Manufacturing FG300 cast iron rotors for automotive applications involves initial prototype creation via CAD and rapid prototyping, followed by rigorous testing. Material selection prioritizes FG300 for its thermal conductivity and wear resistance. Tooling design ensures casting consistency, as molten FG300 is poured into molds, cooled, and solidified. Finishing operations refine dimensions and surface quality. Stringent quality control throughout guarantees compliance. Batch production replicates the process for multiple units. Testing verifies performance and durability.
