Dayton Lamina 9-1607-21 Die Spring Blue Medium-duty

Product Description

The DAYTON LAMINA 9-1607-21 is a medium-duty die spring designed for use in metal stamping dies, press tooling, and similar industrial tooling applications. Built from chromium-vanadium steel with a D-shaped wire profile, this spring delivers a maximum deflection load of 309 pounds at a maximum deflection of 0.65 inches. The 1-inch hole diameter accommodates standard die posts, while the 1/2-inch rod diameter and 1-3/4-inch free length suit compact tooling setups. The blue color coding identifies it as a medium-duty spring per ISO 10243 color classification. Licensed toolmakers, die setters, and industrial maintenance technicians typically specify and install this component.

This die spring is suited for stamping dies, injection molds, stripping operations, and general press tooling where controlled, repeatable spring force is required. The medium-duty rating makes it appropriate for moderate-load cycling applications in both production and toolroom environments. Its compact free length of 1-3/4 inches fits space-constrained die assemblies. The D-shaped wire cross-section increases load capacity and reduces stress concentration compared to round wire designs of equivalent outer diameter.

Key Features

• Maximum deflection load of 309 pounds at full 0.65-inch deflection
• D-shaped chromium-vanadium steel wire for high load density and fatigue resistance
• 1-inch hole diameter and 1/2-inch rod diameter for standard die post fitment
• 1-3/4-inch free length suits compact tooling cavities
• Blue color coding per ISO 10243 medium-duty classification
• Meets ISO 10243, ISO 9001:2015, and NAAMS standards

Compatibility

Designed as an OEM-style replacement or new-build component for stamping dies and press tooling requiring a medium-duty die spring with a 1-inch hole diameter and 1/2-inch rod diameter per ISO 10243 dimensional standards.

Installation Notes

Die springs should be installed by qualified toolmakers or die setters familiar with press tooling safety procedures. Always relieve all press tonnage and lock out the press before disassembling or servicing a die assembly. Inspect the spring seat and guide post for wear or damage before installing a replacement spring. Do not compress the spring beyond the published maximum operating deflection to avoid permanent set or premature fatigue failure.
