Associated Spring Raymond 204-205 Die Spring Blue

Product Description

The ASSOCIATED SPRING RAYMOND 204-205 is a blue-coded die spring engineered for high-cycle tooling and stamping die applications. It features a trapezoidal wire cross-section that delivers greater load capacity and longer fatigue life compared to round-wire springs of the same envelope size. The free length is 1.25 inches (32 millimeters) with a rod diameter of 6.30 millimeters and a hole diameter of 12.50 millimeters. Maximum deflection is 12.20 millimeters, with a spring rate of 141.61 newtons per millimeter and a maximum deflection load of 302.60 newtons. The blue color designation indicates a medium load classification per ISO 10243.

This spring is used in metal stamping dies, injection mold tooling, punch and die sets, and precision industrial fixtures where consistent, repeatable spring force is required. It is appropriate for both short-run prototype tooling and high-volume production dies. Toolmakers, die setters, and maintenance machinists typically specify and install this component. It suits applications requiring a compact, high-load spring within a standard die pocket geometry.

Key Features

• Trapezoidal wire shape provides higher load density and extended fatigue life versus round-wire alternatives
• Blue color coding identifies medium load classification per ISO 10243 standard
• Chromium alloy steel construction for durability in high-cycle die applications
• Spring rate of 141.61 newtons per millimeter for consistent, predictable force output
• Manufactured under ISO 9001:2008 and ISO/TS 16949:2009 quality systems with TUV Rheinland registration and ANAB accreditation
• ISO 10243 compliant geometry for interchangeability with other standard die spring formats

Compatibility

Designed as an ISO 10243 standard die spring replacement for medium-load applications using a 12.50 millimeter hole diameter and 6.30 millimeter rod diameter, compatible with standard die pockets in metal stamping and injection molding tooling.

Installation Notes

Installation is typically performed by toolmakers or die maintenance technicians. Ensure the die pocket and guide rod are clean and free of burrs before seating the spring. Do not exceed the rated maximum deflection of 12.20 millimeters, as over-compression will shorten fatigue life and may cause failure. De-energize and lock out any associated press or clamping equipment before replacing die springs.
