Gibraltar DCIH25-152 Heavy-duty Die Spring Red

Product Description

The GIBRALTAR DCIH25-152 is a heavy-duty die spring engineered for use in stamping dies, punch presses, and precision tooling applications. Built from chromium alloy steel with a trapezoidal wire cross-section, it delivers a maximum deflection load of 658 pounds and a spring rate of 303 pounds per inch. The 6-inch free length compresses to a solid length of approximately 2.17 inches, providing 2.17 inches of maximum deflection. The red color coding denotes heavy-duty load classification per industry standards. This spring is installed and serviced by tool and die makers, press operators, and maintenance technicians working in metal fabrication and stamping environments.

This die spring is suited for use in industrial die sets, mold bases, and mechanical press tooling where high load capacity and consistent return force are required. Its trapezoidal wire profile increases load-bearing area compared to round wire springs of the same envelope size, making it appropriate for high-cycle stamping operations. The 1-inch hole diameter and 0.5-inch rod diameter allow straightforward integration into standard die set guide pin configurations.

Key Features

• Heavy-duty load rating with a maximum deflection load of 658 pounds (2928.10 Newtons)
• Trapezoidal wire cross-section for increased load capacity within a compact envelope
• Chromium alloy steel construction for durability in high-cycle applications
• Red color coding identifies heavy-duty duty class for quick field identification
• Meets NAAMS, ISO 10243, and ISO 9001:2015 standards
• Spring rate of 303 pounds per inch for predictable, consistent force output

Compatibility

Designed as a standard replacement die spring compatible with die sets and tooling assemblies specifying a 1-inch hole diameter, 0.5-inch rod diameter, and 6-inch free length in heavy-duty (red) classification per ISO 10243 and NAAMS dimensional standards.

Installation Notes

Installation is typically performed by tool and die technicians or press room maintenance personnel. Always relieve all mechanical pressure and lock out the press before servicing die components. Ensure the guide rod and bore dimensions match the spring specifications before installation. Do not exceed the rated maximum deflection of 2.17 inches during operation, as compressing beyond this point can cause permanent set or spring failure.
