Associated Spring Raymond 203-314 Die Spring 3.5 in Green

Product Description

The ASSOCIATED SPRING RAYMOND 203-314 is a heavy-duty die spring engineered for use in stamping dies, molds, and industrial tooling applications. Constructed from chromium alloy steel with a trapezoidal wire profile, this spring delivers controlled force and consistent deflection under repetitive load cycles. The green color code identifies its load rating within the standard ISO 10243 classification system. With a free length of 3.5 inches (89 mm) and a maximum deflection of 36.5 mm, it provides predictable performance in precision tooling environments. Installation and replacement are handled by toolmakers, die setters, and industrial maintenance technicians.

This die spring is suited for use in stamping dies, injection molds, progressive dies, and similar industrial tooling where controlled spring force is required. The green designation indicates a medium-heavy load range per ISO 10243 standards. It fits into tooling bores designed for a 16 mm hole diameter and is guided by an 8 mm rod diameter. Typical applications include stripping, pressure pads, and lifters in metal fabrication and plastics tooling setups.

Key Features

• Chromium alloy steel construction for durability under high-cycle fatigue conditions
• Trapezoidal wire cross-section maximizes material density and energy storage per unit length
• Green color coding follows ISO 10243 classification for consistent load identification
• Maximum deflection load of 313.90 N with 36.5 mm travel to solid load
• Spring rate of 49.11 N/mm for predictable force output throughout deflection range
• Manufactured under ISO 9001:2008 and ISO/TS 16949:2009 certified quality systems

Compatibility

Designed as an ISO 10243 standard die spring for industrial tooling bores requiring a 16 mm hole diameter and 8 mm rod diameter guidance, with a 3.5-inch free length.

Installation Notes

Die springs should be installed by qualified toolmakers or die setters with the mold or die in a safe, de-energized state and press locked out per LOTO procedures. Ensure the guiding rod and bore dimensions match the spring specifications before installation. Do not compress the spring beyond its rated maximum deflection of 36.5 mm, as exceeding travel-to-solid load will damage the spring and reduce service life. Inspect mating surfaces for burrs or misalignment that could cause uneven loading.
