Gibraltar DCIH25-178 Heavy-duty Die Spring 7 Inch Red

Product Description

The GIBRALTAR DCIH25-178 is a heavy-duty die spring designed for use in stamping dies, molds, and industrial tooling applications where consistent, high-force return pressure is required. Built from chromium alloy steel with a trapezoidal wire profile, this spring delivers a maximum deflection load of 662 pounds (2945.90 N) and a spring rate of 258 pounds per inch. The 7-inch free length compresses to a solid length of approximately 2.56 inches at maximum load, providing 2.56 inches of usable deflection travel. The red color coding indicates heavy-duty load classification, following industry-standard color identification used across NAAMS and ISO 10243 systems. Licensed tool and die makers, machinists, and industrial maintenance technicians are the primary installers.

This die spring is suited for use in progressive dies, injection molds, metal stamping fixtures, and similar high-cycle tooling found in automotive, aerospace, and general manufacturing environments. Its trapezoidal wire cross-section increases coil contact area compared to round wire, supporting higher load capacity within a compact envelope. The 1-inch hole diameter accommodates standard guide posts, and the 0.5-inch rod diameter fits common inner-rod retention configurations used in production tooling.

Key Features

• Heavy-duty load rating with 662 pounds maximum deflection load
• Trapezoidal wire shape for higher load capacity and longer fatigue life compared to round wire springs
• Chromium alloy steel construction for durability under high-cycle conditions
• Red color coding for immediate heavy-duty load class identification per NAAMS and ISO 10243 standards
• Spring rate of 258 pounds per inch for predictable, consistent force output
• Meets NAAMS, ISO 10243, and ISO 9001:2015 registered standards

Compatibility

Designed as an OEM-style replacement or direct-fit die spring for heavy-duty stamping dies, injection molds, and industrial tooling that require a 1-inch hole diameter, 0.5-inch rod diameter, and 7-inch free length heavy-duty spring per NAAMS or ISO 10243 specifications.

Installation Notes

Installation is typically performed by tool and die makers or industrial maintenance technicians during die builds or scheduled tooling maintenance. Always relieve all press or clamp pressure and lock out the machine before removing or installing die springs. Verify that the guide post and rod dimensions match the hole and rod diameter specifications before seating the spring. Do not compress the spring beyond its rated maximum deflection of 2.56 inches to avoid damage or premature failure.
