Associated Spring Raymond 205-312 Die Spring 3 in Red

Product Description

The ASSOCIATED SPRING RAYMOND 205-312 is a heavy-duty die spring designed for use in stamping dies, press tooling, and industrial mold applications. It features a trapezoidal wire cross-section, which delivers higher load capacity relative to its footprint compared to round-wire springs. The spring has a free length of 3 inches (76 mm), a rod diameter of 8 mm, and a hole diameter of 16 mm, making it straightforward to fit into standard die sets. With a spring rate of 146.75 N/mm and a maximum deflection of 22.80 mm, this unit is sized for moderate-to-heavy cycling loads. It is manufactured from chromium alloy steel and color-coded red for easy load-class identification on the shop floor.

This die spring is used in metal stamping, injection molding, and industrial press tooling where consistent return force and long cycle life are required. The red color designation indicates its load class within the standard die spring color-coding system, helping toolmakers quickly select and organize springs during die builds and maintenance. It is typically installed and serviced by toolmakers, die setters, and industrial maintenance technicians working in manufacturing and fabrication environments.

Key Features

• Trapezoidal wire shape provides higher load capacity per unit space compared to round-wire designs
• 3-inch (76 mm) free length suits standard die set pocket depths
• Spring rate of 146.75 N/mm for predictable, repeatable deflection performance
• Maximum deflection of 22.80 mm with a travel-to-solid load of 586.00 N
• Red color coding allows fast load-class identification during die assembly and changeover
• Manufactured to ISO 10243 standards for dimensional and performance consistency

Compatibility

Designed as a standard replacement or new-build die spring conforming to ISO 10243 specifications, suitable for use in any die set or press tooling application requiring a 16 mm hole diameter, 8 mm rod diameter, and 3-inch free length in the red load class.

Installation Notes

Die springs should be installed by qualified toolmakers or die maintenance technicians following the press or die manufacturer's procedures. Always de-energize and lockout the press before accessing the die set. Do not compress the spring beyond its rated maximum deflection, as operating past the solid height will damage the spring and reduce service life. Inspect springs for fatigue cracks, permanent set, or corrosion at scheduled maintenance intervals.
