Associated Spring Raymond 204-212 Die Spring 3 in Blue

Product Description

The ASSOCIATED SPRING RAYMOND 204-212 is a heavy-duty die spring designed for use in stamping dies, press tooling, and industrial machinery applications. Built from chromium alloy steel with a trapezoidal wire cross-section, this spring delivers consistent force and extended fatigue life under high-cycle loading conditions. It features a 3-inch (76 mm) free length, a 12.50 mm hole diameter, and a spring rate of 58.24 N/mm. The blue color coding identifies its load category, allowing toolmakers and maintenance technicians to quickly identify and replace springs during die maintenance. It is installed by tool and die makers, press maintenance technicians, and industrial maintenance professionals.

This die spring is suited for use in metal stamping dies, injection molds, punch and die sets, and general industrial press tooling where controlled force and repeatable deflection are required. It fits into a 12.50 mm hole diameter and accepts a 6.30 mm rod diameter, making it compatible with standard die set configurations. The maximum deflection is 28.90 mm with a corresponding maximum deflection load of 294.80 N. Applications span both production stamping operations and toolroom die repair across a range of industries.

Key Features

• Trapezoidal wire cross-section provides higher load capacity per unit length compared to round wire springs
• Blue color coding identifies load class for fast visual identification during die maintenance
• Chromium alloy steel construction for high fatigue resistance under repeated cycling
• 3-inch (76 mm) free length with 28.90 mm maximum deflection for predictable travel control
• Meets ISO 10243 standard for die springs
• Manufactured under ISO 9001:2008 and ISO/TS 16949:2009 certified quality systems with TUV Rheinland registration

Compatibility

Designed as an OEM-style replacement or toolroom stock die spring for standard 12.50 mm hole diameter die sets requiring a blue-class, 3-inch free length spring per ISO 10243 specifications.

Installation Notes

Die springs are installed by qualified tool and die makers or industrial maintenance technicians. Always de-energize and lock out the press before removing or replacing die springs. Confirm hole diameter and rod diameter clearances match the die set before installation, and never exceed the rated maximum deflection of 28.90 mm to avoid premature failure or damage to tooling.
