Associated Spring Raymond 203-418 Die Spring 4.5 in Green

Product Description

The ASSOCIATED SPRING RAYMOND 203-418 is a green-coded die spring engineered for use in stamping dies, molds, and industrial tooling applications. With a free length of 4.5 inches (115 mm) and a trapezoidal wire cross-section, this spring delivers consistent force under cyclic compression loads. It carries a spring rate of 62.24 N/mm and a maximum deflection load of 501.40 N at full travel of 46 mm. The chromium alloy steel construction provides durability under high-cycle tooling conditions. Maintenance technicians and toolmakers working in die shops and manufacturing environments are the primary installers of this component.

This die spring is suited for use in punch and die assemblies, injection mold tooling, and stamping press fixtures where controlled return force is required. The green color designation indicates a light-duty load rating within the ISO 10243 die spring classification system. It is appropriate for applications requiring a 20 mm hole diameter and a 10 mm rod diameter, making it compatible with standard die set configurations that fall within those dimensional parameters.

Key Features

• Trapezoidal wire cross-section provides higher load capacity per unit length compared to round wire die springs
• Free length of 4.5 inches (115 mm) suits standard die set pocket depths
• Maximum deflection of 46 mm with a maximum deflection load of 501.40 N
• Spring rate of 62.24 N/mm for predictable, repeatable force output
• Chromium alloy steel construction for extended service life in high-cycle tooling
• Manufactured to ISO 10243 standards with ANAB, ISO 9001:2008, ISO/TS 16949:2009, and TUV Rheinland certifications

Compatibility

Designed as an ISO 10243 compliant die spring for use in tooling applications requiring a 20 mm hole diameter and 10 mm rod diameter. The green light-load classification aligns with standard die spring interchangeability specifications under ISO 10243.

Installation Notes

Die spring installation is typically performed by toolmakers or maintenance technicians during die assembly or rebuild. Ensure the die pocket and guide rod dimensions match the spring specifications before installation. Compress and release the spring several times to verify smooth travel before placing the tooling into production. Never exceed the maximum deflection travel listed for this spring, as overcompression can cause premature failure or damage to the die set.
