Associated Spring Raymond 203-212 Die Spring 3 in Green

Product Description

The ASSOCIATED SPRING RAYMOND 203-212 is a heavy-duty die spring designed for use in metal stamping dies, punch presses, and tooling fixtures that demand consistent, repeatable force over long service cycles. Built from chromium alloy steel with a trapezoidal wire cross-section, it delivers a spring rate of 40.54 N/mm across a free length of 3 inches (76 mm). The green color coding follows the ISO 10243 standard, indicating a medium-light load class. This spring fits a 12.50 mm hole diameter and operates over a 6.30 mm rod diameter, making it straightforward to specify and install in standard die sets. Tool and die makers, press room technicians, and precision machining professionals are the primary installers.

This die spring is suited for industrial tooling applications including progressive dies, compound dies, stripper plate assemblies, and other spring-loaded die components in both production stamping and prototype tooling environments. Its 31.20 mm maximum deflection and 221.50 N maximum deflection load make it appropriate for moderate-load applications where controlled spring travel is critical to part quality and die longevity. It is used in both OEM die builds and maintenance replacement scenarios across manufacturing facilities.

Key Features

• Trapezoidal wire cross-section provides higher load capacity per unit length compared to round wire springs of the same envelope size
• Chromium alloy steel construction for durability under high-cycle stamping loads
• Green color code per ISO 10243 for quick visual identification of load class during die setup and maintenance
• 31.20 mm maximum deflection with 221.50 N maximum deflection load for predictable, consistent force output
• Manufactured under ISO 9001:2008 and ISO/TS 16949:2009 certified quality systems with TUV Rheinland registration
• ANAB accredited production ensures dimensional and performance consistency across production lots

Compatibility

Designed as a direct-fit replacement or new-build component for standard die spring pockets accepting a 12.50 mm hole diameter and 6.30 mm rod diameter per ISO 10243 specifications.

Installation Notes

Die springs of this type are installed by tool and die makers or press room maintenance technicians with the press fully de-energized and all stored energy released from the tooling. Ensure the spring pocket depth and rod length provide adequate guidance to prevent buckling at full deflection. Do not compress the spring beyond its rated maximum deflection of 31.20 mm, as over-compression will reduce fatigue life significantly. Inspect springs for set, cracking, or corrosion during scheduled die maintenance intervals.
