Associated Spring Raymond 105-406 Die Spring Heavy Duty Gold

Product Description

The ASSOCIATED SPRING RAYMOND 105-406 is a heavy-duty die spring engineered for use in stamping, forming, and pressing tooling applications. Built from chromium alloy steel with a trapezoidal wire profile, this spring delivers a spring rate of 690 pounds per inch and a maximum deflection load of 295.2 pounds at a maximum deflection of 0.45 inches. The gold color coding indicates a heavy-duty load class, following standard die spring classification conventions. It is designed for installation by tool and die makers, press technicians, and industrial maintenance professionals who require consistent, repeatable force characteristics under cyclic loading.

This die spring is suited for use in punch press dies, injection molds, and mechanical tooling assemblies wherever a 0.75-inch hole diameter and 0.375-inch rod diameter configuration is required. The 1.5-inch free length makes it appropriate for compact die sets with limited installation depth. It ships in single-unit quantities and carries a minimum order quantity of one.

Key Features

• Heavy-duty load class indicated by gold color coding
• Trapezoidal wire cross-section for higher load capacity relative to round-wire springs
• Spring rate of 690 pounds per inch for consistent, predictable force output
• Maximum deflection load of 295.2 pounds at 0.45 inches deflection
• Chromium alloy steel construction for fatigue resistance under cyclic press loads
• Meets ISO 9001:2008 and ISO/TS 16949:2009 quality standards; TUV Rheinland Registered

Compatibility

Designed as a direct-fit replacement or original-equipment die spring for tooling assemblies requiring a 0.75-inch hole diameter, 0.375-inch rod diameter, and 1.5-inch free length in a heavy-duty gold-class configuration.

Installation Notes

Installation and replacement of die springs should be performed by qualified tool and die technicians with the press or tooling fully de-energized and locked out per applicable OSHA lockout/tagout procedures. Always verify hole diameter, rod diameter, free length, and load class before substituting a spring in an existing die set. Never compress a die spring beyond its rated maximum deflection, as exceeding this limit accelerates fatigue and can cause premature failure. Inspect mating components including guide posts and bores for wear or misalignment before installing a new spring.
