Dayton Lamina 9-0604-36 Die Spring 1 in Extra Heavy-duty

Product Description

The DAYTON LAMINA 9-0604-36 is an extra heavy-duty die spring designed for precision tooling and stamping die applications. It features a 3/8-inch hole diameter, a 3/16-inch rod diameter, and a free length of 1 inch. Constructed from chromium-vanadium steel with a D-shaped wire cross-section, this spring delivers consistent force and fatigue resistance under repeated cycling. The yellow color coding identifies it as an extra heavy-duty rating per ISO 10243 standards, making it straightforward to sort and specify on the shop floor. A maximum deflection load of 46 pounds and a maximum deflection of 0.29 inches define its working envelope.

This die spring is suited for use in metal stamping dies, punch and die tooling, and fixture applications where high load capacity is required in a compact envelope. It is typically installed and specified by tool and die makers, mold builders, and precision fabrication shops. The 1-inch free length makes it appropriate for tight-clearance die sets where space is limited but load requirements remain demanding.

Key Features

• Extra heavy-duty duty rating with yellow color coding per ISO 10243
• Chromium-vanadium steel construction for fatigue resistance under cyclic loading
• D-shaped wire cross-section for consistent seating and load distribution
• Maximum deflection load of 46 pounds at 0.29 inches of travel
• Maximum operating deflection of 25 percent of free length
• Meets ISO 10243, ISO 9001:2015, and NAAMS standards

Compatibility

Designed as an OEM-style replacement or direct-fit component for standard die spring pockets accepting a 3/8-inch hole diameter and 3/16-inch rod diameter in extra heavy-duty tooling applications.

Installation Notes

Die springs of this type are installed by tool and die makers during die build or maintenance. Always relieve all press pressure and lock out the press before replacing springs in a die set. Inspect the spring pocket and rod for wear or damage before installing a new spring. Do not compress the spring beyond its rated maximum deflection to avoid premature failure or set.
