Associated Spring Raymond 203-712 Die Spring 3 in Green

Product Description

The ASSOCIATED SPRING RAYMOND 203-712 is a heavy-duty die spring engineered for use in metal stamping, forming, and die tooling applications. Built from chromium alloy steel with a trapezoidal wire cross-section, this spring delivers consistent force and fatigue resistance across repeated cycles. It measures 3 inches in free length with a hole diameter of 40 millimeters and a rod diameter of 20 millimeters. The green color coding indicates load classification per ISO 10243 standards. A maximum deflection of 30 millimeters and a spring rate of 359.74 newtons per millimeter make this a reliable component for medium-to-heavy die work.

This die spring is suited for installation in punch and die sets, press tooling, and mold assemblies found in manufacturing and fabrication environments. It fits into standard die spring pockets sized to accept a 40-millimeter outer diameter. The 3-inch free length makes it a common selection for mid-range stroke applications in progressive, compound, and transfer dies. Installation is typically performed by tool and die makers or maintenance machinists during die build or scheduled tooling maintenance.

Key Features

• Chromium alloy steel construction for high fatigue life under cyclic loading
• Trapezoidal wire shape increases load capacity relative to round wire springs of similar size
• Green color coding per ISO 10243 for quick visual load-class identification
• Maximum deflection load of 1890 newtons at 30 millimeters travel to solid
• Spring rate of 359.74 newtons per millimeter for predictable, linear force output
• Manufactured under ISO 9001:2008 and ISO/TS 16949:2009 certified quality systems

Compatibility

Designed as an OEM-style replacement or direct-fit component for standard die spring pockets requiring a 40-millimeter outer diameter, 20-millimeter rod diameter, and 3-inch free length in the green load classification per ISO 10243.

Installation Notes

Die springs are installed by qualified tool and die makers or industrial maintenance personnel during die assembly or rebuild. Always relieve all press tonnage and lock out the press before removing or replacing die springs. Ensure the spring pocket and guide rod are clean, free of burrs, and within the manufacturer dimensional tolerances before seating the new spring. Do not compress the spring beyond its rated maximum deflection to avoid permanent set or premature failure.
