Associated Spring Raymond 104-414 Die Spring Red

Product Description

The ASSOCIATED SPRING RAYMOND 104-414 is a medium heavy-duty die spring engineered for high-load tooling and stamping applications. It features a 0.75 inch hole diameter, a 0.375 inch rod diameter, and a 3.5 inch free length. Constructed from chromium alloy steel with a trapezoidal wire profile, this spring delivers a rated spring rate of 128 pounds per inch and a maximum deflection load of 165.8 pounds at 1.3 inches of maximum deflection. The red color coding indicates medium heavy-duty duty rating per standard die spring classification. Tool and die makers, press technicians, and mold maintenance personnel are the primary installers.

This die spring is suited for use in punch-and-die assemblies, injection molds, stamping dies, and similar high-cycle tooling where consistent load and repeatable deflection are required. The trapezoidal wire cross-section increases the active coil volume compared to round wire springs of the same envelope size, supporting higher load capacity within a compact footprint. It is appropriate for both new tooling builds and replacement service in existing die sets across light manufacturing and heavy industrial press environments.

Key Features

• Chromium alloy steel construction for high fatigue resistance under cyclic loading
• Trapezoidal wire profile increases load capacity within the same outer diameter envelope
• 128 pounds per inch spring rate for predictable, linear force response
• 165.8 pound maximum deflection load at 1.3 inches maximum deflection
• Red color coding identifies medium heavy-duty rating for fast visual selection
• Manufactured under ISO 9001:2008 and ISO/TS 16949:2009 certified quality systems

Compatibility

Designed as an OEM-style replacement or new-build component for die sets and tooling assemblies requiring a 0.75 inch hole diameter, 0.375 inch rod diameter, medium heavy-duty die spring with a 3.5 inch free length.

Installation Notes

Installation is performed by qualified tool and die technicians or press maintenance personnel. Always de-energize and lock out the press before accessing the die set. Ensure the mating rod and bore dimensions match the spring specifications to prevent side loading or buckling during compression. Do not compress the spring beyond the rated maximum deflection of 1.3 inches, as exceeding this limit can cause permanent set or premature fatigue failure.
