METHOD OF MANUFACTURING A HOUSING AND DRUM OF WASHING MACHINE

摘要

A method of manufacturing a housing and a drum of a washing machine is provided to improve efficiency of a pressing device by performing a pressing process for plural molds using one pressing device. A method of manufacturing a housing comprises the steps of pressing a workpiece using a first pressing device(10) in such a manner that the workpiece has a predetermined shape, boring the workpiece of the predetermined shape using a second pressing device(20), and bending the workpiece using a third pressing device(30). The first to third pressing devices are sequentially arranged in one direction to continuously perform the pressing work. Transfer units(15,25,35) are arranged among the first to third pressing devices.
