Gibraltar DCIM12.5-38 Die Spring Medium-duty Blue

Product Description

The GIBRALTAR DCIM12.5-38 is a medium-duty die spring designed for use in stamping dies, molds, and precision tooling fixtures. Built from chromium alloy steel with a trapezoidal wire cross-section, it delivers a spring rate of 107 pounds per inch and a maximum deflection load of 84 pounds at 0.78 inches of travel. The blue color coding identifies it as medium-duty per standard die spring classification. This part is installed by tool and die makers, machine builders, and maintenance technicians working on press tooling and industrial automation equipment.

This die spring is suited for use in stamping dies, injection molds, jigs, fixtures, and similar precision tooling applications where consistent, repeatable spring force is required. The 0.5-inch hole diameter accepts a rod diameter of 0.2813 inches (9/32 inches), and the 1.5-inch free length fits medium-stroke tooling setups. It is a direct-fit replacement in applications requiring NAAMS or ISO 10243 standard medium-duty blue die springs.

Key Features

• Medium-duty rating with blue color coding per NAAMS and ISO 10243 standard classification
• Trapezoidal wire profile provides higher load capacity and longer fatigue life compared to round wire springs
• Spring rate of 107 pounds per inch for predictable, linear force output
• Maximum deflection load of 84 pounds at 0.78 inches travel
• Chromium alloy steel construction for durability in high-cycle tooling environments
• Meets NAAMS, ISO 10243, and ISO 9001:2015 registered quality standards

Compatibility

Designed as an OEM-style replacement for medium-duty die spring positions requiring a 0.5-inch hole diameter, 9/32-inch rod diameter, and 1.5-inch free length per NAAMS and ISO 10243 specifications.

Installation Notes

Installation is performed by tool and die technicians or machine maintenance personnel. De-energize and lock out all press and tooling equipment before servicing die components. Ensure the mating rod diameter does not exceed 0.2813 inches and that the bore diameter matches 0.5 inches to prevent side loading or premature fatigue. Do not compress the spring beyond its rated maximum deflection of 0.78 inches.
