Associated Spring Raymond 203-404 Die Spring 1 in Green

Product Description

The ASSOCIATED SPRING RAYMOND 203-404 is a heavy-duty die spring engineered for use in metal stamping, press tooling, and industrial die sets. Built from chromium alloy steel with a trapezoidal wire cross-section, this spring delivers a higher load capacity in a compact footprint compared to standard round-wire springs of the same size. The green color coding indicates a heavy-load classification under ISO 10243. With a free length of 1 inch (25 millimeters), a rod diameter of 10 millimeters, and a maximum deflection load of 569.20 newtons, it is suited for applications where space is limited but force requirements are significant. Tool and die makers, press technicians, and maintenance machinists are the primary installers.

This die spring is intended for installation in metal stamping dies, injection mold assemblies, jigs, fixtures, and industrial press tooling where controlled compression forces are required. The 20 millimeter hole diameter and 10 millimeter rod diameter make it compatible with standard die set pockets following ISO 10243 dimensional guidelines. It fits both OEM die builds and aftermarket tooling repair across a range of light to heavy industrial manufacturing environments. Its compact 1 inch free length suits applications with tight shut heights or shallow spring pockets.

Key Features

• Trapezoidal wire cross-section provides higher load capacity versus standard round-wire die springs of equal size
• Green color code designates heavy-load classification per ISO 10243
• Chromium alloy steel construction offers durability under repeated high-cycle compression
• 1 inch (25 mm) free length suits shallow die pockets and tight shut-height tooling designs
• Maximum deflection load of 569.20 newtons with 10.20 millimeters travel to solid
• Manufactured under ISO 9001:2008, ISO/TS 16949:2009, and TUV Rheinland registration

Compatibility

Designed as an OEM-style replacement or direct-fit component for industrial die sets and press tooling conforming to ISO 10243 standards with a 20 millimeter hole diameter and 10 millimeter rod diameter.

Installation Notes

Installation is performed by tool and die makers or press maintenance technicians. The press or die set must be fully de-energized and at zero pressure before spring replacement. Ensure the spring pocket depth and rod clearance match the free length and rod diameter before seating the spring. Do not exceed the rated maximum deflection of 10.20 millimeters, as compressing a die spring to solid will reduce service life and can cause premature failure.
