Associated Spring Raymond 103-412 Die Spring Blue Medium-duty

Product Description

The ASSOCIATED SPRING RAYMOND 103-412 is a medium-duty die spring designed for use in stamping dies, punch presses, and other tooling applications where consistent, controlled compression force is required. Built from chromium alloy steel with a trapezoidal wire cross-section, it delivers a spring rate of 101 pounds per inch and a maximum deflection load of 144 pounds at full compression. The 3-inch free length, 3/4-inch hole diameter, and 3/8-inch rod diameter make it a direct fit for standard die sets requiring a blue-coded medium-duty spring. This part is typically installed by toolmakers, die setters, and maintenance machinists.

This die spring is suited for industrial tooling environments including metal stamping, forming, and injection mold applications. The blue color coding follows ISO 10243 duty-rating conventions, identifying this spring as a medium-duty unit. It is appropriate for applications demanding up to 1.5 inches of maximum deflection and a sustained load capacity of 144 pounds, making it a practical choice for moderate-force compression tooling setups in both production and maintenance-repair contexts.

Key Features

• Chromium alloy steel construction for durability under repeated compression cycles
• Trapezoidal wire cross-section provides higher load capacity relative to round wire at equivalent size
• 101 lb/inch spring rate with 144-pound maximum deflection load
• 1.5-inch maximum deflection at full compression
• Blue color coding indicates medium-duty rating per ISO 10243 convention
• Manufactured under ISO 9001:2008 and ISO/TS 16949:2009 certified quality systems; TUV Rheinland registered

Compatibility

Designed as an OEM-style replacement or standard die spring for tooling applications requiring a 3/4-inch hole diameter, 3/8-inch rod diameter, and 3-inch free length in a medium-duty blue-coded spring specification.

Installation Notes

Die spring installation and replacement should be performed by qualified toolmakers or die maintenance personnel with the press fully de-energized, locked out, and tagged out per OSHA lockout/tagout requirements. Inspect the mating die pocket and guide rod for wear or damage before seating the new spring. Do not compress the spring beyond its rated maximum deflection of 1.5 inches, as over-compression will reduce service life and may cause premature failure.
