Associated Spring Raymond 203-414 Die Spring 3.5 in Green

Product Description

The ASSOCIATED SPRING RAYMOND 203-414 is a heavy-duty die spring engineered for use in stamping dies, molds, and press tooling applications. It features a trapezoidal wire cross-section, which increases the load-bearing surface area compared to round-wire springs and allows for higher force output within a compact envelope. The spring measures 3.5 inches (89 mm) free length, accommodates a 10 mm guide rod, and fits a 20 mm hole diameter. At maximum deflection of 35 mm, it delivers a load of 490 newtons. Manufactured from chromium alloy steel and color-coded green to indicate load category, this spring is a standard component for tool and die work.

This die spring is suited for industrial press tooling, injection mold assemblies, and stamping fixtures where consistent, repeatable spring force is required. The green color designation corresponds to a light-to-medium load range under ISO 10243 standards, making it appropriate for applications where controlled deflection and predictable spring rate are critical. Toolmakers, die setters, and machine maintenance technicians are the primary installers. It is commonly specified in both OEM tooling builds and replacement maintenance cycles on existing press equipment.

Key Features

• Trapezoidal wire shape provides higher load capacity and longer fatigue life versus standard round-wire die springs
• Green color coding conforms to ISO 10243 load classification for straightforward field identification
• 3.5 inch free length with 35 mm maximum deflection travel
• Fits 10 mm guide rod and 20 mm hole diameter for direct drop-in installation
• Chromium alloy steel construction for resistance to fatigue and set under repeated cycling
• Manufactured under ISO 9001:2008, ISO/TS 16949:2009, and TUV Rheinland registered quality systems

Compatibility

Designed as an ISO 10243-compliant replacement die spring for stamping dies, molds, and press tooling requiring a 20 mm hole diameter, 10 mm rod diameter, and 3.5 inch free length in the green load category.

Installation Notes

Installation is typically performed by tool and die technicians or machine maintenance personnel. Before replacing a die spring, de-energize and lock out the press per facility LOTO procedures and relieve all stored mechanical energy in the tooling. Ensure the guide rod and hole bore are clean and within dimensional tolerance before seating the spring. Never stack die springs unless the tooling design explicitly specifies it, as uneven load distribution can cause premature failure.
