Associated Spring Raymond 203-732 Die Spring 8 in Green

Product Description

The ASSOCIATED SPRING RAYMOND 203-732 is a heavy-duty die spring engineered for use in metal stamping, forming, and press tooling applications. With a free length of 8 inches (203 mm), a hole diameter of 40 mm, and a rod diameter of 20 mm, this spring is sized for mid-range die assemblies requiring consistent, reliable compression force. The green color coding identifies it as a heavy-load rating within the standard die spring classification system. It is made from chromium alloy steel and features a trapezoidal wire cross-section, which provides a higher load capacity relative to round-wire springs of comparable dimensions. Installation is typically performed by toolmakers, die setters, and maintenance technicians in manufacturing and fabrication environments.

This die spring is suited for use in punch and die sets, stripper plates, and pressure pads in both production stamping dies and prototype tooling. The 81 mm maximum deflection (travel to solid) and a spring rate of 129.62 N/mm make it well-matched for applications requiring controlled, repeatable force over a defined stroke. It fits installations where a 40 mm bore and 20 mm rod are specified, consistent with ISO 10243 dimensional standards commonly used in North American and European die manufacturing.

Key Features

• Green color code indicates heavy-load die spring classification
• Trapezoidal wire shape delivers higher load density compared to round-wire designs
• Chromium alloy steel construction for durability under repeated compression cycling
• 81 mm maximum deflection with a maximum deflection load of 1838.70 N
• Conforms to ISO 10243 dimensional standards
• Manufactured under ISO 9001:2008 and ISO/TS 16949:2009 certified quality systems, TUV Rheinland registered

Compatibility

Designed as an ISO 10243-compliant replacement or direct-fit die spring for tooling applications specifying a 40 mm hole diameter, 20 mm rod diameter, and 8 inch (203 mm) free length in the heavy-load green category.

Installation Notes

Die springs of this type are installed by qualified toolmakers or die maintenance technicians. Always ensure the press or die is fully de-energized and in the locked-out, blocked position before removing or installing springs. Verify that the bore and rod dimensions of the die set match the 40 mm hole diameter and 20 mm rod diameter of this spring before installation. Do not exceed the maximum deflection of 81 mm, as operating beyond travel-to-solid load will reduce service life and may cause spring failure.
