Gibraltar DCIM12.5-76 Die Spring 3 in Blue Medium-duty

Product Description

The GIBRALTAR DCIM12.5-76 is a medium-duty die spring designed for use in stamping dies, molds, and tooling fixtures where controlled compression force is required. Built from chromium alloy steel with a trapezoidal wire profile, it delivers a maximum deflection load of 76 pounds and a spring rate of 50 pounds per inch. The 0.5-inch hole diameter accommodates a 9/32-inch rod, and the 3-inch free length compresses to a solid length of 1.54 inches at maximum load. Identified by its blue color coding for medium-duty classification, this spring meets NAAMS, ISO 10243, and ISO 9001:2015 standards. It is typically installed by tool-and-die technicians, press operators, or maintenance professionals servicing industrial stamping equipment.

This die spring is suited for medium-load tooling applications in automotive, manufacturing, and general fabrication environments. The trapezoidal wire cross-section maximizes force output within the envelope of the coil geometry, making it efficient where space is constrained inside a die set or mold assembly. The blue color coding allows quick visual identification of duty rating during tool changeouts or press maintenance, reducing the risk of substituting incorrect spring rates in multi-spring die sets.

Key Features

• Chromium alloy steel construction for durability under repeated cycling
• Trapezoidal wire shape for higher load capacity in a compact envelope
• Blue color-coded for medium-duty classification per NAAMS and ISO 10243 standards
• Maximum deflection load of 76 pounds with a spring rate of 50 pounds per inch
• Free length of 3 inches compresses to 1.54 inches at maximum load
• Compliant with NAAMS, ISO 10243, and ISO 9001:2015 quality standards

Compatibility

Designed as an OEM-style replacement or direct-fit die spring for medium-duty stamping dies, molds, and tooling fixtures that accept a 0.5-inch hole diameter and 9/32-inch guide rod with a 3-inch free length.

Installation Notes

Die spring replacement and installation is performed by qualified tool-and-die technicians or maintenance personnel with knowledge of press tooling. Always de-energize and lock out the press before accessing the die set. Ensure the guide rod diameter is compatible with the 9/32-inch rod specification to prevent lateral loading and premature spring fatigue. Do not compress the spring beyond its maximum deflection of 1.54 inches, as operating past the rated travel-to-solid load will reduce service life.
