Associated Spring Raymond 104-518 Die Spring Red

Product Description

The ASSOCIATED SPRING RAYMOND 104-518 is a medium heavy-duty die spring designed for use in stamping dies, molds, and industrial press tooling. It features a 1 inch hole diameter, a 0.5 inch rod diameter, and a free length of 4.5 inches. Constructed from chromium alloy steel with a trapezoidal wire shape, it delivers a maximum deflection load of 283.1 pounds and a maximum deflection of 1.67 inches. The red color designation identifies the medium heavy-duty load rating in the standard die spring classification system. Licensed HVAC, plumbing, and industrial maintenance technicians working on press equipment will encounter this part in high-cycle tooling applications.

This die spring fits standard die sets used in metal stamping, injection mold tooling, and similar industrial press applications. It is suited for environments requiring consistent spring force over repeated cycles. The 4.5 inch free length and 178 lb per inch spring rate make it appropriate for medium to heavy load applications where controlled deflection is critical to tooling performance and part repeatability.

Key Features

• Medium heavy-duty duty rating identified by red color coding
• Trapezoidal wire shape provides higher load capacity relative to wire cross-section
• Chromium alloy steel construction for durability in high-cycle press environments
• Maximum deflection load of 283.1 pounds with 1.67 inches maximum deflection
• Spring rate of 178 pounds per inch for predictable, linear force output
• Manufactured under ISO 9001:2008 and ISO/TS 16949:2009 certified quality systems

Compatibility

Designed as a standard replacement die spring for industrial stamping dies, molds, and press tooling applications requiring a 1 inch hole diameter, 0.5 inch rod diameter, and 4.5 inch free length in the medium heavy-duty load range.

Installation Notes

Die spring installation is performed by toolmakers, tool and die technicians, or qualified industrial maintenance personnel. Ensure the press or die set is fully de-energized and all stored energy is released before replacing any spring component. Verify hole and rod diameter clearances match the replacement spring specifications before seating. Do not compress the spring beyond its rated maximum deflection to avoid permanent set or premature fatigue failure.
