Dayton Lamina 9-2024-21 Die Spring 6 Inch Blue Medium-duty

Product Description

The DAYTON LAMINA 9-2024-21 is a medium-duty die spring engineered for use in metal stamping dies, molds, and industrial tooling applications. Built from chromium-vanadium steel and color-coded blue for quick duty-rating identification, this spring features a 1-1/4 inch hole diameter, a 5/8 inch rod diameter, and a free length of 6 inches. It delivers a maximum deflection load of 438 pounds at 2.24 inches of maximum deflection, with a travel to solid load of 2.53 inches. The D-shaped wire cross-section maximizes coil contact area and improves load consistency over the spring's service life.

This spring is suited for press tool and die applications in industrial manufacturing environments. It is commonly installed in progressive dies, blanking dies, and injection mold assemblies where controlled, repeatable spring force is required. The blue color coding identifies this unit as a medium-duty spring, enabling fast sorting and replacement on the shop floor or in the tool room. It conforms to ISO 10243 dimensional standards, making it interchangeable with other ISO-spec die springs of matching geometry.

Key Features

• Chromium-vanadium steel construction for high fatigue resistance under cyclic loading
• D-shaped wire cross-section increases load-bearing surface area and load consistency
• Blue color code identifies medium-duty rating at a glance
• Maximum deflection load of 438 pounds at 2.24 inches deflection
• Maximum operating deflection of 37.50 percent of free length
• Conforms to ISO 10243, ISO 9001:2015, and NAAMS standards

Compatibility

Designed as an ISO 10243-compliant die spring replacement for medium-duty press tool and mold applications requiring a 1-1/4 inch hole diameter and 5/8 inch rod diameter with a 6 inch free length.

Installation Notes

Die spring installation and replacement is typically performed by toolmakers or maintenance technicians working on stamping presses and injection mold equipment. Always de-energize and lock out the press or machine before accessing the die set. Do not compress the spring beyond the rated maximum operating deflection, as exceeding 37.50 percent of free length will accelerate fatigue failure. Verify rod and hole clearances match the spring dimensions before installation.
