Dayton Lamina 9-0612-11 Die Spring 3 Inch Light-duty Green

Product Description

The DAYTON LAMINA 9-0612-11 is a light-duty die spring designed for use in stamping dies, punch press tooling, and similar metal-forming fixtures. It features a 3/8 inch hole diameter and a 3/16 inch rod diameter, with a 3 inch free length. The spring is manufactured from chromium-vanadium steel and color-coded green to indicate its light-duty rating, making fast visual identification straightforward during tool setup and maintenance. A maximum deflection load of 25 pounds and a maximum deflection of 1.2 inches define its working envelope. Licensed toolmakers and die maintenance technicians are the primary installers of this component.

This spring is suited for light-load applications in stamping dies, progressive dies, and similar metal-forming tooling found in automotive, industrial, and general manufacturing environments. The green color coding follows the widely recognized die spring duty classification system, allowing rapid sorting and replacement during scheduled tooling maintenance. Its D-shaped wire cross-section improves load efficiency and space utilization within tight die cavities.

Key Features

• Light-duty rating with green color coding for fast visual identification
• Chromium-vanadium steel construction for fatigue resistance in cyclic loading applications
• D-shaped wire cross-section for improved load capacity per unit of space
• 3 inch free length with 1.2 inch maximum deflection (40 percent maximum operating deflection)
• Maximum deflection load of 25 pounds; travel to solid load of 1.81 inches
• Meets ISO 10243 International Standard, ISO 9001:2015, and NAAMS requirements

Compatibility

Designed as an OEM-style replacement or direct-fit component for light-duty die spring positions in stamping and metal-forming tooling requiring a 3/8 inch hole diameter, 3/16 inch rod diameter, and 3 inch free length per ISO 10243 specifications.

Installation Notes

Installation is performed by toolmakers or die maintenance technicians during press setup or scheduled tooling service. Always de-energize and lockout the press before accessing the die set. Confirm hole and rod diameters match the die pocket and guide pin dimensions before seating the spring. Do not compress the spring beyond its rated maximum operating deflection of 40 percent to avoid premature fatigue failure.
