Dayton Lamina 9-1204-11 Die Spring 3/4in Light-duty Green

Product Description

The DAYTON LAMINA 9-1204-11 is a light-duty die spring designed for use in stamping dies, press tooling, and similar industrial tooling applications. It features a 3/4 inch hole diameter, a 3/8 inch rod diameter, and a 1 inch free length. Manufactured from chromium-vanadium steel with a D-shaped wire profile, this spring delivers consistent force and durability under cyclic compression loads. It carries a maximum deflection load of 126 pounds at 0.4 inch maximum deflection, representing a 40 percent operating deflection range. The green color coding identifies it as a light-duty rating per ISO 10243 standards. This part is sold individually.

The 9-1204-11 is suited for use in metal stamping dies, injection mold components, and precision tooling fixtures where controlled spring force and repeatable travel are required. Its compact 1 inch free length and standard hole and rod dimensions make it a practical fit in tight die sets. It is typically installed by tool and die makers, machinists, and maintenance technicians working on press tooling in manufacturing and fabrication environments. The spring meets ISO 10243 international die spring standards and NAAMS dimensional requirements, making it directly interchangeable in metric and North American tooling layouts.

Key Features

• Light-duty chromium-vanadium steel construction for consistent cyclic performance
• D-shaped wire profile for stable seating and anti-rotation in die sets
• 126 pound maximum deflection load at 0.4 inch maximum deflection
• 40 percent maximum operating deflection range for controlled travel
• Green color coding identifies light-duty rating per ISO 10243
• Meets ISO 10243, ISO 9001:2015, and NAAMS standards

Compatibility

Designed as a standard replacement or new-installation die spring for tooling applications conforming to ISO 10243 international die spring dimensions and NAAMS specifications.

Installation Notes

Die springs should be installed by qualified tool and die makers or maintenance technicians with the press fully locked out and de-energized before any die set work begins. Ensure the rod diameter and hole diameter clearances match the die set design before installation. Do not exceed the rated maximum operating deflection of 40 percent during service, as operating beyond this limit accelerates fatigue failure. Inspect springs periodically for cracking, set, or corrosion and replace in matched sets where tooling design requires it.
