Associated Spring Raymond 204-710 Die Spring 2.5 in Blue

Product Description

The ASSOCIATED SPRING RAYMOND 204-710 is a blue-coded die spring engineered for high-load tooling and stamping die applications. It features a trapezoidal wire profile, which maximizes load capacity within a compact envelope compared to round-wire designs. The spring has a free length of 2.5 inches (64 mm), a rod diameter of 20 mm, and a hole diameter of 40 mm. Manufactured from chromium alloy steel, it delivers consistent spring rates and fatigue resistance under repetitive press cycles. Die maintenance technicians and toolroom machinists are the primary installers.

This die spring is suited for use in progressive dies, compound dies, and other metal stamping tooling where controlled stripping or pressure force is required. The blue color designation indicates a medium-heavy load range per ISO 10243 classification. It is commonly installed in both standard and custom die sets across light industrial and heavy manufacturing environments. Typical applications include stripping, clamping, and workpiece ejection within press tool assemblies.

Key Features

• Trapezoidal wire cross-section increases load capacity versus standard round-wire die springs
• Blue color code indicates medium-heavy load rating per ISO 10243
• Maximum deflection load of 3360 newtons at full travel to solid
• Maximum deflection of 24 mm with a spring rate of approximately 799.42 N/mm
• Chromium alloy steel construction for fatigue resistance under high-cycle press operation
• Manufactured under ISO 9001:2008 and ISO/TS 16949:2009 certified quality systems with TUV Rheinland registration

Compatibility

Designed as an OEM-style replacement or direct-fit die spring for tooling assemblies requiring a 40 mm hole diameter, 20 mm rod diameter, and 64 mm free length per ISO 10243 medium-heavy load specifications.

Installation Notes

Die springs are installed by toolroom machinists or die maintenance technicians during die build or routine press maintenance. Power down and lock out the press before removing or installing any die components. Springs should be seated squarely on the rod and within the pocket bore without side loading. Never compress a die spring beyond its rated maximum deflection, as exceeding travel-to-solid limits will shorten spring life and may cause failure during press operation.
