Associated Spring Raymond 203-105 Die Spring

Product Description

The ASSOCIATED SPRING RAYMOND 203-105 is a die spring manufactured from chromium alloy steel with a trapezoidal wire cross-section. It has a free length of 1-1/4 inches (32 mm) and a rod diameter of 5 mm, with a hole diameter of 10 mm. The green color coding indicates its load category per ISO 10243. This spring delivers a maximum deflection load of 111.40 N over a maximum deflection of 13.10 mm, with a spring rate of 48.54 N/mm. It is installed by toolmakers, die setters, and maintenance technicians working on stamping, forming, and injection mold tooling.

This die spring is suited for use in metal stamping dies, plastic injection molds, punching tools, and general industrial press tooling. The compact free length and precise load characteristics make it appropriate for stripper plate applications and component return functions in progressive and compound dies. It is compatible with standard die sets requiring a 10 mm hole diameter and 5 mm rod diameter per ISO 10243 specifications.

Key Features

• Chromium alloy steel construction for high fatigue life in cyclic press applications
• Trapezoidal wire cross-section provides higher load capacity relative to round-wire springs of the same envelope
• Green color code denotes light load category per ISO 10243
• Free length of 1-1/4 inches (32 mm) with 13.10 mm maximum deflection to solid
• Spring rate of 48.54 N/mm for predictable, consistent force output
• Manufactured under ISO 9001:2008 and ISO/TS 16949:2009 certified quality systems

Compatibility

Designed as a replacement or service spring for die sets requiring a 10 mm hole diameter and 5 mm rod diameter conforming to ISO 10243 die spring standards.

Installation Notes

Die springs are installed by toolmakers and die maintenance technicians. Always de-energize and lock out press equipment before replacing or inspecting die springs. Ensure the spring pocket and rod dimensions match the hole diameter and rod diameter specified for this part before installation. Do not compress beyond the rated maximum deflection to avoid coil clash and premature fatigue failure.
