Associated Spring Raymond 203-618 Die Spring 4.5 in

Product Description

The ASSOCIATED SPRING RAYMOND 203-618 is a light-duty die spring designed for use in stamping dies, punch presses, and tooling fixtures where consistent, controlled compression force is required. Built from chromium alloy steel with a trapezoidal wire profile, this spring delivers a maximum deflection load of 299.90 pounds (1334 newtons) over a maximum deflection of 46 millimeters. The 4.5-inch (115 mm) free length and green color coding make it straightforward to identify and source during die maintenance. Tool and die makers, press operators, and industrial maintenance technicians are the primary installers of this component.

This spring fits applications calling for a 32 mm hole diameter and a 16 mm rod diameter, conforming to ISO 10243 standards for die springs. It is suited for light-duty cycling applications in metal stamping, forming, and injection mold tooling where precise spring return forces are needed. The green color designation per ISO 10243 indicates the light-duty load rating, making it easy to match replacement springs to existing tooling specifications without measuring every time.

Key Features

• ISO 10243 compliant light-duty die spring for standardized tooling interchangeability
• Trapezoidal wire cross-section provides higher load capacity and longer fatigue life compared to round wire at equivalent sizes
• Chromium alloy steel construction for durability under repeated compression cycling
• Green color coding identifies light-duty load rating at a glance during maintenance
• Maximum deflection load of 299.90 lb (1334 N) with 46 mm travel to solid
• 4.5-inch (115 mm) free length fits standard die set configurations using 32 mm hole and 16 mm rod dimensions

Compatibility

Designed as an ISO 10243 compliant replacement die spring for light-duty tooling applications requiring a 32 mm hole diameter, 16 mm rod diameter, and 4.5-inch free length.

Installation Notes

Die springs are installed and replaced by tool and die makers or industrial maintenance technicians during scheduled die maintenance or after spring failure. Always de-energize and lock out the press before accessing the die set. Confirm hole diameter, rod diameter, free length, and duty rating against the existing tooling specifications before installation. Do not exceed the rated maximum deflection to avoid premature spring fatigue or failure.
