Associated Spring 206-710 Die Spring 3 in Extra Strong Yellow

Product Description

The ASSOCIATED SPRING 206-710 is a heavy-duty die spring rated Extra Strong and designed for use in stamping dies, punch presses, and industrial tooling applications. Built from chromium alloy steel with a trapezoidal wire profile, it delivers a maximum deflection load of 7792 newtons across 16 millimeters of travel. The yellow color coding identifies its Extra Strong duty rating at a glance, allowing technicians to quickly verify spring selection during die setup. This spring is intended for installation by tool and die makers, maintenance machinists, and industrial equipment technicians working in metal forming and press tool environments.

This die spring is suited for use in stamping and forming dies, injection mold tooling, and other industrial press applications requiring predictable, high-force spring return. Its 3-inch free length and compact rod and hole geometry make it a common choice for moderate-travel, high-load positions in die assemblies. Compliance with ISO 10243 standards makes it compatible with tooling designed to that specification, simplifying direct substitution in ISO-rated die spring positions.

Key Features

• Extra Strong duty rating with 7792 newtons maximum deflection load
• Trapezoidal wire shape provides higher load capacity relative to round wire springs of the same envelope
• Chromium alloy steel construction for fatigue resistance under cyclic loading
• Yellow color coding for immediate duty-rating identification per ISO 10243 conventions
• 16 millimeters maximum deflection with 3-inch free length
• Conforms to ISO 10243 standard for die spring dimensional and performance specifications

Compatibility

Designed as a direct-fit replacement or new installation die spring for tooling built to ISO 10243 specifications with a 40 millimeter hole diameter and 20 millimeter rod diameter.

Installation Notes

Installation is typically performed by tool and die technicians or maintenance machinists during die build or spring replacement cycles. Always de-energize and lock out the press before accessing the die set. Ensure the spring pocket depth and rod clearance match the free length and rod diameter before seating. Do not compress the spring beyond its rated maximum deflection of 16 millimeters during installation or operation.
