Gibraltar DCIH40-64 Heavy-duty Die Spring Red 1565 Lb

Product Description

The GIBRALTAR DCIH40-64 is a heavy-duty die spring engineered for use in stamping dies, punch presses, and industrial tooling applications. Built from chromium alloy steel with a trapezoidal wire cross-section, it delivers a maximum deflection load of 1565 pounds and a spring rate of 1713 pounds per inch. The 2.5-inch free length compresses to a solid length at 0.91 inches, giving a maximum deflection of 0.91 inches. The red color coding identifies this as a heavy-duty unit per standard die spring classification. Toolmakers, die setters, and maintenance technicians install this spring as a direct replacement or in new tooling builds.

This spring fits standard die sets and guided spring assemblies that accept a 1.5-inch hole diameter and a 0.75-inch rod diameter. Its heavy-duty duty rating makes it appropriate for high-load, high-cycle stamping and forming operations in automotive, metal fabrication, and general manufacturing environments. The NAAMS and ISO 10243 ratings confirm dimensional and performance conformance for use in metric and inch-standard tooling platforms common in North American and international production facilities.

Key Features

• Maximum deflection load of 1565 pounds at 0.91 inches of travel
• Spring rate of 1713 pounds per inch for consistent, predictable force output
• Trapezoidal wire cross-section increases load capacity relative to round wire at the same envelope
• Chromium alloy steel construction for durability under repeated high-load cycling
• Red color coding identifies heavy-duty classification per die spring industry standards
• Meets NAAMS, ISO 10243, and ISO 9001:2015 registered quality standards

Compatibility

Designed as a standard-dimension die spring for guided spring assemblies requiring a 1.5-inch hole diameter and a 0.75-inch rod diameter, conforming to NAAMS and ISO 10243 dimensional standards for interchangeability with similarly rated die springs.

Installation Notes

Die springs are installed and replaced by toolmakers or maintenance technicians with the press or tooling equipment fully de-energized and the ram at the bottom of stroke or mechanically blocked. Inspect the spring pocket and guide rod for wear, scoring, or misalignment before installation. Do not compress the spring beyond its rated maximum deflection of 0.91 inches, as exceeding this value will accelerate fatigue failure. Consult applicable facility safety procedures and press manufacturer guidelines when servicing die tooling.
