Abstract
A method for manufacturing a metal shell for casing of electronic product comprises stamping, squeezing and milling a sheet metal at a first area and a second area to form hinge side walls. The sheet metal on the periphery is stamped, squeezed, and milled to form side walls. Insert molding is performed at inner surface of the sheet metal to form an internal molded plastic part and a fine machining of the sheet metal is carried out. The metal shell is integrally formed from a single solid sheet, the manufacturing process is simple and economical as CNC processes are reduced.
