Dayton Lamina 9-1605-36 Die Spring Extra Heavy-duty Yellow

Product Description

The DAYTON LAMINA 9-1605-36 is an extra heavy-duty die spring designed for use in stamping dies, press tooling, and industrial mold applications. Built from chromium-vanadium steel, it delivers a maximum deflection load of 636 pounds over a maximum deflection of 0.31 inches. The spring features a D-shaped wire cross-section and a yellow color code that indicates its extra heavy-duty duty rating at a glance. With a free length of 1.25 inches, a 1-inch hole diameter, and a 0.5-inch rod diameter, it fits standard die sets without modification. Licensed toolmakers and die maintenance technicians are the primary installers of this component.

This die spring is suited for use in metal stamping, progressive die, and injection mold tooling where consistent, high-load spring force is required. The extra heavy-duty rating makes it appropriate for high-cycle press applications that demand reliable return force under repeated compression. Its compact free length fits tight die-set clearances in both single-station and progressive tooling layouts. The yellow color code allows quick visual identification during die maintenance without removing the spring from the set.

Key Features

• Extra heavy-duty duty rating with a maximum deflection load of 636 pounds
• Chromium-vanadium steel construction for high fatigue resistance under repeated cycling
• D-shaped wire cross-section for stable seating in standard die spring pockets
• Maximum operating deflection of 25 percent of free length
• Travel to solid load of 0.35 inches
• Meets ISO 10243, ISO 9001:2015, and NAAMS standards

Compatibility

Designed as an OEM-style replacement for extra heavy-duty die springs with a 1-inch hole diameter, 0.5-inch rod diameter, and 1.25-inch free length conforming to ISO 10243 and NAAMS dimensional standards.

Installation Notes

Die springs are installed by tool and die makers or qualified press maintenance personnel. Always de-energize and lock out the press before accessing the die set. Inspect the spring pocket and guide rod for wear or damage before installing a replacement spring. Do not compress the spring beyond its rated maximum operating deflection, as exceeding 25 percent of free length will accelerate fatigue failure.
