Associated Spring Raymond 106-404 Die Spring Extra Heavy-duty

Product Description

The ASSOCIATED SPRING RAYMOND 106-404 is an extra heavy-duty die spring designed for high-load tooling and stamping applications. It features a trapezoidal wire shape and is manufactured from chromium alloy steel for durability under repeated compression cycles. The spring measures 3/4 inches in hole diameter, 3/8 inches in rod diameter, and 1 inch in free length. It carries a maximum deflection load of 350 pounds and a maximum deflection of 0.25 inches, with a spring rate of 1,400 pounds per inch. The green color coding indicates extra heavy-duty duty rating per standard die spring classifications. Tooling engineers, die setters, and maintenance technicians working with stamping presses and progressive dies are the primary installers.

This die spring is suited for use in metal stamping dies, punch press tooling, plastic injection molds, and other industrial tooling applications requiring a compact, high-load compression spring. The 1-inch free length makes it appropriate for tight die clearances where space is limited. Its extra heavy-duty rating supports applications involving high cycle counts and substantial compressive forces, common in production stamping and fabrication environments.

Key Features

• Extra heavy-duty duty rating with green color coding per standard die spring classification
• Trapezoidal wire shape for higher load capacity relative to round-wire springs of similar dimensions
• Chromium alloy steel construction for fatigue resistance under high-cycle conditions
• 350-pound maximum deflection load with a spring rate of 1,400 pounds per inch
• Compact 1-inch free length suitable for confined tooling spaces
• Manufactured under ISO 9001:2008, ISO/TS 16949:2009, and TUV Rheinland quality standards

Compatibility

Designed as a standard-dimension die spring for use in metal stamping dies, punch tooling, and industrial mold assemblies requiring a 3/4-inch hole diameter and 3/8-inch rod diameter with a 1-inch free length.

Installation Notes

Die springs should be installed by qualified toolroom technicians or die setters familiar with press tooling assembly. Always de-energize and lock out the press before accessing the die set. Springs should be seated squarely on the rod and within the pocket to prevent lateral loading. Never compress the spring beyond its rated maximum deflection of 0.25 inches, as over-compression reduces service life and can cause premature failure.
