Associated Spring Raymond 203-620 Die Spring 5 in Green

Product Description

The ASSOCIATED SPRING RAYMOND 203-620 is a heavy-duty die spring engineered for use in stamping dies, metal forming tooling, and industrial press applications. It features a trapezoidal wire cross-section that maximizes contact area and delivers consistent force output over extended cycle life. At 5 inches free length with a spring rate of 142.75 N/mm, this green-coded spring falls in the heavy load classification under ISO 10243. The 203-620 is manufactured from chromium alloy steel and produced under ISO 9001:2008 and ISO/TS 16949:2009 certified quality systems. Die maintenance technicians, toolmakers, and press room personnel are the primary installers.

This die spring is suited for use in progressive dies, compound dies, and stripper plate assemblies in both production stamping and short-run tooling environments. The green color code identifies it as a heavy-load spring per the ISO 10243 standard, making it straightforward to cross-reference during die repair or rebuild work. A rod diameter of 16 mm and hole diameter of 32 mm define the mounting envelope. Maximum deflection is 51 mm with a corresponding maximum deflection load of 1275 N, giving toolmakers a clear working range for die design and maintenance scheduling.

Key Features

• Trapezoidal wire shape increases load-bearing surface area for higher cycle durability compared to round wire springs
• Green color coding indicates heavy-load classification per ISO 10243 for quick field identification
• 5-inch (127 mm) free length with 51 mm maximum deflection travel to solid
• Spring rate of 142.75 N/mm for predictable, repeatable force output
• Chromium alloy steel construction for high fatigue resistance in continuous press operations
• Manufactured under ISO 9001:2008 and ISO/TS 16949:2009 certified quality management systems

Compatibility

Designed as an ISO 10243-compliant heavy-load die spring suitable for use in standard die sets and tooling assemblies requiring a 32 mm hole diameter, 16 mm rod diameter, and 127 mm free length.

Installation Notes

Die springs are installed and serviced by toolmakers or press room maintenance personnel during die assembly or rebuild. Before replacing a die spring, lock out and tag out the press per applicable safety procedures and relieve any stored energy in the die. Inspect the rod and hole bores for wear or misalignment that could cause the spring to bind or buckle under load. Do not compress the spring beyond its rated maximum deflection of 51 mm, as operating beyond this point can cause permanent set or premature failure.
