ABSTRACT:
A heater core is freed of solder and flux contaminants produced during its manufacture by burnishing the exposed surfaces of the heater core by a wet blasting operation with a slurry of abrasive particles. The burnishing of the cores is achieved in a continuous operation in which the heater cores are advanced in succession through a housing from a loading station to an unloading station. In the housing, the heater cores are burnished with jets of slurry from nozzles after which the heater cores are rinsed with water. The slurry is recycled and maintained at a particular concentration and pH for uniform treatment of the successive heater cores.
