Associated Spring Raymond 204-316 Die Spring 4 in Blue

Product Description

The ASSOCIATED SPRING RAYMOND 204-316 is a medium-duty die spring designed for use in metal stamping dies, punch presses, and similar tooling applications. Built from chromium alloy steel with a trapezoidal wire profile, it delivers consistent load performance across its compression range. The spring has a free length of 4 inches (102 mm), a rod diameter of 8 mm, and a hole diameter of 16 mm. Maximum deflection load reaches 117.75 pounds (523.80 N) at full compression travel of 38.80 mm. The blue color coding identifies this as a medium-duty spring per ISO 10243 classification. Toolmakers, die setters, and maintenance technicians are the primary installers.

This die spring is used in industrial tooling where controlled spring force and repeatable deflection are required. Typical applications include die cushions, pressure pads, stripper plates, and component ejection mechanisms in stamping and forming dies. The trapezoidal wire shape maximizes material cross-section within the coil geometry, supporting consistent load deflection characteristics over the working life of the spring. It is suited for medium-duty cycles where the blue-rated load range is appropriate for the tooling design.

Key Features

• Medium-duty load rating per ISO 10243 standard, color-coded blue for quick identification
• Trapezoidal wire cross-section for high load capacity relative to coil size
• Chromium alloy steel construction for durability in cyclic compression applications
• 4 inches (102 mm) free length with 38.80 mm maximum deflection travel
• Maximum deflection load of 117.75 pounds (523.80 N)
• Compatible with 8 mm guide rods and 16 mm die holes

Compatibility

Designed for use with 8 mm guide rods and 16 mm hole diameters in standard die tooling per ISO 10243 specifications for medium-duty die springs.

Installation Notes

Die springs are installed and replaced by toolmakers or qualified die maintenance personnel. Always de-energize and lock out the press before performing any die maintenance or spring replacement. Ensure the guide rod and hole diameters match the spring specifications before installation. Do not exceed the maximum deflection travel of 38.80 mm, as compressing the spring to solid will reduce service life and may cause tooling damage.
