Dayton Lamina 9-1207-11 Die Spring Light Duty Green

Product Description

The DAYTON LAMINA 9-1207-11 is a light-duty die spring engineered for use in stamping dies, molds, and press tooling applications. It features a 0.75-inch hole diameter and a 0.375-inch rod diameter, with a free length of 1.75 inches. Constructed from chromium-vanadium steel, this spring delivers consistent force and reliable fatigue life under cyclic loading. The D-shaped wire cross-section maximizes the spring's outer coil surface area for improved load distribution. It is color-coded green in accordance with ISO 10243 standards, indicating a light-duty load rating. Toolmakers, die setters, and press technicians install this part in production tooling environments.

This die spring is suited for light-duty stamping and forming dies in both prototype and production press applications. It is commonly installed in guided die sets where precise deflection control and repeatable spring return are required. The 1.75-inch free length and 0.6900-inch maximum deflection make it appropriate for applications with moderate travel requirements. It is compatible with standard die spring pockets and guided rod assemblies dimensioned to its 0.75-inch hole and 0.375-inch rod specifications.

Key Features

• Light-duty load rating with a maximum deflection load of 112.00 pounds
• Maximum operating deflection of 0.6900 inches, representing 40 percent of free length
• Travel to solid load of 0.8700 inches
• D-shaped wire cross-section for increased load surface contact
• Chromium-vanadium steel construction for fatigue resistance under cyclic press loads
• Green color coding per ISO 10243 for quick visual identification of duty rating

Compatibility

Designed as an OEM-style replacement or direct-fit die spring for standard light-duty die sets and press tooling requiring a 0.75-inch hole diameter, 0.375-inch rod diameter, and 1.75-inch free length per ISO 10243 specifications.

Installation Notes

Installation is performed by toolmakers or die maintenance technicians during die build or scheduled tooling maintenance. Power down and lock out the press completely before removing or replacing die springs. Ensure the guide rod diameter and pocket bore match the spring's specified rod and hole dimensions before seating the spring. Do not compress the spring beyond its travel-to-solid dimension during setup or operation.
