Gibraltar DCIH12.5-89 Heavy-duty Die Spring Red

Product Description

The GIBRALTAR DCIH12.5-89 is a heavy-duty die spring designed for use in stamping dies, molds, and industrial tooling applications where consistent, repeatable spring force is required. Built from chromium alloy steel with a trapezoidal wire cross-section, this spring delivers a maximum deflection load of 104 pounds and a spring rate of 63 pounds per inch. It features a 0.5-inch hole diameter and a 0.28125-inch rod diameter, with a free length of 3.5 inches and a maximum deflection of 1.65 inches. The red color designation indicates a heavy-duty load rating per ISO and NAAMS classification standards. This part is installed by toolmakers, die setters, and maintenance technicians in manufacturing and fabrication environments.

This die spring is suited for heavy-duty press tooling applications in both production stamping and prototype die work. The trapezoidal wire profile increases load capacity relative to round-wire springs of the same envelope, making it appropriate for high-cycle tooling where deflection consistency matters. It fits over a 0.28125-inch guide rod and seats in a 0.5-inch pocket, accommodating a compressed length of 1.65 inches at maximum load. Typical installations include stripper plates, blank holders, and cam returns in progressive and compound dies.

Key Features

• Heavy-duty load rating with 104-pound maximum deflection load at 1.65 inches of travel
• Trapezoidal wire cross-section for higher load capacity in a compact envelope
• Chromium alloy steel construction for durability and fatigue resistance in high-cycle tooling
• Spring rate of 63 pounds per inch for predictable, linear force output
• Red color coding per NAAMS and ISO 10243 heavy-duty classification for quick identification
• Meets NAAMS, ISO 10243, and ISO 9001:2015 registered quality standards

Compatibility

Designed as an OEM-style replacement or direct-fit die spring for heavy-duty stamping dies, injection molds, and industrial tooling using a 0.5-inch hole diameter and 0.28125-inch guide rod diameter with a 3.5-inch free length pocket.

Installation Notes

Die springs should be installed by qualified toolmakers or die maintenance technicians familiar with press tooling. Power down and de-energize the press completely before disassembling the die set or replacing springs. Ensure the guide rod diameter and pocket bore match the spring specifications before installation, and never compress the spring beyond its rated maximum deflection. Inspect the seating surfaces for burrs or damage that could cause uneven loading or premature spring failure.
