Gibraltar DCIM40-64 Die Spring 1-1/2 in Medium-duty Blue

Product Description

The GIBRALTAR DCIM40-64 is a medium-duty die spring designed for use in stamping dies, molds, jigs, and industrial tooling applications. It features a 1.5-inch hole diameter, a 0.75-inch rod diameter, and a free length of 2.5 inches. Wound from chromium alloy steel with a trapezoidal wire shape, this spring delivers a maximum deflection load of 749 pounds and a maximum deflection of 1.02 inches. The blue color coding identifies its medium-duty rating at a glance, making selection and inventory management straightforward on the shop floor. Licensed tool and die technicians and industrial maintenance professionals are the primary installers.

This die spring is suited for use in hydraulic press tooling, progressive die sets, and injection mold assemblies where consistent, repeatable force is required across production cycles. Its chromium alloy steel construction handles the cyclic compression loads common in high-volume stamping and molding operations. The medium-duty classification positions it between light and heavy-duty springs for applications that require moderate resistance without the bulk of a heavy-duty unit. It ships as a single piece and is ordered individually.

Key Features

• Medium-duty rating with a maximum deflection load of 749 pounds
• Trapezoidal wire cross-section for higher load capacity relative to round-wire springs of the same size
• Chromium alloy steel construction for fatigue resistance under cyclic loading
• Blue color coding per ISO 10243 medium-duty designation for quick visual identification
• Compliant with NAAMS and ISO 10243 international die spring standards
• Spring rate of 735 pounds per inch for predictable, linear force delivery

Compatibility

Designed as a standard replacement or new-build die spring for tooling applications requiring a 1.5-inch hole diameter, 0.75-inch rod diameter, and 2.5-inch free length per NAAMS and ISO 10243 dimensional standards.

Installation Notes

Die spring installation and replacement should be performed by qualified tool and die technicians with the press or tooling machine fully de-energized, de-pressurized, and locked out per applicable OSHA lockout-tagout procedures. Verify that the mating bore and rod dimensions match the spring specifications before installation. Do not compress the spring beyond its rated maximum deflection of 1.02 inches, as exceeding travel limits will reduce service life and can cause premature failure. Inspect the spring seat and bore for wear or damage before installing a replacement unit.
