Associated Spring Raymond 206-305 Die Spring Yellow

Product Description

The ASSOCIATED SPRING RAYMOND 206-305 is an extra-strong die spring designed for high-load tooling and stamping die applications. It features a 16.00 mm hole diameter, an 8.00 mm rod diameter, and a free length of 1-1/4 inches (32.00 mm). The trapezoidal wire cross-section delivers a higher spring rate compared to round-wire designs, and the chromium alloy steel construction resists fatigue under repeated compression cycles. With a spring rate of 508.20 N/mm and a maximum deflection load of 712.00 N, this spring is suited for applications that demand consistent, repeatable force output. Die makers, tool and die technicians, and maintenance machinists are the primary installers.

This die spring is used in punch and die sets, injection molds, stamping presses, and similar precision tooling assemblies where controlled return force is required. The yellow color coding indicates the extra-strong duty rating, allowing quick visual identification during tooling setup and maintenance. Maximum deflection is 8.00 mm at a load of 712.00 N, making this spring appropriate for compact tooling cavities with limited travel. It is manufactured to ISO 10243 standards, ensuring dimensional consistency and performance interchangeability with other ISO-compliant die spring designs.

Key Features

• Extra-strong duty rating with a spring rate of 508.20 N/mm for high-load tooling applications
• Trapezoidal wire shape increases load capacity versus conventional round-wire die springs
• Chromium alloy steel construction for fatigue resistance under cyclic compression
• Yellow color coding for quick visual identification of duty rating on the shop floor
• Manufactured to ISO 10243 for dimensional interchangeability
• Certified under ISO 9001:2008 and ISO/TS 16949:2009 quality management standards

Compatibility

Designed as an ISO 10243-compliant replacement or new-installation die spring for punch and die tooling assemblies requiring a 16.00 mm hole diameter, 8.00 mm rod diameter, and 32.00 mm free length in an extra-strong duty rating.

Installation Notes

Die springs are installed and serviced by tool and die technicians and maintenance machinists. Always relieve all press or clamp pressure and de-energize the machine before removing or installing die springs. Inspect the mating rod and hole dimensions for proper clearance before installation; running a spring on an undersized rod or in an oversized bore can cause lateral loading and premature fatigue failure. Springs should be replaced as a matched set within a die to maintain balanced load distribution.
