The ASSOCIATED SPRING RAYMOND 204-107 is a heavy-duty die spring engineered for use in stamping dies, injection molds, and other industrial tooling applications. Built from chromium alloy steel with a trapezoidal wire cross-section, it delivers higher load capacity and longer service life compared to standard round-wire springs of the same envelope size. The blue color coding indicates a medium load rating per ISO 10243 standards. It has a free length of 1.75 inches (44 mm), a rod diameter of 5 mm, and a hole diameter of 10 mm, making it suitable for precision tooling fixtures where consistent spring force and repeatable deflection are critical.
This die spring is designed for use in press tooling, die sets, and mold assemblies in manufacturing environments. The ISO 10243 classification and blue color code allow toolmakers and maintenance technicians to quickly identify load class and confirm interchangeability. It is commonly installed in stripper plates, lifters, and ejector assemblies within stamping and plastic injection molding operations. The trapezoidal wire shape maximizes the active material within the spring bore, allowing this compact spring to handle demanding cycle loads.
Designed as an ISO 10243-compliant replacement die spring for industrial press tooling and mold assemblies requiring a medium-load blue-class spring with a 10 mm hole diameter, 5 mm rod diameter, and 44 mm free length.
Die spring replacement is typically performed by tool and die makers or maintenance technicians during scheduled die maintenance or after a spring failure. Always de-energize and lock out the press before accessing the die set. Ensure the rod and hole diameters of the replacement spring match the existing pocket dimensions precisely to prevent lateral loading and premature failure. Do not compress the spring beyond its rated maximum deflection of 16.70 mm to avoid permanent set or breakage.
