Gibraltar DCIH12.5-38 Heavy-duty Die Spring Red

Product Description

The GIBRALTAR DCIH12.5-38 is a heavy-duty die spring engineered for use in stamping dies, punch presses, and other tooling applications where consistent, high-force compression cycling is required. Built from chromium alloy steel with a trapezoidal wire cross-section, this spring delivers a maximum deflection load of 107 pounds at 0.69 inches of travel. The red color coding indicates heavy-duty duty rating per industry convention, allowing for quick identification during die assembly and maintenance. It is installed by tool and die makers, maintenance technicians, and industrial machine technicians working on metal forming equipment.

This spring is suited for use in stamping dies, progressive dies, and similar tooling setups requiring a compact, high-load spring element. With a 0.5-inch hole diameter and 9/32-inch rod diameter, it fits standard die set guide posts and spring pockets commonly found in light to medium industrial tooling. The 1.5-inch free length makes it appropriate for applications with limited vertical clearance in the die stack. It meets NAAMS, ISO 10243, and ISO 9001:2015 standards, making it compatible with automotive tooling specifications.

Key Features

• Heavy-duty duty rating with 107-pound maximum deflection load at full 0.69-inch travel
• Trapezoidal wire cross-section provides higher load capacity per unit length compared to round wire
• Chromium alloy steel construction for fatigue resistance under repeated cycling
• Red color coding for immediate duty-rating identification per NAAMS and ISO 10243 conventions
• Spring rate of 154 pounds per inch for predictable, linear force delivery
• Meets NAAMS, ISO 10243, and ISO 9001:2015 standards for use in automotive and industrial tooling

Compatibility

Designed as a replacement or new-installation die spring for stamping dies, punch presses, and progressive die tooling applications conforming to NAAMS and ISO 10243 standard spring pocket dimensions with a 0.5-inch hole diameter and 9/32-inch rod diameter.

Installation Notes

Installation is typically performed by tool and die makers or industrial maintenance technicians during die build or scheduled tooling maintenance. De-energize and lock out all press energy sources before removing or installing die springs. Ensure the spring pocket depth and guide rod diameter match the spring specifications before seating. Do not exceed the rated maximum deflection of 0.69 inches, as compressing beyond solid height will cause permanent deformation and premature failure.
