Associated Spring Raymond 206-307 Die Spring 1-3/4 in

Product Description

The ASSOCIATED SPRING RAYMOND 206-307 is a yellow-coded die spring designed for use in stamping dies, molds, and industrial tooling applications. Built from chromium alloy steel with a trapezoidal wire cross-section, it delivers consistent force and controlled deflection under high-cycle conditions. The spring has a free length of 1-3/4 inches (44 mm), a rod diameter of 8 mm, and a hole diameter of 16 mm. With a spring rate of 347.75 N/mm and a maximum deflection load of 669.90 N over 11 mm of travel, it is sized for moderate-load tooling setups. Licensed machinists, tool and die makers, and maintenance technicians are the primary installers.

This die spring is suited for use in punch and die assemblies, injection mold stripper plates, and general industrial press tooling where repeatable spring force is required. The yellow color coding follows the ISO 10243 standard, indicating a light-load designation within the color-coded die spring classification system. It is appropriate for both OEM tooling builds and replacement applications in production environments.

Key Features

• Chromium alloy steel construction for durability under high-cycle fatigue conditions
• Trapezoidal wire cross-section provides higher load capacity relative to round wire at the same coil dimensions
• Yellow color coding per ISO 10243 for quick visual identification of load class
• Free length of 1-3/4 inches (44 mm) with 11 mm maximum deflection
• Spring rate of 347.75 N/mm for predictable, linear force output
• Manufactured under ISO 9001:2008 and ISO/TS 16949:2009 certified quality systems with TUV Rheinland registration

Compatibility

Designed as an ISO 10243-compliant replacement or OEM-specification die spring for light-load stamping dies, molds, and press tooling requiring a 16 mm hole diameter and 8 mm rod diameter with a 44 mm free length.

Installation Notes

Die springs should be installed by qualified tool and die makers or industrial maintenance technicians familiar with press tooling. Always de-energize and lock out the press before accessing the die assembly. Ensure the mating rod and hole diameters match the spring specifications before installation to prevent buckling or premature failure. Do not compress the spring beyond its rated maximum deflection of 11 mm.
