Associated Spring Raymond 205-408 Die Spring 2 in Red

Product Description

The ASSOCIATED SPRING RAYMOND 205-408 is a heavy-duty die spring engineered for use in stamping dies, punch presses, and injection mold tooling. Built from chromium alloy steel with a trapezoidal wire profile, it delivers a strong duty rating suitable for demanding cyclic load applications. The spring measures 2 inches (51 mm) in free length and is rated for a maximum deflection load of 316.98 pounds (1410 N) over a maximum deflection of 15 mm. The red color coding identifies its strong duty classification at a glance, consistent with ISO 10243 standards. Licensed die makers, tool and die technicians, and precision machining shops are the primary installers.

This die spring is designed for installation in die sets and mold bases where a 20 mm hole diameter and a 10 mm rod diameter are required. It fits stamping, forming, and progressive die applications in both production shop and maintenance environments. The 15 mm travel to solid load makes it appropriate for operations requiring controlled, repeatable spring return forces within a compact stroke range.

Key Features

• Strong duty rating for high-load cyclic die and mold applications
• Trapezoidal wire cross-section provides higher load capacity relative to round wire designs
• Chromium alloy steel construction for fatigue resistance under repeated compression
• Red color coding per ISO 10243 for quick duty-class identification
• 2 inches (51 mm) free length with 15 mm maximum deflection travel
• Fits 20 mm hole diameter and 10 mm rod diameter tooling

Compatibility

Designed as an OEM-style replacement or direct-fit die spring for stamping dies, punch presses, and injection mold tooling requiring a 20 mm hole diameter, 10 mm rod diameter, and 51 mm free length in the strong duty (red) classification per ISO 10243.

Installation Notes

Die springs are installed by tool and die technicians or qualified machinists. Before replacing a die spring, ensure the press or mold is fully de-energized, de-pressurized, and locked out per applicable safety procedures. Inspect the mating rod and hole dimensions for wear before installing the new spring. Never compress a die spring beyond its rated maximum deflection, as over-compression will reduce service life and may cause failure.
