Gibraltar DCIL25-305 Die Spring 12 in Light-duty Green

Product Description

The GIBRALTAR DCIL25-305 is a light-duty die spring engineered for use in stamping dies, molds, and progressive tooling applications. It features a 1-inch hole diameter, 0.5-inch rod diameter, and a 12-inch free length, making it suitable for setups that require a longer spring travel. Constructed from chromium alloy steel with a trapezoidal wire cross-section, this spring delivers consistent force characteristics across its deflection range. A maximum deflection load of 247 pounds and a spring rate of 39 pounds per inch define its performance envelope. Licensed tool-and-die makers, mold makers, and industrial maintenance technicians are the primary installers.

This die spring is suited for light-duty press tool and mold applications in both production and maintenance environments. Its green color coding follows industry convention for light-duty load classification, making it easy to identify at a glance during tooling changes or maintenance cycles. The 12-inch free length accommodates applications requiring extended travel before the spring reaches a compressed or solid state. With a compressed length at maximum load of 6.4 inches and a maximum deflection of 6.4 inches, it provides substantial working travel for tooling that demands consistent return force over long strokes.

Key Features

• Light-duty load rating with a maximum deflection load of 247 pounds (1099.15 N)
• Trapezoidal wire cross-section for improved load distribution and fatigue resistance
• Chromium alloy steel construction for durability under cyclic compression
• Green color coding identifies light-duty classification per industry standards
• 12-inch free length provides extended working travel for demanding tooling setups
• Meets NAAMS, ISO 10243, and ISO 9001:2015 standards

Compatibility

Designed as an OEM-style replacement die spring for light-duty stamping dies, molds, and progressive tooling assemblies requiring a 1-inch hole diameter and 0.5-inch rod diameter.

Installation Notes

Die spring replacement and installation should be performed by qualified tool-and-die makers or industrial maintenance technicians with the press or mold locked out and de-energized per LOTO procedures. Verify hole and rod diameter clearances before installation to prevent binding or misalignment under load. Never compress a die spring beyond its rated maximum deflection, as exceeding the solid height can cause permanent set or spring failure. Replace springs in matched sets where tooling design requires balanced load distribution.
