Simply stated, the function performed in metal cleaning is removal of material, collected in the previous operations, from the metal's surface to prepare it for subsequent operations. Cleaning metals involves not only the selection of the type(s) of cleaners, but also the proper cleaning cycle and process equipment necessary to generate acceptable parts at a given rate (parts/hour). An equation for such a cleaning operation may be illustrated as follows: Process Equipment + Process Cycle + Cleaner(s) = Acceptable Parts/Hour Each of the terms in the equation shares the burden in providing acceptable parts at a given rate for an economical operation. The equation also notes that in certain operations, more than one cleaner may be required, as per a line for electroplating. Process equipment is the equipment selected—rack line, barrel line, spiral washer, ultrasonic, etc.
