Associated Spring Raymond 203-818 Die Spring 4.5 in

Product Description

The ASSOCIATED SPRING RAYMOND 203-818 is a light-duty die spring designed for use in stamping dies, press tooling, and similar industrial applications requiring controlled compression force. Constructed from chromium alloy steel and color-coded green to indicate its light-duty load rating, this spring features a trapezoidal wire cross-section that delivers consistent deflection performance. It has a free length of 4.5 inches (115 mm), a rod diameter of 25 mm, and a hole diameter of 50 mm. Maximum deflection load reaches 837.64 pounds (3726 N) at full travel, with a travel-to-solid distance of 46 mm. Die makers, tooling technicians, and maintenance personnel in manufacturing environments install this type of spring as part of die sets and press assemblies.

This die spring is suited for light-duty stamping and forming dies in industrial press applications. The green color coding follows ISO 10243 standards, making it straightforward to identify and replace within a multi-spring die set. Typical installation environments include metal stamping shops, fabrication facilities, and tool-and-die operations where repeatable spring force and consistent travel are critical to part quality and die longevity.

Key Features

• Light-duty load rating with green color coding per ISO 10243
• Trapezoidal wire cross-section for higher load capacity versus round wire at equivalent size
• Chromium alloy steel construction for durability under cyclic compression
• 4.5-inch free length with 46 mm travel to solid
• Maximum deflection load of 837.64 pounds (3726 N)
• 25 mm rod diameter and 50 mm hole diameter for standard die set fitment

Compatibility

Designed as an ISO 10243-compliant light-duty die spring for use in standard stamping die sets with a 25 mm rod diameter and 50 mm hole diameter.

Installation Notes

Die springs are installed by tool-and-die technicians or qualified press maintenance personnel. Always de-energize and lock out the press before servicing any die components. Confirm the rod and hole diameters of the die set match the spring specifications before installation. Do not compress the spring beyond its rated travel-to-solid distance, as over-compression can cause premature fatigue or failure.
