Dayton Lamina 9-1014-36 Die Spring Yellow Extra Heavy-duty

Product Description

The DAYTON LAMINA 9-1014-36 is an extra heavy-duty die spring designed for use in metal stamping dies, molds, and tooling fixtures. Built from chromium-vanadium steel, it delivers high load capacity and consistent return force across repeated compression cycles. The spring features a D-shaped wire cross-section and a yellow color designation indicating extra heavy-duty load class per ISO 10243. Key dimensions include a 0.625-inch hole diameter, an 11/32-inch rod diameter, and a 3.5-inch free length. Maximum deflection load is 152 pounds at 0.88 inches of travel. This component is installed and specified by toolmakers, die setters, and maintenance technicians working with stamping and forming equipment.

This die spring is suited for industrial tooling applications including stamping dies, injection molds, punch and die assemblies, and fixture clamping systems. The extra heavy-duty rating makes it appropriate for high-load, high-cycle environments where standard or medium-duty springs would fail prematurely. Its ISO 10243 compliance means it is dimensionally interchangeable with other ISO-standard die springs of the same size class, and it also meets NAAMS dimensional requirements, which are common in North American automotive tooling programs.

Key Features

• Extra heavy-duty load class indicated by yellow color per ISO 10243
• Chromium-vanadium steel construction for high fatigue resistance in repetitive-cycle applications
• D-shaped wire cross-section for precise seating and consistent load distribution
• Maximum deflection load of 152 pounds at 0.88 inches travel
• Maximum operating deflection rated at 25 percent of free length
• Meets ISO 10243, ISO 9001:2015, and NAAMS standards

Compatibility

Dimensionally compliant with ISO 10243 and NAAMS standards, making this spring a direct interchange for ISO-standard extra heavy-duty die springs with a 0.625-inch hole diameter and 3.5-inch free length in stamping and mold tooling assemblies.

Installation Notes

Die springs should be installed by qualified toolmakers or die maintenance technicians familiar with press tooling safety procedures. Before replacing a spring, the press or mold must be fully de-energized, blocked, and relieved of stored mechanical energy. Do not compress a die spring beyond its rated maximum operating deflection, as overtravel accelerates fatigue and can cause sudden failure. Ensure the mating rod and pocket dimensions are within tolerance for the specified rod diameter and hole diameter of this spring.
