Dayton Lamina 9-1614-36 Die Spring Extra Heavy-duty Yellow

Product Description

The DAYTON LAMINA 9-1614-36 is an extra heavy-duty die spring engineered for high-load stamping, forming, and tooling die applications. Built from chromium-vanadium steel, it delivers a maximum deflection load of 527 pounds with a maximum deflection of 0.88 inches. The D-shaped wire cross-section increases load-bearing surface area compared to round wire, allowing higher force output within a compact envelope. This spring features a 1 inch hole diameter, a 0.5 inch rod diameter, and a free length of 3.5 inches. Die maintenance technicians and tool-and-die professionals specify this spring where consistent, repeatable force and long fatigue life are required under sustained cycling loads.

This die spring is suited for use in metal stamping dies, punch and die assemblies, injection mold tooling, and progressive die sets in both production and maintenance environments. Its extra heavy-duty duty rating and yellow color coding make it straightforward to identify and replace during die servicing. The 25 percent maximum operating deflection limit should be respected during die design to maintain spring service life across high-cycle applications.

Key Features

• Extra heavy-duty duty rating with a maximum deflection load of 527 pounds
• Chromium-vanadium steel construction for high fatigue resistance and long service life
• D-shaped wire cross-section for increased load capacity in a compact form factor
• Yellow color coding for quick visual duty-rating identification in die sets
• Conforms to ISO 10243, ISO 9001:2015, and NAAMS standards for interchangeability and quality assurance
• Maximum operating deflection of 25 percent of free length to guide proper die design

Compatibility

Designed as an ISO 10243-compliant die spring replacement suitable for standard die spring pockets accepting a 1 inch hole diameter and 0.5 inch rod diameter in extra heavy-duty yellow-series applications.

Installation Notes

Die springs are installed and replaced by tool-and-die technicians and press maintenance personnel. Always relieve all press tonnage and de-energize the press before removing or installing die springs. Do not compress the spring beyond the maximum operating deflection of 25 percent during die operation, as over-compression reduces fatigue life significantly. Inspect the spring seat, pocket bore, and guide rod for wear or misalignment before installation to prevent premature failure.
