Dayton Lamina 9-1612-36 Die Spring Extra Heavy-duty Yellow

Product Description

The DAYTON LAMINA 9-1612-36 is an extra heavy-duty die spring designed for use in stamping dies, punch presses, and precision tooling applications. Built from chromium-vanadium steel, it delivers reliable, consistent force under repeated compression cycles. The spring features a 1 inch hole diameter, a 1/2 inch rod diameter, and a 3 inch free length. Maximum deflection load is 534 pounds at 0.75 inches of travel, with a travel to solid load of 0.95 inches. The yellow color coding identifies the extra heavy-duty duty rating at a glance, following standard die spring color conventions. This part is sized and rated for demanding production tooling environments.

This die spring is used in metal stamping, forming, and progressive die applications where high cyclic loads and precise spring force are required. It seats on a 1/2 inch guide rod inside a 1 inch bore and is appropriate for both new die builds and replacement in existing tooling. Toolmakers, die setters, and maintenance technicians in automotive, fabrication, and industrial manufacturing facilities typically install and replace these springs during scheduled die maintenance or after signs of fatigue or set.

Key Features

• Extra heavy-duty rating with 534 pound maximum deflection load
• Chromium-vanadium steel construction for high-cycle fatigue resistance
• D-shaped wire cross-section for efficient space utilization inside the die pocket
• Yellow color coding for quick duty-rating identification per ISO standard convention
• 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 new-build die spring for stamping and forming dies requiring a 1 inch hole diameter, 1/2 inch rod diameter, and 3 inch free length in an extra heavy-duty application.

Installation Notes

Die springs should be installed by qualified toolmakers or die maintenance technicians familiar with press tooling safety procedures. Always relieve all press tonnage and lock out the press before removing or installing die springs. Inspect the guide rod and bore for wear or damage prior to installation. Do not exceed the rated maximum operating deflection, as overcompression accelerates fatigue and can lead to sudden failure.
