Gibraltar DCIM12.5-25 Die Spring Medium-duty Blue

Product Description

The GIBRALTAR DCIM12.5-25 is a medium-duty die spring designed for use in stamping dies, molds, and precision tooling applications. Built from chromium alloy steel with a trapezoidal wire cross-section, it delivers consistent load performance and extended service life under cyclic compression. The spring features a 0.5 inches hole diameter, a 9/32 inches (0.2813 inches) rod diameter, and a 1 inch free length. At maximum deflection of 0.5000 inches, it generates a load of 84 pounds. The blue color coding indicates medium-duty classification per standard die spring conventions. Machinists, tool and die makers, and maintenance technicians working on stamping or injection mold tooling are the primary installers.

This die spring is suited for medium-duty cycling applications in stamping dies, progressive dies, injection molds, and similar precision tooling where repeatable spring force and compact envelope size are required. Its 1 inch free length and 0.5 inches hole diameter make it appropriate for applications with limited cavity depth. The trapezoidal wire profile maximizes wire cross-section within the coil, improving load capacity and fatigue resistance compared to round wire springs of equivalent size.

Key Features

• Medium-duty classification with 84 pounds maximum deflection load (373.80 N)
• Trapezoidal wire cross-section for improved load density and fatigue life
• Chromium alloy steel construction for durability under cyclic loading
• 0.5000 inches maximum deflection with a compressed solid length of 0.5 inches
• Spring rate of 168 pounds per inch for predictable, linear force output
• Blue color coding for quick medium-duty identification in tooling assemblies
• Meets NAAMS, ISO 10243, and ISO 9001:2015 standards

Compatibility

Designed as a standard replacement or new-installation die spring for medium-duty stamping dies, injection molds, and precision tooling assemblies requiring a 0.5 inches hole diameter and 1 inch free length per NAAMS and ISO 10243 dimensional standards.

Installation Notes

Installation is typically performed by tool and die makers or maintenance machinists during die build or scheduled tooling maintenance. Always relieve all press or clamp pressure and de-energize the associated equipment before removing or seating die springs. Confirm rod diameter clearance and hole diameter seating before compressing the spring assembly. Do not exceed the specified maximum deflection of 0.5000 inches, as operating beyond travel-to-solid limits accelerates fatigue failure.
