Gibraltar DCIH12.5-25 Heavy-duty Die Spring Red

Product Description

The GIBRALTAR DCIH12.5-25 is a heavy-duty die spring designed for use in stamping dies, punch presses, and precision tooling applications. It features a trapezoidal wire shape wound from chromium alloy steel, which provides consistent force output and extended cycle life under repetitive load conditions. The spring has a 0.5-inch hole diameter, a 0.28-inch rod diameter, and a 1-inch free length. It delivers a maximum deflection load of 107.00 pounds at 0.44 inches of travel, making it suitable for applications that demand reliable, high-force spring return. Licensed machinists, tool-and-die makers, and maintenance technicians are the primary installers.

This die spring is used in industrial tooling environments where controlled compression force and precise spring return are required. Typical applications include stamping and forming dies, injection mold components, jigs, and fixtures. The red color coding identifies it as a heavy-duty spring within standard die spring classification systems, consistent with NAAMS and ISO 10243 grading conventions. It is sold individually and is suited for both OEM tooling builds and maintenance replacement work in manufacturing facilities.

Key Features

• Trapezoidal wire cross-section for higher load capacity per unit length compared to round wire springs
• Maximum deflection load of 107.00 pounds at 0.44 inches of travel
• Spring rate of 242.00 pounds per inch for predictable, linear force output
• Chromium alloy steel construction for fatigue resistance under high-cycle conditions
• Red color coding indicates heavy-duty duty rating per NAAMS and ISO 10243 standards
• Meets NAAMS, ISO 10243, and ISO 9001:2015 standards

Compatibility

Designed as an OEM-style replacement or direct-fit component for stamping dies, punch press tooling, and precision fixture assemblies requiring a heavy-duty die spring with a 0.5-inch hole diameter, 0.28-inch rod diameter, and 1-inch free length.

Installation Notes

Installation is performed by qualified tool-and-die makers or industrial maintenance technicians. De-energize and fully lock out all press and tooling equipment before replacing any die spring. Verify that the mating hole diameter and rod diameter match the spring specifications before seating the spring to prevent misalignment or side-loading. Do not compress the spring beyond its rated maximum deflection of 0.44 inches, as overtravel can cause premature failure or tooling damage.
