Machines
Moreover, beside the continuous copper alloy casting line, there are other machine systems supporting the production, which are vacuum annealing system, surface milling machine, surface pickling and cleaning system, automatic withdrawing machine, sawing machine. Every stage is under careful observation and tests with specialized measure equipment for the best qualified copper alloy strip.
