Associated Spring Raymond 203-610 Die Spring 2.5 in Green

Product Description

The ASSOCIATED SPRING RAYMOND 203-610 is a heavy-duty die spring designed for use in stamping dies, punch presses, and injection molds. It features a trapezoidal wire cross-section that delivers higher load capacity per unit volume compared to round-wire springs of equivalent size. With a free length of 2.5 inches and a rod diameter of 16.00 mm, this green-coded spring falls in the heavy-load classification per ISO 10243. It is manufactured from chromium alloy steel for fatigue resistance and consistent spring rate across high-cycle tooling environments. Toolmakers, die setters, and maintenance technicians working in metal fabrication and plastics processing are the primary installers.

This die spring is suited for precision tooling applications in both production and prototype stamping dies, as well as injection mold tooling. The green color coding indicates a heavy-load rating under the ISO 10243 standard, making it appropriate where higher forces are required in a compact footprint. It is used in both OEM die build and die repair and maintenance contexts across light manufacturing and heavy industrial settings.

Key Features

• Trapezoidal wire shape provides higher load density than round-wire equivalents
• Green color code denotes heavy-load classification per ISO 10243
• 2.5 inch free length with 25.00 mm maximum deflection travel to solid
• Maximum deflection load of 1325.00 N with a spring rate of 302.64 N/mm
• Chromium alloy steel construction for high-cycle fatigue resistance
• Manufactured under ISO 9001:2008 and ISO/TS 16949:2009 certified quality systems

Compatibility

Designed as an OEM-style replacement or direct-fit die spring for stamping dies and injection molds requiring a heavy-load spring with a 32.00 mm hole diameter, 16.00 mm rod diameter, and 2.5 inch free length conforming to ISO 10243 dimensional standards.

Installation Notes

Die springs of this type are installed and replaced by toolmakers or die maintenance technicians. Always de-energize and lock out all press or mold equipment before removing or installing die springs, following applicable machine safety lockout/tagout procedures. Verify the bore diameter and rod diameter clearances against tooling drawings before installation to ensure proper fit and avoid side loading. Do not compress this spring beyond its rated maximum deflection to prevent permanent set or premature failure.
