Associated Spring Raymond 104-718 Die Spring Red

Product Description

The ASSOCIATED SPRING RAYMOND 104-718 is a medium heavy-duty die spring designed for use in stamping dies, press tooling, and industrial machine assemblies. It features a 1-1/2 inch hole diameter, a 3/4 inch rod diameter, and a 4-1/2 inch free length. The trapezoidal wire shape maximizes load capacity within the spring's cross-section, allowing a maximum deflection load of 719.3 pounds at 1.67 inches of maximum deflection. Constructed from chromium alloy steel, this spring is built to withstand high-cycle fatigue loads common in die and press applications. Machinists, tool and die makers, and industrial maintenance technicians are the primary installers.

This die spring is suited for use in punch and die sets, injection mold assemblies, industrial presses, and similar tooling where consistent spring force and dimensional accuracy are required. The red color designation identifies it as a medium heavy-duty rating, consistent with ISO and industry color-coding conventions for die springs. Its 4-1/2 inch free length and 3/4 inch rod diameter make it a straightforward fit in standard die spring pockets machined to those dimensions.

Key Features

• Medium heavy-duty duty rating with a maximum deflection load of 719.3 pounds
• Trapezoidal wire cross-section for higher load capacity relative to spring size
• Chromium alloy steel construction for fatigue resistance in high-cycle applications
• 1.67 inches maximum deflection with a spring rate of 410 pounds per inch
• Red color coding identifies medium heavy-duty rating for fast field identification
• Certified to ISO 9001:2008 and ISO/TS 16949:2009; TUV Rheinland Registered; ANAB Accredited

Compatibility

Designed for use in standard die spring applications requiring a 1-1/2 inch hole diameter, 3/4 inch rod diameter, and 4-1/2 inch free length in medium heavy-duty tooling setups.

Installation Notes

Die spring installation is typically performed by tool and die makers or qualified industrial maintenance technicians. Always relieve all press or clamp pressure and de-energize associated equipment before removing or replacing die springs. Inspect the spring pocket and guide rod for wear or damage prior to installation. Do not compress a die spring beyond its rated maximum deflection, as over-compression will reduce service life and can cause spring failure.
