Abstract

The invention provides method for manufacturing metal casing, which includes steps as follows: (a) stocking a roll of metal plate; (b) extruding a part of metal plate from the roll of metal plate in proper sequence; (c) etching a plurality of holes on the part of metal plate; and (d) forming the part of metal plate to generate metal casing. Step (d) also includes: applying surface process to the part of metal plate; and punch forming the part of metal plate to generate metal casing. Therein, surface process step and punch forming step can be exchanged. The invention also provides a system formanufacturing metal casing, which includes feeder equipment, etching equipment and forming equipment. Metal casing can be manufactured continuously by using the method, and semifinished product management problem in traditional production process can be avoided.

Description

technical field [0001] The invention relates to a method for manufacturing a metal casing, in particular to a method for continuously manufacturing a metal casing by etching a plurality of holes. Background technique [0002] The casings of general devices are mostly made of plastic or metal materials, such as the front frame of a TV. In the case of plastic materials, the front frame of the TV is first injection molded and then painted to complete its surface treatment. Although the processing process is simple, the cost of plastic molds is quite expensive, and large-sized plastic injections are prone to defects such as deformation, distortion, poor filler joints, air bubbles, and holes, resulting in lower product qualification rates and increased costs. In particular, the stability of the plastic at the thin plate structure also seriously affects the injection stability and product quality. [0003] In the case of metal materials, the front frame of the TV is usually stam...
