Gibraltar DCIL40-51 Die Spring 1-1/2in Light-duty Green

Product Description

The GIBRALTAR DCIL40-51 is a light-duty die spring designed for use in stamping dies, injection molds, and similar precision tooling applications. It features a 1-1/2 inch hole diameter, a 3/4 inch rod diameter, and a 2 inch free length. Constructed from chromium alloy steel with a trapezoidal wire profile, this spring delivers a maximum deflection load of 592 pounds at 0.99 inches of travel. The green color coding identifies it as a light-duty rating per industry standards. Toolmakers, die setters, and precision machining professionals are the primary installers.

This die spring is suited for light-duty press tooling, punch-and-die assemblies, stripper plate applications, and injection mold tooling where controlled spring force and consistent deflection are required. Its compact 2 inch free length and standard rod and hole dimensions make it a practical fit for tooling plates with 3/4 inch guide rods and 1-1/2 inch spring pockets. It is sold individually and carries a minimum order quantity of one unit.

Key Features

• Light-duty chromium alloy steel construction for consistent performance under cyclic load
• Trapezoidal wire cross-section for higher load capacity relative to round wire at comparable dimensions
• 1-1/2 inch hole diameter and 3/4 inch rod diameter for standard tooling plate fitment
• 592 pound maximum deflection load at 0.99 inches maximum deflection
• Spring rate of 597 pounds per inch for predictable force response
• Green color coding per NAAMS and ISO 10243 light-duty classification

Compatibility

Designed as an OEM-style replacement or direct fitment die spring for light-duty press tooling and mold assemblies using 1-1/2 inch spring pockets and 3/4 inch guide rods. Conforms to NAAMS (North American Automotive Metric Standard) and ISO 10243 international die spring standards.

Installation Notes

Die spring installation and replacement is typically performed by toolmakers or die maintenance technicians. Relieve all press and tooling pressure and lock out the press before removing or installing any die spring. Ensure the spring pocket depth and rod length are appropriate for the compressed length at maximum load of 0.99 inches to prevent coil bind. Do not exceed the rated maximum deflection during operation.
