The wheel is monoblock style, the main process has two kinds: First, also known as die forging for the molding segment, through the modelling of hub after forging forming, which can greatly improve the production efficiency, but open to early modeling of investment is relatively high, more suitable for large batch production. Second, processed in advance forging wheel blank for rework operations, through the numerical control machining center (i.e., CNC) milling wheel eventually modelling, the method can reduce the working procedure and time of early prepared. Itself has a lighter weight and better the dynamic balance of performance, so the more lightweight, higher reliability, higher in sealing; At the same time is a higher manufacturing costs, relative to a single simple modeling.
