Associated Spring Raymond 205-812 Die Spring 3 in Red

Product Description

The ASSOCIATED SPRING RAYMOND 205-812 is a heavy-duty die spring designed for use in stamping dies, punch presses, and industrial tooling applications. It is manufactured from chromium alloy steel and features a trapezoidal wire cross-section, which provides a higher load capacity and longer fatigue life compared to round-wire springs. The red color designation indicates a heavy load classification per ISO 10243 standards. With a free length of 3 inches and a rod diameter of 25 mm, this spring is suited for demanding cyclic compression environments found in metal fabrication and tooling operations. Installation and replacement are typically performed by toolroom machinists or maintenance technicians.

This die spring is used in stamping dies, injection mold tooling, jigs, fixtures, and other precision industrial equipment requiring consistent, repeatable spring force. The red series heavy-load classification makes it appropriate for applications where high deflection resistance and reliable return force are required within a compact envelope. It fits a 50 mm hole diameter and accepts a 25 mm rod diameter, which are standard dimensions across a wide range of industrial tooling setups.

Key Features

• Trapezoidal wire cross-section increases load capacity and fatigue resistance versus round-wire die springs
• Red color coding identifies heavy-load classification per ISO 10243
• Chromium alloy steel construction for durability under high-cycle compression
• 3 inches free length with 23 mm maximum deflection travel to solid
• Maximum deflection load of 7797 newtons at full compression
• Manufactured under ISO 9001:2008, ISO/TS 16949:2009, and TUV Rheinland registered quality systems

Compatibility

Designed as a standard replacement or new-installation die spring conforming to ISO 10243 specifications, suitable for tooling applications that require a 50 mm hole diameter and 25 mm rod diameter heavy-load spring.

Installation Notes

Die spring replacement and installation should be performed by qualified toolroom or maintenance personnel with the press or tooling equipment fully de-energized and locked out per applicable OSHA lockout/tagout procedures. Ensure the rod and hole dimensions of the tooling match the spring specifications before installation. Do not exceed the maximum deflection rating, as compressing beyond travel-to-solid will permanently damage the spring and may create a safety hazard.
