Dayton Lamina 9-3214-11 Die Spring Light-duty Green

Product Description

The DAYTON LAMINA 9-3214-11 is a light-duty die spring designed for use in stamping dies, press tooling, and industrial mold assemblies. It features a 2-inch hole diameter, a 1-inch rod diameter, and a free length of 3.5 inches. The spring is manufactured from chromium-vanadium steel with a D-shaped wire profile, which provides consistent load distribution and resistance to fatigue under repeated cycling. The green color coding identifies the light-duty load class per ISO 10243 standards. Maximum deflection load is 844 pounds at 1.4 inches of travel, with a travel-to-solid measurement of 1.74 inches. Licensed toolmakers, die setters, and maintenance technicians working in metal stamping and forming operations are the primary installers of this component.

This die spring is suited for light-duty applications in stamping and forming dies, injection mold assemblies, and similar press tooling where controlled spring force and precise deflection are required. Its ISO 10243 compliance makes it a standard fit for international tooling specifications. It is also aligned with NAAMS (North American Automotive Metric Standard) requirements, making it appropriate for automotive stamping die applications. The 40 percent maximum operating deflection rating guides engineers and toolmakers in selecting proper preload and working deflection during die design.

Key Features

• Light-duty load class with 844-pound maximum deflection load at 1.4 inches travel
• Chromium-vanadium steel construction for fatigue resistance under high-cycle press conditions
• D-shaped wire profile ensures consistent seating and load distribution
• Green color coding identifies load class per ISO 10243 international standard
• Meets ISO 9001:2015, ISO 10243, and NAAMS standards
• 40 percent maximum operating deflection rating for reliable die design reference

Compatibility

Designed as an ISO 10243-compliant light-duty die spring replacement for stamping dies, forming dies, and press tooling requiring a 2-inch hole diameter and 1-inch rod diameter with a 3.5-inch free length.

Installation Notes

Die spring replacement and installation should be performed by qualified toolmakers or die setters with the press fully de-energized, locked out, and the slide blocked before any tooling access. Inspect the die pocket and guide rod for wear or damage before installing the new spring. Do not exceed the 40 percent maximum operating deflection rating during die setup, as over-deflection reduces spring service life and can lead to premature failure. Follow applicable shop safety procedures and tooling design specifications for preload and working deflection values.
