Gibraltar DCIM20-64 Die Spring Medium-duty Blue

Product Description

The GIBRALTAR DCIM20-64 is a medium-duty die spring designed for use in stamping dies, molds, and precision industrial fixtures. It features a trapezoidal wire cross-section that delivers higher load capacity in a compact envelope compared to round-wire springs of the same size. With a 0.75-inch hole diameter, a 0.375-inch rod diameter, and a 2.5-inch free length, this spring handles a maximum deflection load of 180 pounds at 1.02 inches of travel. It is manufactured from chromium alloy steel and color-coded blue for medium-duty classification per ISO 10243 and NAAMS standards. Licensed toolmakers, die setters, and machine builders typically specify and install this component.

This spring fits standard die sets and mold bases where a medium-duty blue-coded spring is called for under NAAMS or ISO 10243 guidelines. Typical applications include progressive stamping dies, injection mold ejector systems, and precision jigs where controlled return force and consistent spring rate are required. The 176 pounds-per-inch spring rate provides predictable, repeatable performance across production cycles. It is sold individually and is a direct replacement for worn or broken die springs in existing tooling that specifies a 0.75-inch bore, 0.375-inch rod, and 2.5-inch free length.

Key Features

• Trapezoidal wire profile increases load density compared to round-wire springs of the same dimensions
• Medium-duty blue color coding conforms to ISO 10243 and NAAMS classification standards
• Chromium alloy steel construction provides high fatigue resistance in cyclic die applications
• 176 pounds-per-inch spring rate delivers consistent, predictable deflection behavior
• 1.02-inch maximum deflection with a 180-pound maximum deflection load
• Meets ISO 9001:2015 quality management registration requirements

Compatibility

Designed as a standard replacement for medium-duty blue die springs conforming to ISO 10243 and NAAMS specifications with a 0.75-inch hole diameter, 0.375-inch rod diameter, and 2.5-inch free length.

Installation Notes

Die springs of this type are installed and replaced by licensed toolmakers or die setters during scheduled tooling maintenance. Always de-energize and lock out the press or machine before accessing the die set. Confirm that the rod diameter clearance and bore fit match the existing die pocket before seating the spring. Do not compress this spring beyond its rated maximum deflection, as overtravel accelerates fatigue failure.
