Associated Spring Raymond 204-204 Die Spring 1 in Blue

Product Description

The ASSOCIATED SPRING RAYMOND 204-204 is a heavy-duty die spring engineered for use in stamping dies, molds, and press tooling applications. Built from chromium alloy steel with a trapezoidal wire cross-section, it delivers a spring rate of 171.30 N/mm and a maximum deflection load of 285.00 N over a maximum deflection of 9.50 mm. The blue color coding identifies its load classification per ISO 10243 standards. With a free length of 1 inch (25.00 mm), a hole diameter of 12.50 mm, and a rod diameter of 6.30 mm, this spring is sized for precision fitment in standard die sets. Installation is handled by toolmakers, die setters, and maintenance technicians working in metal stamping and injection molding environments.

This die spring is suited for use in stamping dies, progressive dies, forming tools, and mold assemblies where consistent, repeatable spring force is required. The trapezoidal wire geometry provides higher load capacity relative to round-wire springs of the same envelope size, making it appropriate for high-cycle industrial press applications. The blue designation under ISO 10243 indicates a medium load classification. Typical users include tool-and-die shops, press room maintenance crews, and OEM tooling manufacturers maintaining or building standard die sets.

Key Features

• Chromium alloy steel construction for high fatigue resistance in cyclic loading applications
• Trapezoidal wire cross-section delivers elevated load capacity within a compact envelope
• Blue color coding per ISO 10243 medium load classification for quick visual identification
• Free length of 1 inch (25.00 mm) with 9.50 mm travel to solid load
• Spring rate of 171.30 N/mm with a maximum deflection load of 285.00 N
• Manufactured under ISO 9001:2008 and ISO/TS 16949:2009 certified quality systems, TUV Rheinland registered

Compatibility

Designed as an OEM-style replacement or direct-fit die spring for standard tooling applications requiring a 12.50 mm hole diameter, 6.30 mm rod diameter, and 25.00 mm free length in the ISO 10243 medium-load blue classification.

Installation Notes

Die springs are installed and serviced by toolmakers or press room maintenance personnel. Before replacing or inspecting die springs, confirm the press is fully de-energized, blocked, and locked out per applicable safety procedures. Verify the spring free length, hole diameter, and rod diameter match the die set pocket dimensions before seating the spring. Do not exceed the rated maximum deflection of 9.50 mm during operation, as compressing beyond the travel-to-solid specification will reduce service life and may damage tooling.
