Associated Spring Raymond 203-718 Die Spring 4.5 in Green

Product Description

The ASSOCIATED SPRING RAYMOND 203-718 is a heavy-duty die spring designed for use in metal stamping dies, press tooling, and industrial mold assemblies. Built from chromium alloy steel with a trapezoidal wire cross-section, this spring delivers higher load capacity and longer fatigue life compared to standard round-wire springs. The green color coding identifies it within the ISO 10243 classification system, indicating a specific load range. Free length is 4.5 inches (115 mm), with a rod diameter of 20 mm and a hole diameter of 40 mm. Licensed HVAC, tool-and-die, and industrial maintenance professionals install this spring as a direct replacement or original fitment in die sets requiring consistent, repeatable spring force.

This die spring is suited for press and die applications in manufacturing environments where dimensional precision and load consistency are critical. The trapezoidal wire geometry maximizes the number of active coils within a given space, improving load-bearing performance over the full deflection range. With a maximum deflection of 46 mm and a travel-to-solid load of 46 mm, this spring is appropriate for moderate-to-high load stamping and forming operations. It is used in both new die builds and die maintenance programs where worn or fatigued springs require replacement to maintain press accuracy and part quality.

Key Features

• Trapezoidal wire cross-section for increased load capacity versus round-wire die springs
• Green color coding per ISO 10243 for quick load-range identification in the field
• Chromium alloy steel construction for durability under repeated cycling
• 4.5 inch (115 mm) free length with 46 mm maximum deflection travel
• Manufactured under ISO 9001:2008 and ISO/TS 16949:2009 quality management systems
• TUV Rheinland registered and ANAB accredited production

Compatibility

Designed as an OEM-style replacement die spring for press and stamping die assemblies requiring a 40 mm hole diameter, 20 mm rod diameter, and 4.5 inch free length conforming to ISO 10243 specifications.

Installation Notes

Die springs are installed and replaced by tool-and-die makers or industrial maintenance technicians. Always relieve all press tonnage and lock out the press ram before removing or installing die springs. Inspect the die pocket and guide rod for wear or surface damage that could cause uneven loading or premature spring failure. Do not exceed the rated maximum deflection of 46 mm, as operating beyond this value reduces fatigue life significantly.
