Gibraltar DCIM25-178 Die Spring 7 in Blue Medium-duty

Product Description

The GIBRALTAR DCIM25-178 is a medium-duty die spring engineered for use in stamping dies, molds, and industrial press tooling. Built from chromium alloy steel with a trapezoidal wire cross-section, this spring delivers consistent force across repeated compression cycles. It carries a maximum deflection load of 344 pounds over a maximum deflection of 2.99 inches, with a spring rate of 115 pounds per inch. The blue color coding indicates medium-duty classification per industry convention, making identification straightforward during tooling setup and maintenance. Licensed die makers, tooling technicians, and maintenance machinists are the primary installers.

This die spring is suited for precision tooling applications in stamping, injection molding, and progressive die operations. The 1-inch hole diameter accommodates standard die posts, and the 1/2-inch rod diameter ensures proper guided compression without buckling. With a 7-inch free length and a compressed length of approximately 2.99 inches at maximum load, it fits into tooling designs requiring moderate travel and controlled return force. Manufactured to NAAMS and ISO 10243 standards, it meets dimensional and load requirements common in both automotive and general industrial tooling environments.

Key Features

• Chromium alloy steel construction with trapezoidal wire cross-section for high-cycle fatigue resistance
• Medium-duty blue color coding per NAAMS and ISO 10243 classification
• Maximum deflection load of 344 pounds at 2.99 inches travel
• Spring rate of 115 pounds per inch for predictable, linear load response
• 1-inch hole diameter and 1/2-inch rod diameter for standard guided die post fitment
• Compliant with NAAMS, ISO 10243, and manufactured under ISO 9001:2015 registered quality systems

Compatibility

Designed as a standard replacement or new-build die spring for stamping dies, molds, and press tooling requiring a medium-duty spring with a 1-inch hole diameter, 1/2-inch rod diameter, and 7-inch free length per NAAMS and ISO 10243 dimensional standards.

Installation Notes

Die springs must be installed by qualified tooling technicians or die makers familiar with press tooling safety procedures. Always relieve all press tonnage and lock out the press before removing or installing springs in an active die set. Ensure the guide post and rod diameters match the spring bore and rod specifications to prevent lateral loading and premature fatigue. Inspect mating die components for wear or damage before installing a replacement spring.
