Associated Spring Raymond 205-210 Die Spring Red

Product Description

The ASSOCIATED SPRING RAYMOND 205-210 is a heavy-duty die spring engineered for use in stamping dies, press tooling, and industrial mold applications. It features a trapezoidal wire cross-section, which delivers a higher load-bearing capacity per unit of length compared to round-wire springs. The spring has a free length of 2.5 inches (64 mm), a rod diameter of 6.30 mm, a hole diameter of 12.50 mm, and a spring rate of 85.65 N/mm. The red color coding indicates a medium-load classification per ISO 10243 standards. Manufactured from chromium alloy steel for durability under cyclic compression loads.

This die spring is suited for use in progressive dies, transfer tooling, injection molds, and punch-and-die assemblies in both light and heavy manufacturing environments. It is installed by tool and die makers, mold technicians, and maintenance machinists during die build or die repair operations. The compact dimensions make it appropriate for installations where space inside the die set is limited while consistent return force is still required.

Key Features

• Trapezoidal wire shape provides higher load density compared to round-wire die springs
• Red color coding indicates medium-load classification per ISO 10243
• Chromium alloy steel construction for resistance to fatigue under repeated cycling
• 2.5 inch free length with 19.20 mm maximum deflection travel to solid
• Maximum deflection load of 288.00 N at full compression
• Meets ISO 9001:2008, ISO/TS 16949:2009, and TUV Rheinland quality standards

Compatibility

Designed as an OEM-style replacement or direct-fit die spring for stamping dies and press tooling applications requiring a 12.50 mm hole diameter, 6.30 mm rod diameter, and 64 mm free length per ISO 10243 medium-load specifications.

Installation Notes

Installation is performed by qualified tool and die makers or mold technicians. Ensure the press or machine is fully de-energized and all stored energy is released before removing or replacing die springs. The spring must be seated squarely on the rod or in the pocket bore to prevent lateral loading and premature fatigue failure. Inspect mating bores and rods for wear or damage before installing a replacement spring.
