Associated Spring Raymond 204-612 Die Spring 3 Inch Blue

Product Description

The ASSOCIATED SPRING RAYMOND 204-612 is a heavy-duty die spring engineered for use in stamping dies, press tooling, and industrial mold assemblies. It features a trapezoidal wire shape that delivers a higher spring rate compared to round-wire alternatives, allowing more force output within a compact installation envelope. With a free length of 3 inches and a spring rate of 459.67 N/mm, this blue-coded spring falls in the heavy-load classification range used across standard die spring systems. The body is constructed from chromium alloy steel for consistent fatigue resistance under repeated compression cycles. Toolmakers, die setters, and maintenance technicians working with stamping or injection mold equipment are the primary installers.

This die spring is suited for industrial tooling applications including metal stamping dies, plastic injection molds, and progressive die assemblies. The blue color coding identifies it as a heavy-load spring per ISO 10243 standards, making it straightforward to cross-reference and replace within existing tooling setups. It fits into a 32 mm hole diameter and rides on a 16 mm rod diameter, dimensions common across standardized die sets used in production manufacturing environments.

Key Features

• Trapezoidal wire cross-section for higher load capacity versus round-wire springs of equivalent size
• Blue color coding indicating heavy-load classification per ISO 10243
• 3 inch free length with 28 mm maximum deflection travel to solid load
• Maximum deflection load of 2254 N at full compression
• Chromium alloy steel construction for fatigue resistance in high-cycle tooling applications
• Manufactured under ISO 9001:2008 and ISO/TS 16949:2009 certified quality systems with TUV Rheinland registration

Compatibility

Designed as an ISO 10243-compliant heavy-load die spring for use in standardized die sets requiring a 32 mm hole diameter and 16 mm rod diameter with a 3 inch free length.

Installation Notes

Installation is performed by toolmakers or die maintenance technicians during die build or scheduled tooling maintenance. Before replacing a die spring, fully de-energize and lockout the press to relieve all stored mechanical energy. Confirm the hole and rod diameters of the existing tooling match the spring dimensions before seating. Do not exceed the rated maximum deflection of 28 mm, as over-compression accelerates fatigue failure and can damage surrounding tooling components.
