Alliance provided the customer an Aquamaster CC-1800X indexing conveyorized parts cleaning system.  The machine included wash and blowoff process zones.  Heavy-duty stainless steel part fixtures located on 42″ centers were provided to hold one (1) engine block per fixture.  A servo-controlled indexing conveyor equipped for automated part loading and unloading by pick-and-place was provided.  Pneumatically actuated spray and blowoff manifolds positioned above designated fixture stop locations are lowered for cleaning and blowing off leading and trailing engine block surfaces.
