Associated Spring Raymond 105-412 Heavy-duty Die Spring

Product Description

The ASSOCIATED SPRING RAYMOND 105-412 is a heavy-duty die spring engineered for use in stamping dies, punch presses, and industrial tooling applications. Built from chromium alloy steel with a trapezoidal wire cross-section, this spring delivers a maximum deflection load of 306 pounds at a maximum deflection of 0.9 inches, with a spring rate of 330 pounds per inch. The gold color coding identifies it as a heavy-duty rated spring in the standard ISO die spring color classification system. It has a 3/4-inch hole diameter, a 3/8-inch rod diameter, and a 3-inch free length. Tool and die makers, press operators, and maintenance machinists are the typical end users for this component.

This die spring is intended for installation in stamping dies, injection molds, and mechanical presses where consistent, repeatable spring force is required under cyclic compression loads. The 3-inch free length and heavy-duty rating make it suitable for applications demanding higher load capacity within a compact envelope. It is sold individually and is appropriate for both OEM die builds and replacement maintenance in production environments.

Key Features

• Heavy-duty duty rating with a 306-pound maximum deflection load
• Trapezoidal wire cross-section for higher load density compared to round wire springs of the same envelope
• Chromium alloy steel construction for wear resistance and fatigue life under cyclic loading
• Gold color coding for quick identification per ISO die spring classification standards
• Spring rate of 330 pounds per inch for predictable, linear force characteristics
• Manufactured under ISO 9001:2008 and ISO/TS 16949:2009 certified quality systems with TUV Rheinland registration

Compatibility

Designed as a standard heavy-duty die spring for use in stamping dies, punch presses, injection molds, and similar industrial tooling where a 3/4-inch hole diameter and 3/8-inch rod diameter spring seat is specified.

Installation Notes

Installation is performed by tool and die makers or maintenance machinists during die build or scheduled press maintenance. Always de-energize and lock out the press or machine before removing or installing die springs. Inspect the spring seat, guide rod, and bore for wear or misalignment before installing a replacement spring. Do not compress the spring beyond its rated maximum deflection of 0.9 inches, as exceeding this limit will reduce fatigue life and can cause premature failure.
