Associated Spring Raymond 203-616 Die Spring 4 in Green

Product Description

The ASSOCIATED SPRING RAYMOND 203-616 is a heavy-duty die spring designed for use in stamping dies, punch presses, and industrial tooling applications. Built from chromium alloy steel with a trapezoidal wire cross-section, this spring delivers high load capacity in a compact envelope. It carries a free length of 4 inches (102 mm), a rod diameter of 16 mm, and a hole diameter of 32 mm. The green color coding indicates its load classification within the standard die spring color series. Machinists, tool and die makers, and industrial maintenance technicians are the primary installers of this component.

This die spring is suited for use in metal stamping and forming dies where consistent spring force and reliable cycle life are required. The trapezoidal wire profile increases the active material cross-section compared to round wire, allowing higher load ratings within the same dimensional envelope. It is applicable in both OEM die builds and replacement service in existing tooling setups. The spring rate of 182.73 N/mm supports predictable deflection behavior across the operating stroke.

Key Features

• Chromium alloy steel construction for strength and fatigue resistance in high-cycle tooling environments
• Trapezoidal wire shape provides higher load density compared to round wire springs of the same outer diameter
• Green color coding for quick visual identification of load class during tooling setup and maintenance
• Maximum deflection of 41 mm with a corresponding maximum deflection load of 1,312 N
• Manufactured to ISO 10243 standard for die spring dimensional and performance compliance
• Certified under ISO 9001:2008 and ISO/TS 16949:2009 quality management systems

Compatibility

Designed as an ISO 10243 standard die spring replacement suitable for stamping dies and industrial press tooling requiring a 32 mm hole diameter, 16 mm rod diameter, and 4-inch free length in the green load category.

Installation Notes

Die spring installation and replacement should be performed by qualified tool and die technicians or industrial maintenance personnel with the press fully de-energized and all stored energy safely released before disassembly. Verify that the mating hole diameter and guide rod diameter match the spring specifications before installation to prevent binding or premature failure. Do not compress the spring beyond its rated maximum deflection, as exceeding travel-to-solid load limits will reduce service life. Follow applicable machine safety standards and the tooling OEM guidelines when servicing press dies.
