Gibraltar DCIH25-25 Heavy-duty Die Spring Red

Product Description

The GIBRALTAR DCIH25-25 is a heavy-duty die spring engineered for use in stamping dies, molds, and industrial tooling applications. Built from chromium alloy steel with a trapezoidal wire cross-section, this spring delivers consistent force and controlled compression in demanding press environments. It features a 1-inch hole diameter, a 1/2-inch rod diameter, and a 1-inch free length. The maximum deflection load is 635 pounds, with a spring rate of 2,121 pounds per inch. The red color coding identifies it as a heavy-duty rated spring per industry convention, making identification fast during setup and maintenance. Licensed HVAC, plumbing, and industrial maintenance technicians working with pneumatic or hydraulic tooling assemblies regularly specify springs of this type.

This die spring is suited for use in punch and die assemblies, injection mold tooling, and similar high-cycle industrial equipment. It fits standard rod-guided spring pockets with a 1-inch bore. The compact 1-inch free length makes it well-suited for tight tooling envelopes where space is limited. It meets NAAMS and ISO 10243 standards, making it appropriate for automotive tooling and other precision manufacturing environments where interchangeability and dimensional compliance are required.

Key Features

• Heavy-duty duty rating with a maximum deflection load of 635 pounds (2,825.75 N)
• Trapezoidal wire cross-section for higher load capacity in a compact envelope
• Chromium alloy steel construction for fatigue resistance under high-cycle conditions
• Red color coding per standard heavy-duty spring classification
• Meets NAAMS, ISO 10243, and ISO 9001:2015 standards
• Maximum deflection of 0.3 inches (7.62 mm) with a compressed solid length of 0.3 inches

Compatibility

Designed as a standard-dimension replacement or new-build component for rod-guided die spring pockets requiring a 1-inch hole diameter and 1/2-inch rod diameter. Dimensional compliance with ISO 10243 and NAAMS standards supports direct interchangeability with other conforming springs in those systems.

Installation Notes

Installation is typically performed by toolroom technicians or industrial maintenance personnel. Confirm that the mating die pocket bore and rod diameter match the spring specifications before installation. Relieve all press pressure and lock out the press or tooling system before removing or installing die springs. Do not compress the spring beyond its rated maximum deflection, as overtravel can cause premature fatigue failure or sudden fracture.
