Associated Spring 105-532 Heavy-duty Die Spring Gold

Product Description

The ASSOCIATED SPRING 105-532 is a heavy-duty die spring designed for use in stamping dies, punch presses, and other high-cycle tooling applications. Built from chromium alloy steel with a trapezoidal wire cross-section, this spring delivers a rated spring rate of 192 pounds per inch and a maximum deflection load of 460.8 pounds at 2.4 inches of travel. The gold color coding identifies it as a heavy-duty grade per standard die spring classification. It is sized for a 1-inch hole diameter and a 0.5-inch rod diameter, with an 8-inch free length. Tooling engineers, die setters, and maintenance machinists are the primary installers.

This spring is suited for use in metal stamping dies, injection mold tooling, and general industrial press applications where consistent, high-load return force is required. The heavy-duty rating makes it appropriate for applications with frequent cycling and high compressive loads. Its standard dimensions allow it to drop into existing die sets or custom tooling bores that call for a 1-inch hole and 0.5-inch guide rod configuration.

Key Features

• Heavy-duty duty rating with 460.8-pound maximum deflection load
• Spring rate of 192 pounds per inch for predictable, linear force output
• Trapezoidal wire cross-section increases load capacity relative to round wire at the same envelope size
• Chromium alloy steel construction for fatigue resistance in high-cycle tooling
• Gold color coding identifies heavy-duty grade at a glance during die setup
• Manufactured under ISO 9001:2008 and ISO/TS 16949:2009 certified quality systems

Compatibility

Designed as a standard heavy-duty die spring for tooling applications requiring a 1-inch hole diameter, 0.5-inch rod diameter, and 8-inch free length. Consult the original die design or tooling drawings to confirm load and deflection requirements before installation.

Installation Notes

Die springs should be installed and replaced by qualified tooling technicians or die setters. Always de-energize and lock out the press before servicing any die set. Never compress a die spring beyond its rated maximum deflection of 2.4 inches, as over-compression accelerates fatigue failure. Inspect the guide rod and bore for proper fit and alignment before placing the spring under load.
