Gibraltar DCIL16-89 Die Spring Light-duty Green 3.5 in

Product Description

The GIBRALTAR DCIL16-89 is a light-duty die spring designed for use in stamping dies, molds, and industrial tooling fixtures where consistent, reliable spring force is required. It features a 0.625-inch hole diameter, a 0.344-inch rod diameter, and a free length of 3.5 inches. The spring is wound from chromium alloy steel with a trapezoidal wire cross-section, which delivers higher load capacity per unit of space compared to round-wire springs. A green color code identifies this as a light-duty rating per ISO and NAAMS standards. Maximum deflection load is 109.0 pounds, with a spring rate of 51.0 pounds per inch. Licensed toolmakers, die setters, and precision fabricators are the typical installers.

This die spring is suited for light-duty applications in stamping dies, injection molds, and progressive die tooling in both automotive and general manufacturing environments. The green color coding allows quick visual identification during setup and maintenance, reducing the chance of mismatched spring loads in multi-spring die sets. The 3.5-inch free length and 2.14-inch maximum deflection give the spring meaningful travel for stripper plate and lifter applications. It meets NAAMS and ISO 10243 dimensional standards, making it interchangeable with other compliant components in metric and inch-based tooling systems.

Key Features

• Light-duty rating with 109.0-pound maximum deflection load and 51.0 lb/in spring rate
• Trapezoidal wire cross-section provides higher load density than conventional round-wire springs
• Green color coding per NAAMS and ISO 10243 for rapid visual duty-class identification
• Chromium alloy steel construction for fatigue resistance in cyclic tooling applications
• 2.14-inch maximum deflection with a compressed solid length of 2.14 inches
• Meets NAAMS, ISO 10243, and ISO 9001:2015 registered quality standards

Compatibility

Designed as an OEM-style replacement or drop-in addition for light-duty die spring positions conforming to NAAMS and ISO 10243 standards, with a 0.625-inch hole diameter and 0.344-inch rod diameter mounting envelope.

Installation Notes

Die springs are installed by toolmakers or die setters during die build or maintenance with the press locked out and all stored energy fully relieved. The spring should be seated concentrically over the guide rod with the rod diameter and hole diameter verified against the design spec before closing the die set. Do not compress the spring beyond its rated maximum deflection, as overcompression accelerates fatigue failure. Follow applicable plant safety and OSHA lockout-tagout procedures before any die entry.
