Associated Spring Raymond 104-618 Die Spring Red

Product Description

The ASSOCIATED SPRING RAYMOND 104-618 is a heavy-duty die spring designed for use in metal stamping, die sets, and press tooling applications. Built from chromium alloy steel with a trapezoidal wire profile, it delivers a spring rate of 329.00 lb per inch and a maximum deflection load of 532.8 lb. The 1-1/4 inch hole diameter and 5/8 inch rod diameter provide precise fit within standard die components. At 4-1/2 inches in free length, it offers 1.67 inches of maximum deflection. This spring is color-coded red to indicate its load category, making identification straightforward during setup and maintenance.

This die spring is suited for industrial tooling environments where consistent, repeatable force is required under cyclic compression loads. Typical applications include punch press dies, injection mold tooling, jigs, fixtures, and automated stamping equipment. The chromium alloy steel construction and trapezoidal wire cross-section give it greater load capacity and fatigue resistance compared to standard round-wire springs of the same envelope size. It is installed and serviced by tool and die makers, maintenance technicians, and precision metalworking professionals.

Key Features

• Chromium alloy steel construction for high fatigue resistance under repeated cycling
• Trapezoidal wire shape increases load capacity within a compact envelope
• Color-coded red for quick load-category identification
• Spring rate of 329.00 lb per inch with a maximum deflection load of 532.8 lb
• Maximum deflection of 1.67 inches provides controlled, predictable stroke
• Manufactured under ISO 9001:2008, ISO/TS 16949:2009, and TUV Rheinland quality standards

Compatibility

Designed as a standard-profile die spring for use in tooling applications requiring a 1-1/4 inch hole diameter and 5/8 inch rod diameter with a 4-1/2 inch free length. Verify existing tooling envelope dimensions before installation.

Installation Notes

Die springs should be installed by qualified tool and die technicians familiar with press and die set maintenance. Relieve all press pressure and lock out energy sources before accessing die components. Do not compress this spring beyond its rated maximum deflection of 1.67 inches, as over-compression accelerates fatigue failure. Inspect the spring seating surfaces for burrs or misalignment that could cause uneven load distribution during operation.
