Gibraltar DCIH12.5-64 Die Spring 2.5 in Heavy Duty Red

Product Description

The GIBRALTAR DCIH12.5-64 is a heavy-duty die spring designed for use in stamping dies, molds, and industrial tooling applications where reliable, consistent return force is required. Built from chromium alloy steel with a trapezoidal wire cross-section, it delivers a maximum deflection load of 100 pounds with a spring rate of 87 pounds per inch. The 0.5-inch hole diameter and 0.281-inch rod diameter allow straightforward fitment over standard guide rods. This spring is color-coded red, indicating heavy-duty duty rating per industry convention. Installation is typically performed by tool and die makers, machine builders, or maintenance technicians working on press tooling and automated fixtures.

This die spring is suited for heavy-duty industrial tooling environments including stamping dies, injection molds, and mechanical presses. The 2.5-inch free length compresses to a solid length of 1.15 inches, providing 1.15 inches of maximum deflection travel. Applications include stripper plates, lifter mechanisms, and cam-return assemblies in production tooling where space constraints and load requirements demand a compact, high-force spring.

Key Features

• Heavy-duty duty rating with 100-pound maximum deflection load (445 newtons)
• Trapezoidal wire cross-section provides higher load capacity versus round wire of the same envelope
• Chromium alloy steel construction for fatigue resistance under repeated cycling
• Spring rate of 87 pounds per inch for predictable, linear force response
• Red color-coding for quick visual identification of heavy-duty rating in mixed tooling environments
• Meets NAAMS, ISO 10243, and ISO 9001:2015 standards

Compatibility

Designed as a standard heavy-duty die spring conforming to NAAMS and ISO 10243 dimensional standards, suitable for use in stamping dies, molds, and tooling fixtures with a 0.5-inch hole diameter and 0.281-inch rod diameter guide configuration.

Installation Notes

Die spring installation and replacement should be performed by qualified tool and die technicians or maintenance personnel with the press or machine de-energized and all stored mechanical energy relieved before disassembly. Inspect the mating guide rod and bore for wear or misalignment prior to installation, as side loading significantly reduces spring service life. Do not exceed the rated maximum deflection of 1.15 inches during operation. Refer to applicable machine safety standards and the tooling OEM documentation for proper preload and assembly procedures.
