring is suited for medium-duty tooling environments where reliable, repeatable spring force is required within a compact envelope. It fits applications calling for a hole diameter of approximately 0.984 inches (25 mm) and a rod diameter of approximately 0.492 inches (12.5 mm). Typical use cases include progressive dies, blanking dies, stripper plates, and injection mold lifter assemblies in both production shop and maintenance settings.

Key Features

• Blue color code identifies medium-duty load rating per ISO 10243
• Trapezoidal wire cross-section provides higher load density than round-wire springs of comparable size
• Chromium alloy steel construction for fatigue resistance in high-cycle tooling applications
• Free length of 1.5 inches (38 mm) with 0.551 inches (14 mm) maximum deflection to solid
• Maximum deflection load of 292.7 pounds (1302 N)
• Conforms to ISO 10243 die spring standards

Compatibility

Designed as an ISO 10243 medium-duty die spring compatible with tooling bores sized for a 25 mm hole diameter and a 12.5 mm rod diameter. Confirm free length and load requirements against your die or mold design specifications before installation.

Installation Notes

Die spring installation is typically performed by tool and die makers or maintenance machinists during die build or repair. Always de-energize and lock out the press or machine before servicing any tooling components. Verify that the spring seating pocket and guide rod dimensions match the specified hole and rod diameters to prevent buckling or premature wear. Do not compress the spring beyond its rated maximum deflection to solid, as over-compression will permanently reduce load capacity and service life.
