Gibraltar DCIM25-25 Die Spring 1 in Blue Medium-duty

Product Description

The GIBRALTAR DCIM25-25 is a medium-duty die spring designed for use in tooling, stamping dies, and mechanical press applications. It features a trapezoidal wire shape wound from chromium alloy steel, giving it high load capacity and consistent performance across repeated compression cycles. The spring has a 1-inch hole diameter, a 0.5-inch rod diameter, and a 1-inch free length. At maximum deflection of 0.39 inches, it delivers a load of 385 pounds. With a spring rate of 979 pounds per inch, it provides predictable resistance throughout its travel range. This part is sold individually and is suited for use by tool-and-die technicians, maintenance machinists, and industrial equipment technicians.

This die spring is used in punch-and-die assemblies, injection mold tooling, metal stamping presses, and general industrial machinery where controlled return force is required. The blue color coding indicates medium-duty classification, consistent with NAAMS and ISO 10243 standards for die spring duty ratings. It is appropriate for both OEM tooling builds and field replacement in existing die sets where a medium-duty blue spring of this size is specified.

Key Features

• Trapezoidal wire cross-section for higher load capacity compared to round-wire springs of equivalent size
• Chromium alloy steel construction for durability under repeated compression cycles
• 385-pound maximum deflection load at 0.39 inches of travel
• Spring rate of 979 pounds per inch for predictable, linear force output
• Blue color coding identifies medium-duty classification per NAAMS and ISO 10243 standards
• Meets ISO 9001:2015 registered manufacturing standards

Compatibility

Designed as a medium-duty die spring replacement for tooling and stamping die assemblies requiring a 1-inch hole diameter, 0.5-inch rod diameter, and 1-inch free length per NAAMS and ISO 10243 specifications.

Installation Notes

Die spring installation and replacement should be performed by qualified tool-and-die technicians or maintenance personnel with the press or tooling assembly fully de-energized and relieved of hydraulic or mechanical pressure before service. Inspect the mating rod and hole bore for wear or misalignment prior to installation, as side-loading will reduce spring service life. Do not compress the spring beyond its rated maximum deflection of 0.39 inches during operation.
