Associated Spring Raymond 206-406 Die Spring Extra Strong

Product Description

The ASSOCIATED SPRING RAYMOND 206-406 is a heavy-duty die spring engineered for use in stamping dies, press tooling, and industrial mold assemblies. Built from chromium alloy steel with a trapezoidal wire cross-section, this spring delivers an Extra Strong duty rating with a maximum deflection load of 378.02 pounds (1681.50 N). The free length is 1.5 inches (38.00 mm), and maximum deflection travel is 9.50 mm. The yellow color coding conforms to ISO 10243 standards for quick identification of spring duty class in high-volume tooling environments. Licensed tool and die makers, press technicians, and industrial maintenance professionals install this part.

This die spring is designed for applications where consistent, high-force return action is required across repeated press cycles. Typical uses include punch and die sets, injection mold tooling, and progressive die assemblies in manufacturing and fabrication environments. The ISO 10243 designation ensures dimensional interchangeability within the standard die spring system, making it a direct fit in tooling designed around that specification. It is suited to both light production and high-cycle industrial press applications wherever an Extra Strong yellow-class spring is specified.

Key Features

• Extra Strong duty rating with a maximum deflection load of 378.02 pounds (1681.50 N)
• Trapezoidal wire cross-section provides higher load capacity relative to round-wire springs of the same envelope
• Chromium alloy steel construction for durability under high-cycle fatigue conditions
• Yellow color coding per ISO 10243 for fast visual identification of duty class
• 1.5-inch (38.00 mm) free length with 9.50 mm travel to solid load
• Compatible hole diameter of 20.00 mm and rod diameter of 10.00 mm for precise tooling fit

Compatibility

Designed as an ISO 10243-compliant die spring for use in stamping dies, molds, and press tooling built to accept a 20.00 mm hole diameter and 10.00 mm rod diameter Extra Strong yellow-class spring.

Installation Notes

Installation is typically performed by tool and die makers or maintenance technicians during die setup or spring replacement. Always ensure the press or mold is fully de-energized and at zero pressure before removing or replacing die springs. Inspect the mating hole and rod dimensions against the 20.00 mm hole diameter and 10.00 mm rod diameter specifications before installation. Do not exceed the rated maximum deflection of 9.50 mm, as over-compression will reduce spring service life and can cause premature failure.
