Gibraltar DCIM12.5-32 Die Spring Medium-duty Blue

Product Description

The GIBRALTAR DCIM12.5-32 is a medium-duty die spring engineered for use in stamping dies, injection molds, and industrial press tooling. It features a trapezoidal wire cross-section wound from chromium alloy steel, which delivers higher load capacity per unit length compared to round-wire designs. The spring accepts a 0.5-inch hole diameter and a 0.28125-inch rod diameter, with a 1.25-inch free length. At maximum deflection of 0.65 inches, it sustains a load of 84 pounds. A spring rate of 128 pounds per inch provides consistent, predictable resistance across the compression stroke. Licensed HVAC, tool-and-die, and industrial maintenance technicians specify this part for precision tooling applications.

This die spring is suited for medium-duty press and mold applications where controlled deflection and repeatable load characteristics are required. Its blue color coding follows standard die spring color conventions for quick duty-rating identification in the shop. Typical install scenarios include stripper plates, die sets, mold ejector systems, and spring-loaded fixtures in both production and prototype tooling environments. The compact 1.25-inch free length makes it appropriate for tooling with limited daylight or shallow spring pockets.

Key Features

• Medium-duty rating with a spring rate of 128 pounds per inch for consistent load response
• Trapezoidal wire cross-section maximizes load capacity within the coil envelope
• Chromium alloy steel construction for fatigue resistance and dimensional stability under repeated cycling
• Blue color coding for fast duty-rating identification per industry die spring standards
• 0.5-inch hole diameter and 0.28125-inch rod diameter for straightforward pocket and rod fitment
• Meets NAAMS, ISO 10243, and ISO 9001:2015 standards

Compatibility

Designed as an OEM-style replacement or new-installation die spring for medium-duty stamping dies, injection molds, and spring-loaded industrial tooling requiring a 0.5-inch hole diameter and 1.25-inch free length.

Installation Notes

Installation is typically performed by tool-and-die makers or industrial maintenance technicians. Power down and lock out all press or mold equipment before replacing die springs. Verify that the spring pocket depth and rod length accommodate the free length and compressed length at maximum load before seating the spring. Do not exceed the rated maximum deflection of 0.65 inches, as over-compression reduces fatigue life and can cause premature failure.
