Associated Spring Raymond 203-305 Die Spring 1-1/4 in

Product Description

The ASSOCIATED SPRING RAYMOND 203-305 is a green-coded die spring designed for use in stamping dies, molds, and tooling fixtures where consistent, high-cycle compression force is required. Built from chromium alloy steel with a trapezoidal wire cross-section, it delivers a spring rate of 130.76 N/mm and a maximum deflection load of 300 newtons over 13.10 millimeters of travel. The green color coding follows ISO 10243 standards, indicating a light-load designation. This spring is installed by tool and die makers, mold technicians, and maintenance machinists working in press tooling and injection mold applications.

This die spring is suited for light-duty cycling applications in stamping dies, progressive dies, and mold assemblies. The 16.00 mm hole diameter and 8.00 mm rod diameter make it compatible with standard ISO 10243 die spring pockets. It is a direct-fit replacement wherever a green-series ISO die spring of 32.00 mm free length is specified. Tool rooms, production stamping operations, and mold shops are the typical service environments.

Key Features

• Trapezoidal wire cross-section for higher load capacity versus round-wire springs of the same envelope
• Green color code identifies light-load series per ISO 10243
• Chromium alloy steel construction for durability in high-cycle tooling applications
• 13.10 mm maximum deflection with 300 N maximum deflection load
• Manufactured under ISO 9001:2008 and ISO/TS 16949:2009 certified quality systems
• TUV Rheinland registered and ANAB accredited production standards

Compatibility

Designed as an OEM-style replacement for green-series die springs conforming to ISO 10243, with a 16.00 mm hole diameter and 8.00 mm rod diameter.

Installation Notes

Die springs are installed and replaced by tool and die makers or maintenance technicians during scheduled tooling maintenance or at end-of-service-life intervals. Always de-energize and lock out the press or mold clamp before removing or installing die springs. Inspect the spring pocket and guide rod for wear or damage before installing a new spring. Never compress a die spring beyond its rated maximum deflection to avoid premature failure or tooling damage.
