Associated Spring Raymond 205-412 Heavy-duty Die Spring

Product Description

The ASSOCIATED SPRING RAYMOND 205-412 is a heavy-duty die spring engineered for use in stamping dies, punch presses, and metal-forming tooling. Built from chromium alloy steel and finished in red to indicate heavy-duty load rating, this spring delivers consistent force across repeated compression cycles. It features a trapezoidal wire cross-section that maximizes load capacity within the spring envelope. Key performance values include a maximum deflection load of 308.69 pounds (1373.10 N) and a travel-to-solid distance of 23.00 mm. Toolmakers, die setters, and precision machinists install this spring where reliable, high-cycle performance is required in industrial press tooling.

This die spring is suited for heavy-duty tooling applications in metal stamping, injection mold tooling, and industrial press equipment. The red color coding follows ISO 10243 classification standards, identifying it as a heavy-duty series spring. With a 20.00 mm hole diameter and 10.00 mm rod diameter, it fits standard die spring pockets and guide rods common in production tooling setups. A free length of 76.00 mm (3 inches) makes it appropriate for applications requiring moderate spring travel with high return force.

Key Features

• Heavy-duty load rating with a maximum deflection load of 308.69 pounds (1373.10 N)
• Trapezoidal wire cross-section maximizes load density within the spring diameter
• Chromium alloy steel construction for durability in high-cycle tooling environments
• Red color coding per ISO 10243 for quick identification of duty class in the field
• 23.00 mm maximum deflection (travel to solid) provides controlled compression stroke
• Fits 20.00 mm hole diameter and 10.00 mm guide rod diameter

Compatibility

Designed as an ISO 10243-compliant heavy-duty die spring for use with standard 20.00 mm bore die spring pockets and 10.00 mm guide rods in industrial stamping and metal-forming tooling.

Installation Notes

Die springs are installed by toolmakers and die setters during press tool assembly or maintenance. Always de-energize and lock out the press before accessing the die set. Inspect the spring pocket bore and guide rod for wear or damage prior to installation, as misalignment accelerates fatigue. Never compress a die spring beyond its rated travel-to-solid distance, as solid-loading will cause premature failure.
