Casting noise-damped, vented brake rotors with embedded inserts

摘要

An assembly of like two rib cores enclosing a splitter core are used to carry two or four sound damping inserts for sand mold casting of a pair of vented and damped brake rotors. Sand mold bodies are configured to define outboard surfaces of hub and rotor surfaces of the cast brake rotors. The three-piece core assembly is shaped to define the complex inner surfaces in casting of vented rotor bodies carrying one or two annular sound damping inserts.
