Gibraltar DCIL25-76 Die Spring 3 in Light-duty Green

Product Description

The GIBRALTAR DCIL25-76 is a light-duty die spring designed for use in stamping dies, molds, and tooling fixtures where controlled compression force is required. It features a 1-inch hole diameter, a 0.5-inch rod diameter, and a 3-inch free length. The spring is manufactured from chromium alloy steel with a trapezoidal wire cross-section, which improves load distribution and service life compared to round-wire designs. At maximum deflection of 1.59 inches, it delivers a load of 259 pounds. The green color coding follows standard industry practice for light-duty classification, making it easy to identify during assembly and maintenance.

This die spring is suited for light-duty tooling applications in stamping, forming, and injection mold setups. It fits standard die sets where a 1-inch bore and 0.5-inch guide rod are specified. Toolmakers, mold technicians, and maintenance machinists typically install and replace these springs during die rework or scheduled tooling maintenance. The compact free length of 3 inches makes it appropriate for shallow die pockets and confined tool assemblies.

Key Features

• Light-duty green color code per standard die spring classification
• Trapezoidal wire cross-section for improved load capacity and fatigue life over round-wire springs
• Chromium alloy steel construction for durability under repeated cycling
• Maximum deflection load of 259 pounds at 1.59 inches of travel
• Meets NAAMS, ISO 10243, and ISO 9001:2015 standards
• Spring rate of 163 pounds per inch for predictable, consistent force output

Compatibility

Designed as a standard replacement die spring for tooling fixtures and stamping dies requiring a 1-inch hole diameter, 0.5-inch rod diameter, and 3-inch free length in a light-duty application.

Installation Notes

Installation is typically performed by toolmakers or die maintenance technicians. Before replacing die springs, relieve all press tonnage and lock out the press per applicable machine safety procedures. Ensure the guide rod and bore are free of debris and within dimensional tolerance before seating the spring. Do not compress the spring beyond its rated maximum deflection of 1.59 inches, as exceeding this limit accelerates fatigue failure.
