Associated Spring Raymond 104-306 Die Spring Red

Product Description

The ASSOCIATED SPRING RAYMOND 104-306 is a medium heavy-duty die spring engineered for use in stamping dies, punch presses, and precision tooling applications. It features a 0.625-inch hole diameter, a 0.344-inch rod diameter, and a 1.5-inch free length. The trapezoidal wire shape increases surface contact and delivers a spring rate of 190 pounds per inch, with a maximum deflection load of 105.5 pounds at 0.56 inches of travel. Constructed from chromium alloy steel, this spring is color-coded red to indicate medium heavy-duty duty rating, making fast visual identification straightforward during setup and maintenance.

This die spring is suited for industrial tooling environments where consistent, repeatable force is required over high cycle counts. Typical applications include metal stamping dies, injection mold tooling, and mechanical press fixtures. The red color coding aligns with ISO and industry-standard die spring classification systems, allowing tool and die makers and maintenance technicians to quickly match replacement springs to existing tooling without measuring each unit individually.

Key Features

• Trapezoidal wire cross-section increases load-bearing surface area compared to round wire springs
• Spring rate of 190 pounds per inch for predictable, linear force output
• Maximum deflection load of 105.5 pounds at 0.56 inches maximum deflection
• Red color coding identifies medium heavy-duty rating for fast visual sorting
• Chromium alloy steel construction for fatigue resistance in high-cycle tooling
• Manufactured under ISO 9001:2008 and ISO/TS 16949:2009 certified quality systems

Compatibility

Designed as an OEM-style replacement die spring for stamping dies, punch press tooling, and mold fixtures requiring a 0.625-inch hole diameter, 0.344-inch rod diameter, and 1.5-inch free length in a medium heavy-duty rating.

Installation Notes

Installation is typically performed by tool and die makers or industrial maintenance technicians. Always de-energize and lock out the press or mold before replacing die springs. Inspect the mating pocket and guide rod for wear or damage before seating the new spring. Do not compress the spring beyond its rated maximum deflection of 0.56 inches during assembly or operation.
