Associated Spring Raymond 203-307 Die Spring 1-3/4 in

Product Description

The ASSOCIATED SPRING RAYMOND 203-307 is a heavy-duty die spring designed for use in stamping dies, molds, and tooling fixtures. Built from chromium alloy steel with a trapezoidal wire cross-section, this spring delivers consistent force throughout its compression cycle. It has a free length of 1.75 inches (44 mm), a rod diameter of 8 mm, and a hole diameter of 16 mm. The green color coding indicates its load rating within the standard die spring classification system. Licensed toolmakers, die setters, and precision machine technicians are the primary installers of this component in production and manufacturing environments.

This die spring is suited for use in press tooling, injection molds, stamping dies, and industrial fixtures where controlled spring force and repeatable deflection are required. It fits applications calling for a green-series die spring with an 8 mm rod diameter and 16 mm hole diameter. With a maximum deflection of 18 mm and a maximum deflection load of 307.80 N, it is appropriate for medium-duty industrial tooling applications in both short-run and high-volume production settings.

Key Features

• Trapezoidal wire shape provides higher load capacity and longer fatigue life compared to round-wire springs
• Chromium alloy steel construction for durability under repeated compression cycles
• Green color coding identifies load class for fast visual identification during die setup
• Free length of 1.75 inches (44 mm) with maximum deflection of 18 mm (18 mm travel to solid load)
• Spring rate of 97.64 N/mm for predictable, linear force delivery
• Manufactured to ISO 10243 standard for dimensional and performance consistency

Compatibility

Designed as an OEM-style replacement or direct-fit die spring for tooling and fixture applications requiring a green-series spring with an 8 mm rod diameter, 16 mm hole diameter, and 1.75-inch free length per ISO 10243.

Installation Notes

Die springs are installed by qualified toolmakers or die setters during die assembly or maintenance. Always relieve all press pressure and lock out the press before removing or replacing die springs. Inspect the rod and hole bore dimensions to confirm fit before installation. Never compress a die spring beyond its rated maximum deflection, as over-compression can cause premature failure or damage to tooling components.
