Gibraltar DCIL12.5-25 Die Spring Light-duty Green

Product Description

The GIBRALTAR DCIL12.5-25 is a light-duty die spring designed for use in metal stamping dies, tooling fixtures, and precision manufacturing applications. With a 0.5-inch hole diameter, a 9/32-inch (0.2813-inch) rod diameter, and a 1-inch free length, this spring fits standard die sets where controlled compression and consistent return force are required. It is manufactured from chromium alloy steel with a trapezoidal wire cross-section, which provides higher load capacity per unit length compared to round wire. The green color coding identifies the light-duty load range per ISO 10243 and NAAMS standards. Maximum deflection load is 66 pounds, and the spring rate is 106 pounds per inch.

This die spring is used in stamping, punching, bending, and forming dies across light manufacturing environments. It is suited for residential tooling shops, small-run production tooling, and maintenance replacement in existing die assemblies. The compact 1-inch free length and standard rod and hole dimensions make it a straightforward drop-in replacement in NAAMS-compliant and ISO 10243-compliant die configurations. Toolmakers, die maintenance technicians, and precision machinists are the primary installers of this component.

Key Features

• Chromium alloy steel construction with trapezoidal wire profile for consistent load performance
• Light-duty load rating with 66-pound maximum deflection load and 106 pounds per inch spring rate
• Green color coding per ISO 10243 and NAAMS light-duty classification
• 0.6200-inch maximum deflection with compressed length at maximum load of 0.62 inches
• Meets NAAMS, ISO 10243, and ISO 9001:2015 quality standards
• Compact 1-inch free length fits tight die cavities and short-stroke tooling

Compatibility

Designed as an OEM-style replacement for light-duty die spring positions in NAAMS-compliant and ISO 10243-compliant stamping and forming die assemblies requiring a 0.5-inch hole diameter and 9/32-inch rod diameter.

Installation Notes

Die springs should be installed by qualified toolmakers or die maintenance technicians with the press or tooling fixture fully de-energized and locked out per applicable machine safety procedures. Ensure the rod and hole diameters of the mounting pocket match the spring dimensions before installation. Do not exceed the rated maximum deflection of 0.6200 inches during operation, as over-compression will reduce service life and may damage the die assembly. Inspect the spring seat and pocket for burrs or damage before seating the replacement spring.
