Dayton Lamina 9-0807-11 Die Spring Light Duty Green

Product Description

The DAYTON LAMINA 9-0807-11 is a light-duty die spring designed for use in stamping dies, molds, and tooling fixtures where consistent, reliable spring force is required. Built from chromium-vanadium steel, this spring features a D-shaped wire cross-section and is color-coded green to indicate its light-duty rating, following ISO 10243 conventions. It has a 0.5-inch hole diameter, a 9/32-inch rod diameter, and a free length of 1.75 inches. The maximum deflection load is 46 pounds at 0.69 inches of travel, making it suitable for applications requiring controlled, low-force actuation within a compact form factor.

This die spring is used in press tooling, injection molds, and progressive die assemblies where light stripping or pad pressure is needed. Its ISO 10243-compliant dimensions make it a direct fit in standard die sets that specify green-series light-duty springs. The D-shaped wire profile maximizes surface contact within the bore for improved load distribution and fatigue life. Toolmakers, die setters, and mold technicians typically specify this spring during tool builds or maintenance cycles.

Key Features

• Light-duty green series per ISO 10243 International Standard
• Chromium-vanadium steel construction for fatigue resistance
• D-shaped wire cross-section for increased load contact area
• Maximum deflection load of 46 pounds at 0.69 inches travel
• 40 percent maximum operating deflection rating
• Meets ISO 9001:2015 and NAAMS dimensional standards

Compatibility

Designed as an ISO 10243-compliant light-duty die spring for use in standard tooling bores requiring a 0.5-inch hole diameter and 9/32-inch rod diameter. Compatible with die sets and mold bases specifying green-series springs at 1.75-inch free length.

Installation Notes

Die springs should be installed by qualified toolmakers or die setters with the tooling fully de-energized and press ram locked out per applicable lockout/tagout procedures. Do not compress the spring beyond the rated maximum operating deflection of 40 percent during service. Inspect the spring seating surfaces for burrs or misalignment before installation to prevent premature fatigue failure. Replace springs in matched sets when possible to maintain consistent load balance across the die.
