Dayton Lamina 9-1620-36 Die Spring Yellow Extra Heavy-duty

Product Description

The DAYTON LAMINA 9-1620-36 is an extra heavy-duty die spring designed for use in stamping dies, molds, and precision tooling applications. It features a 1 inch hole diameter, a 1/2 inch rod diameter, and a 5 inch free length. Manufactured from chromium-vanadium steel, this spring delivers a maximum deflection load of 515 pounds and a maximum deflection of 1.25 inches, making it well suited for high-cycle, high-load tooling environments. The D-shaped wire profile provides consistent force distribution and improved stability under compression. Licensed toolmakers and die maintenance technicians are the primary installers of this component.

This die spring is intended for use in metal stamping dies, injection molds, and progressive die assemblies where reliable, repeatable spring force is required. It is color-coded yellow in accordance with ISO 10243 standards, identifying its extra heavy-duty load class. Typical installations include stripper plates, lifters, and cam-return mechanisms in both prototype and production tooling. The 25 percent maximum operating deflection rating supports controlled travel within the designed range of the tooling assembly.

Key Features

• Extra heavy-duty load rating with a maximum deflection load of 515 pounds
• Chromium-vanadium steel construction for high-cycle fatigue resistance
• D-shaped wire profile for consistent seating and lateral stability
• Yellow color coding per ISO 10243 for easy load-class identification in the field
• Maximum deflection of 1.25 inches with a travel to solid load of 1.64 inches
• Meets ISO 10243, ISO 9001:2015, and NAAMS standards

Compatibility

Designed as a standard ISO 10243 extra heavy-duty die spring for use in stamping dies, molds, and precision tooling assemblies requiring a 1 inch hole diameter, 1/2 inch rod diameter, and 5 inch free length.

Installation Notes

Die springs should be installed by qualified toolmakers or die maintenance personnel familiar with press tooling and spring retention systems. Always de-energize and lock out the press before servicing any die components. Do not compress the spring beyond its rated maximum operating deflection, as over-compression accelerates fatigue and can cause premature failure. Verify that the rod and hole clearances in the tooling match the spring dimensions before installation.
