Associated Spring Raymond 203-504 Die Spring 1 in Green

Product Description

The ASSOCIATED SPRING RAYMOND 203-504 is a heavy-duty die spring engineered for use in stamping dies, punch presses, and industrial tooling applications. Manufactured from chromium alloy steel, it features a trapezoidal wire cross-section that delivers higher load capacity in a given space compared to round-wire designs. This spring has a free length of 1 inch (25.00 mm), a hole diameter of 25.00 mm, and a rod diameter of 12.50 mm. It is color-coded green to indicate its load rating within a standardized die spring classification system. Installation and replacement are typically performed by tooling maintenance technicians and die setters working in metal stamping and fabrication environments.

This spring is suited for use in metal stamping dies, injection mold tooling, and precision industrial machinery where consistent spring force and predictable deflection are required. The 203-504 is appropriate for applications demanding a maximum deflection of 10.20 mm and a maximum deflection load of 1020.00 N. The green color designation follows the ISO 10243 standard classification, identifying this unit within the light-to-medium load range for die springs of this size class.

Key Features

• Trapezoidal wire cross-section provides higher load density than comparable round-wire springs
• Chromium alloy steel construction for durability under repeated cyclic loading
• Green color coding for quick visual identification per ISO 10243 classification
• Spring rate of 571.02 N/mm for predictable and consistent force output
• Maximum deflection of 10.20 mm with a travel-to-solid load of 10.20 mm
• Manufactured under ISO 9001:2008 and ISO/TS 16949:2009 certified quality systems

Compatibility

Designed as an OEM-style replacement die spring for stamping dies, punch presses, and industrial tooling setups that accept a 25.00 mm hole diameter and 12.50 mm rod diameter spring with a 1 inch free length per ISO 10243 specifications.

Installation Notes

Die springs should be installed and replaced by qualified tooling technicians or die setters familiar with press tooling maintenance procedures. Always de-energize and lock out the press before performing any spring replacement. Ensure the rod diameter and hole diameter of the tooling match the spring dimensions exactly before installation. Do not compress the spring beyond its rated maximum deflection, as exceeding travel-to-solid limits will shorten service life and may cause tooling damage.
