Dayton Lamina 9-2424-11 Die Spring Light-duty Green

Product Description

The DAYTON LAMINA 9-2424-11 is a light-duty die spring designed for use in stamping dies, press tooling, and precision metal forming applications. Built from chromium-vanadium steel, it features a 1-1/2 inch hole diameter, a 3/4 inch rod diameter, and a 6 inch free length. The wire cross-section is D-shaped, which increases the active coil surface and improves load consistency over the spring's service life. At maximum deflection of 2.39 inches, the spring delivers a load of 421 pounds. Maximum operating deflection is rated at 40 percent of free length. This spring is color-coded green per standard die spring classification for light-duty applications and weighs 0.912 pounds.

This spring is suited for light-duty tooling setups in stamping presses, injection molds, and die assemblies where consistent return force and dimensional accuracy are required. It fits over a 3/4 inch guide rod and seats in a 1-1/2 inch pocket. Toolmakers, die setters, and precision machining shops are the primary installers. The 6 inch free length makes it appropriate for applications requiring moderate travel with controlled preload.

Key Features

• Light-duty classification, color-coded green for easy identification during die setup
• D-shaped wire profile for improved load distribution and longer fatigue life
• 421 pounds maximum deflection load at 2.39 inches of travel
• 40 percent maximum operating deflection rating
• Chromium-vanadium steel construction for strength and durability under cyclic loading
• Meets ISO 10243 International Standard, ISO 9001:2015, and NAAMS requirements

Compatibility

Designed as a standard die spring replacement or new installation for light-duty press tooling and stamping die assemblies requiring a 1-1/2 inch hole diameter, 3/4 inch rod diameter, and 6 inch free length per ISO 10243 dimensional standards.

Installation Notes

Installation is typically performed by toolmakers or die setters during die build or maintenance. Ensure the guide rod and spring pocket diameters match the spring specifications before installation to prevent binding or misalignment. Never compress the spring beyond the rated maximum operating deflection, as over-compression can cause permanent set or premature failure. Inspect springs regularly for signs of fatigue, corrosion, or uneven coil contact during scheduled die maintenance.
