Dayton Lamina 9-1008-36 Die Spring Extra Heavy-duty

Product Description

The DAYTON LAMINA 9-1008-36 is an extra heavy-duty die spring engineered for high-load tooling and stamping applications. It features a 0.625-inch hole diameter, an 11/32-inch rod diameter, and a 2-inch free length. Constructed from chromium-vanadium steel and color-coded yellow per ISO 10243 standards, this spring delivers consistent force output and fatigue resistance across repeated press cycles. The D-shaped wire profile maximizes contact surface area within the spring pocket, supporting stable seating and precise deflection control. Licensed tool and die technicians and toolroom machinists install this component in progressive dies, blanking dies, and similar metal-forming tooling.

This die spring suits tooling applications requiring extra heavy-duty load capacity. It handles a maximum deflection load of 159 pounds at 0.5 inches of maximum deflection, with a maximum operating deflection rating of 25 percent of free length. A travel-to-solid measurement of 0.65 inches defines the absolute compression limit. Typical use cases include die sets in stamping presses, injection mold components, and other precision tooling assemblies where consistent spring force and dimensional repeatability are critical to part quality and die longevity.

Key Features

• Extra heavy-duty duty rating with 159-pound maximum deflection load
• Chromium-vanadium steel construction for fatigue resistance under cyclic loading
• D-shaped wire profile for improved pocket seating and load distribution
• Yellow color coding per ISO 10243 for quick identification of duty class
• 2-inch free length with 0.5-inch maximum deflection and 0.65-inch travel to solid
• Meets ISO 10243, ISO 9001:2015, and NAAMS standards

Compatibility

Designed as an OEM-style replacement or direct-fit die spring for extra heavy-duty applications requiring a 0.625-inch hole diameter, 11/32-inch rod diameter, and 2-inch free length in ISO 10243 compliant tooling assemblies.

Installation Notes

Die springs are installed and replaced by tool and die technicians or toolroom maintenance personnel. Always relieve all press tonnage and lock out the press ram before accessing the die set. Inspect the spring pocket and guide rod for wear, scoring, or misalignment before seating the replacement spring. Do not compress the spring beyond its travel-to-solid length, as bottoming out accelerates fatigue failure.
