Associated Spring Raymond 203-107 Die Spring 1-3/4 in

Product Description

The ASSOCIATED SPRING RAYMOND 203-107 is a green-coded die spring designed for use in stamping dies, molds, and tooling fixtures where controlled, repeatable compression force is required. Built from chromium alloy steel with a trapezoidal wire cross-section, this spring delivers a spring rate of 34.26 N/mm and a maximum deflection load of 108 newtons over an 18 mm travel-to-solid range. The 1-3/4 inch (44 mm) free length and green color coding follow ISO 10243 standards, making it straightforward to identify and replace in multi-spring tooling setups. Die makers, tool-and-die technicians, and press maintenance personnel are the typical installers.

This die spring fits applications in metal stamping, injection mold tooling, and precision fixture work where a light-load, high-cycle spring is needed. The 10 mm hole diameter and 5 mm rod diameter define the mounting envelope, so it is suited for smaller-bore die sets and modular tooling plates. The green color designation indicates a light-duty load category per ISO 10243, appropriate for stripper plates, guide pin returns, and similar low-force cycling applications in both production and prototype tooling environments.

Key Features

• Trapezoidal wire cross-section provides higher load capacity per unit length compared to round wire die springs of the same envelope
• Green color coding indicates light-load category per ISO 10243 for quick visual identification in the toolroom
• Chromium alloy steel construction supports high-cycle fatigue resistance in stamping and molding environments
• Maximum deflection of 18 mm at 108 newtons load with a linear spring rate of 34.26 N/mm
• Manufactured under ISO 9001:2008 and ISO/TS 16949:2009 certified quality systems with TUV Rheinland registration
• ANAB accredited and ISO 10243 compliant for dimensional and performance interchangeability

Compatibility

Designed as an ISO 10243 compliant die spring for use in stamping dies, molds, and tooling fixtures requiring a 10 mm hole diameter and 5 mm rod diameter mounting configuration in the light-load (green) category.

Installation Notes

Die springs are installed by tool-and-die technicians and press maintenance personnel. Always de-energize and lock out the press or machine before removing or replacing springs in any die or mold assembly. Ensure the spring bore and rod diameters match the pocket and guide pin dimensions before seating to prevent binding or off-axis loading. Never compress a die spring beyond its travel-to-solid length, as doing so will cause permanent damage and premature fatigue failure.
