Associated Spring Raymond 204-310 Die Spring 2.5 in Blue

Product Description

The ASSOCIATED SPRING RAYMOND 204-310 is a heavy-duty die spring designed for use in stamping dies, molds, and industrial tooling applications. It features a trapezoidal wire shape that delivers higher load capacity per unit length compared to round-wire springs of equivalent size. The spring has a free length of 2.5 inches (64 mm), a rod diameter of 8 mm, and a hole diameter of 16 mm. Manufactured from chromium alloy steel, it provides reliable fatigue resistance under repeated compression cycles. The blue color coding identifies the load class per ISO 10243 standards. Licensed fabricators and toolroom machinists are the typical installers of this component.

This die spring is suited for use in hydraulic and mechanical presses, injection molds, stamping dies, jigs, and fixtures where precise, repeatable spring force is required. It is appropriate for both light production tooling and high-cycle industrial die sets. The compact 2.5-inch free length makes it well suited for applications with limited cavity depth. The spring rate of 117.06 N/mm and a maximum deflection of 24.30 mm allow predictable performance across its compression range.

Key Features

• Trapezoidal wire profile provides higher load density than equivalent round-wire die springs
• Blue color code identifies load class per ISO 10243 specification
• Chromium alloy steel construction for fatigue resistance in high-cycle applications
• Maximum deflection load of 498.20 N at full 24.30 mm travel to solid
• Manufactured under ISO 9001:2008 and ISO/TS 16949:2009 certified quality systems
• TUV Rheinland registered and ANAB accredited production standards

Compatibility

Designed as an ISO 10243 standard die spring replacement suitable for stamping dies, injection molds, and industrial tooling that accept a 16 mm hole diameter and 8 mm rod diameter with a 2.5-inch free length.

Installation Notes

Die springs should be installed by qualified toolroom technicians or die maintenance personnel. Always de-energize and lock out the press or machine before servicing any tooling components. Inspect the rod and bore dimensions for proper fit before installation to prevent side loading, which can reduce spring service life. Do not compress the spring beyond the rated travel to solid in normal operation.
