Associated Spring Raymond 203-507 Die Spring 1-3/4 in

Product Description

The ASSOCIATED SPRING RAYMOND 203-507 is a heavy-duty die spring designed for use in stamping dies, molds, and industrial tooling applications. It features a trapezoidal wire shape wound from chromium alloy steel, which delivers higher load capacity in a compact envelope compared to standard round-wire springs. With a free length of 1.75 inches (44 mm), a rod diameter of 12.50 mm, and a hole diameter of 25.00 mm, this spring fits standard die sets where space and load precision are critical. It is color-coded green to indicate its load rating class for quick field identification during setup and maintenance.

This die spring is suited for use in press tooling, injection mold assemblies, stripper plates, and similar industrial die components. It is commonly installed by tool and die makers, mold technicians, and maintenance machinists in manufacturing environments. The green color coding is consistent with standard die spring load classification systems, making it straightforward to source and replace in the field without confusion.

Key Features

• Trapezoidal wire cross-section provides higher load density than round-wire alternatives
• Chromium alloy steel construction for durability under repeated cycling
• Green color coding identifies load class at a glance during die maintenance
• Free length of 1.75 inches (44 mm) with 18 mm maximum deflection
• Spring rate of 302.07 N/mm for predictable, consistent force output
• Manufactured to ISO 10243 standards with ISO 9001:2008 and ISO/TS 16949:2009 certifications

Compatibility

Designed as an OEM-style replacement die spring for standard industrial stamping dies, stripper plate assemblies, and mold tooling that accept a 25 mm hole diameter and 12.50 mm rod diameter green-class die spring per ISO 10243 specifications.

Installation Notes

Installation is typically performed by tool and die makers or maintenance machinists with the press or mold fully de-energized and at zero pressure. Verify that the mating hole diameter and rod diameter match the spring dimensions before installation. Do not exceed the rated maximum deflection of 18 mm, as over-compression will reduce service life and can cause premature failure. Inspect mating surfaces for burrs or contamination before seating the spring.
