Gibraltar DCIH16-38 Heavy-duty Die Spring Red

Product Description

The GIBRALTAR DCIH16-38 is a heavy-duty die spring designed for use in die sets, stamping presses, and tooling fixtures where consistent, high-force return pressure is required. Built from chromium alloy steel with a trapezoidal wire cross-section, it delivers a maximum deflection load of 177.00 pounds and a spring rate of 290 pounds per inch. The red color coding identifies it as a heavy-duty load rating per industry convention. With a 0.625-inch hole diameter and an 11/32-inch rod diameter, this spring seats reliably on standard guide rods used in press tooling applications. Installation is typically handled by tooling engineers, die makers, and maintenance technicians working on metal stamping or forming equipment.

This spring is suited for use in industrial die sets and press tooling where heavy-duty return force and precise dimensional compliance are required. The 1.5-inch free length and 0.610-inch maximum deflection make it appropriate for applications with moderate stroke requirements and high load demands. It meets NAAMS and ISO 10243 standards, making it a direct fit for tooling designed to those specifications. Sold individually, it is a practical replacement or spare component for existing die assemblies.

Key Features

• Heavy-duty load rating with 177.00 lb maximum deflection load
• Trapezoidal wire shape provides higher load capacity versus round wire at equivalent size
• Chromium alloy steel construction for fatigue resistance under cyclic loading
• Red color coding for quick visual identification of duty rating
• Compliant with NAAMS, ISO 10243, and manufactured under ISO 9001:2015 registered quality standards
• Spring rate of 290 pounds per inch for predictable, consistent deflection behavior

Compatibility

Designed as a replacement or service die spring for industrial press tooling and die sets built to NAAMS or ISO 10243 dimensional standards, requiring a 0.625-inch hole diameter and 11/32-inch rod diameter guide pin.

Installation Notes

Installation is typically performed by qualified tooling or maintenance personnel with the press locked out and de-energized per applicable LOTO procedures. Ensure the guide rod diameter does not exceed 11/32 inches and that the die pocket hole is sized to 0.625 inches to allow proper seating without binding. Do not compress the spring beyond its maximum deflection of 0.610 inches, as exceeding this limit can cause permanent set or premature failure. Inspect mating tooling surfaces for burrs or misalignment before assembly.
