Dayton Lamina 9-2416-11 Die Spring 4 Inches Light-duty Green

Product Description

The DAYTON LAMINA 9-2416-11 is a light-duty die spring designed for use in stamping dies, molds, and precision tooling applications. Built from chromium-vanadium steel with a D-shaped wire profile, it provides consistent, reliable force return in high-cycle press operations. The spring has a 1-1/2 inch hole diameter, a 3/4 inch rod diameter, and a 4 inch free length. It delivers a maximum deflection load of 439 pounds at a maximum deflection of 1.61 inches, with a maximum operating deflection of 40 percent of free length. The green color designation identifies this as a light-duty rated unit per ISO 10243 standards. Licensed toolmakers and die maintenance technicians are the typical installers.

This die spring is suited for light-duty tooling applications in stamping, forming, and injection mold assemblies where controlled spring force and precise travel are required. It fits standard die sets accepting a 1-1/2 inch hole bore and a 3/4 inch guide rod. The 4 inch free length accommodates tooling designs requiring moderate working height. It is applicable in both production stamping environments and prototype tooling setups across automotive, fabrication, and general manufacturing industries.

Key Features

• Chromium-vanadium steel construction for high fatigue resistance in repetitive-cycle applications
• D-shaped wire profile provides stable seating and reduces rotation during compression
• Maximum deflection load of 439 pounds at 1.61 inches deflection
• Maximum operating deflection rated at 40 percent of free length
• Travel to solid load of 2.01 inches
• Green color coding per ISO 10243 light-duty classification for quick visual identification

Compatibility

Designed as an ISO 10243 compliant replacement or new-installation die spring for standard light-duty tooling applications accepting a 1-1/2 inch hole diameter and a 3/4 inch guide rod diameter.

Installation Notes

Die spring installation and replacement should be performed by qualified toolmakers or die maintenance technicians with the press locked out and all stored energy released before service. Inspect the mating guide rod and bore for wear or damage before installing a new spring. Do not exceed the maximum operating deflection of 40 percent during normal production cycles, as over-compression accelerates fatigue failure. Ensure the spring seats squarely in the die pocket to prevent side loading.
