Associated Spring Raymond 104-720 Die Spring Red Medium Heavy-duty

Product Description

The ASSOCIATED SPRING RAYMOND 104-720 is a medium heavy-duty die spring designed for use in stamping dies, punch presses, and industrial tooling applications. It features a 1.5-inch hole diameter, a 0.75-inch rod diameter, and a 5-inch free length. The trapezoidal wire shape delivers a higher load capacity per unit of compressed length compared to round-wire springs. With a maximum deflection load of 680.8 pounds and a spring rate of 368 pounds per inch, this spring provides predictable, consistent force output across its 1.85-inch maximum deflection range. It is manufactured from chromium alloy steel for durability under repeated cycling.

This die spring is suited for metal stamping, injection mold tooling, and material handling equipment where controlled return force is required. The red color coding identifies it as a medium heavy-duty rating per industry-standard die spring classifications, allowing quick identification during tooling setup and maintenance. Industrial tooling technicians and machine shop professionals typically install and service these components in production die sets and fixture assemblies.

Key Features

• Trapezoidal wire cross-section delivers higher load capacity compared to standard round-wire die springs
• Maximum deflection load of 680.8 pounds at 1.85 inches of travel
• Spring rate of 368 pounds per inch for predictable, linear force response
• Chromium alloy steel construction for resistance to fatigue and cyclic loading
• Red color coding identifies medium heavy-duty duty rating per standard die spring classification
• Manufactured under ISO 9001:2008 and ISO/TS 16949:2009 certified quality systems, TUV Rheinland registered, and ANAB accredited

Compatibility

Designed as a standard-dimension replacement or new-installation die spring for industrial tooling applications requiring a 1.5-inch hole diameter, 0.75-inch rod diameter, and 5-inch free length in medium heavy-duty configurations.

Installation Notes

Die spring installation and replacement is typically performed by toolroom technicians or industrial maintenance personnel. Before servicing any die set or press tooling, ensure the press is locked out and tagged out per applicable OSHA lockout/tagout procedures. Inspect the mating rod and bore for wear, burrs, or misalignment before seating the spring, as off-axis loading accelerates fatigue failure. Never exceed the specified maximum deflection of 1.85 inches during operation, as over-compression significantly reduces service life.
