Dayton Lamina 9-1206-21 Die Spring 1.5 in Blue Medium-duty

Product Description

The DAYTON LAMINA 9-1206-21 is a medium-duty die spring designed for use in stamping dies, punch presses, and related tooling applications. It features a 0.75 inch hole diameter, a 0.375 inch rod diameter, and a 1.5 inch free length. Constructed from chromium-vanadium steel with a D-shaped wire profile, this spring delivers a maximum deflection load of 176.00 pounds at 0.56 inch maximum deflection. The blue color coding identifies its medium-duty rating per ISO 10243 standards. Licensed die makers, tool and die technicians, and press room maintenance personnel are the primary installers.

This die spring is suited for metal stamping, forming, and blanking operations in both production and maintenance tooling environments. Its medium-duty classification makes it appropriate for moderate-load applications where controlled return force and consistent stroke are required. The 37.50 percent maximum operating deflection and 0.61 inch travel-to-solid value support predictable performance in high-cycle press tooling.

Key Features

• Medium-duty rating with blue color coding per ISO 10243 international standard
• Chromium-vanadium steel construction for fatigue resistance in cyclic loading
• D-shaped wire profile for consistent seating and alignment on rod or in hole
• Maximum deflection load of 176.00 pounds at 0.56 inch deflection
• 37.50 percent maximum operating deflection with 0.61 inch travel to solid
• ISO 9001:2015 registered manufacturing and NAAMS compliant

Compatibility

Designed as a standard replacement or new-installation die spring for tooling applications conforming to ISO 10243 and NAAMS dimensional standards where a 0.75 inch hole diameter and 0.375 inch rod diameter are specified.

Installation Notes

Die springs should be installed by qualified tool and die technicians or press room maintenance personnel familiar with stamping tooling assembly. Always relieve all press pressure and lock out the press before servicing die components. Do not exceed the rated maximum operating deflection, as running a die spring to solid accelerates fatigue failure. Inspect seating surfaces on the rod and in the die pocket for burrs or damage before installation.
