Associated Spring Raymond 106-405 Die Spring Extra Heavy-duty

Product Description

The ASSOCIATED SPRING RAYMOND 106-405 is an extra heavy-duty die spring engineered for high-load stamping, pressing, and tooling applications. Built from chromium alloy steel with a trapezoidal wire cross-section, it delivers a spring rate of 1,100 pounds per inch and supports a maximum deflection load of 343.8 pounds at 0.31 inches of travel. The green color coding identifies it as an extra heavy-duty rating per standard die spring classification. Free length is 1.25 inches, with a 0.75-inch hole diameter and 0.375-inch rod diameter. Licensed machinists, tool and die makers, and press maintenance technicians are the primary installers.

This die spring is suited for use in metal stamping dies, punch press tooling, injection mold assemblies, and industrial fixture applications requiring consistent, high-force return action. Its compact 1.25-inch free length makes it appropriate for tight-clearance die sets where space is limited but load capacity cannot be compromised. It is sold individually and is a direct fit for standard die spring pockets conforming to its listed hole and rod diameter dimensions.

Key Features

• Extra heavy-duty duty rating identified by green color coding
• Trapezoidal wire cross-section provides higher load capacity versus round wire at equivalent size
• Spring rate of 1,100 pounds per inch for predictable, consistent force output
• Maximum deflection load of 343.8 pounds at 0.31 inches travel
• Chromium alloy steel construction for fatigue resistance under cyclic loading
• Manufactured under ISO 9001:2008 and ISO/TS 16949:2009 certified quality systems

Compatibility

Designed as an OEM-style replacement or new installation die spring for standard die sets accepting a 0.75-inch hole diameter and 0.375-inch rod diameter with a 1.25-inch free length in extra heavy-duty green classification.

Installation Notes

Installation is performed by tool and die makers or press maintenance technicians during die set assembly or tooling maintenance. Always de-energize and lock out the press before servicing any die components. Ensure the spring pocket depth and rod clearance match the specified hole diameter, rod diameter, and compressed length before installation. Do not compress the spring beyond its rated maximum deflection of 0.31 inches to avoid permanent set or premature fatigue failure.
