Dayton Lamina 9-2412-11 Die Spring Light-duty Green

Product Description

The DAYTON LAMINA 9-2412-11 is a light-duty die spring designed for use in stamping dies, molds, and precision tooling applications. It features a 1-1/2 inch hole diameter, a 3/4 inch rod diameter, and a 3 inch free length, making it a compact, purpose-built compression spring for guided spring applications. Manufactured from chromium-vanadium steel, it delivers consistent load performance across repeated compression cycles. The D-shaped wire profile maximizes the load-bearing cross-section within a given outside diameter. Maximum deflection load is 449 pounds at 1.2 inches of maximum deflection, with a maximum operating deflection of 40 percent of free length.

This die spring is suited for use in progressive dies, injection molds, stamping presses, and fixture components where controlled, repeatable spring force is required. Its light-duty rating and green color coding follow ISO 10243 color classification, allowing toolmakers and die maintenance technicians to quickly identify duty class during setup and maintenance. It is appropriate for both original tooling builds and replacement service in existing die sets.

Key Features

• Chromium-vanadium steel construction for fatigue resistance under cyclic loading
• D-shaped wire profile for higher load capacity within the given envelope
• 1-1/2 inch hole diameter and 3/4 inch rod diameter for guided spring mounting
• Maximum deflection load of 449 pounds at 1.2 inches deflection
• Travel to solid load of 1.49 inches
• Green color coding per ISO 10243 light-duty classification

Compatibility

Designed as an ISO 10243-compliant light-duty die spring suitable for standard guided die spring applications requiring a 1-1/2 inch hole diameter, 3/4 inch rod diameter, and 3 inch free length.

Installation Notes

Die springs are installed by toolmakers and tool-and-die technicians during die builds or scheduled die maintenance. Always de-energize and lock out the press before servicing any die components. Confirm that the guide pin and bore diameters match the spring specifications before installation to prevent side loading, which shortens spring life. Do not compress the spring beyond the maximum operating deflection of 40 percent during normal operation.
