Gibraltar DCIH25-64 Die Spring Heavy-duty Red

Product Description

The GIBRALTAR DCIH25-64 is a heavy-duty die spring designed for use in stamping dies, presses, and tooling fixtures that require reliable, consistent force under repeated compression cycles. Built from chromium alloy steel with a trapezoidal wire cross-section, this spring delivers a maximum deflection load of 603 pounds at 0.83 inches of maximum deflection. The spring rate is 726 pounds per inch, making it suitable for applications that demand precise, repeatable load characteristics. Licensed trades and tooling professionals working in die maintenance, metal fabrication, or industrial press operations will find this spring meets standard dimensional and performance requirements for drop-in replacement or new tooling builds.

This die spring is suited for use in metal stamping dies, injection mold tooling, and general industrial press assemblies where heavy-duty duty ratings are required. The red color designation indicates the heavy-duty load class per ISO 10243 and NAAMS standards, helping technicians quickly identify the correct spring during assembly or changeover. With a 1 inch hole diameter and 0.5 inch rod diameter, it fits standard die components without modification.

Key Features

• Heavy-duty duty rating with a maximum deflection load of 603 pounds
• Chromium alloy steel construction with trapezoidal wire shape for high fatigue resistance
• Spring rate of 726 pounds per inch for consistent, predictable force output
• 1 inch hole diameter and 0.5 inch rod diameter for standard die fitment
• Red color coding per ISO 10243 and NAAMS heavy-duty class identification
• Meets NAAMS, ISO 10243, and ISO 9001:2015 standards

Compatibility

Designed as a standard heavy-duty die spring replacement or new-build component for metal stamping dies, mold tooling, and industrial press fixtures that accept a 1 inch hole diameter and 0.5 inch rod diameter with a 2.5 inch free length.

Installation Notes

Installation should be performed by a qualified tooling technician or die maintenance professional. Power down and lock out all press and hydraulic equipment before servicing any die components. Ensure the rod and bore dimensions of the die pocket match the spring specifications before seating. Inspect seating surfaces for burrs or damage that could cause uneven load distribution or premature spring failure.
