Problems solved by technology

However, the metal die-casting process is easy to form pores and material lines on the surface of the metal shell. Due to the limitation of the metal surface treatment process, it cannot be directly anodized, electroplated, etc., which greatly limits the appearance of the metal shell.

Abstract

The invention provides a casing manufacturing method. The method comprises steps as follows: metal sheets are provided and machined to form an outer frame, wherein the outer frame comprises a peripheral side wall and an accommodating tank defined by the peripheral side wall; a middle frame is formed through mould forming and comprises an outer side wall; the middle frame is mounted in the accommodating tank, and the outer side wall and part of the inner surface of the peripheral side wall are fixedly connected through welding; a gap is formed in the part between the middle frame and the peripheral side wall; plastic filling is performed, and a filling area comprises the gap between the middle frame and the peripheral side wall; secondary machining is performed on size and appearance of the outer frame; the outer surface of the outer frame is subjected to surface treatment. The invention further provides an electronic device.

Description

technical field [0001] The invention relates to the field of shell processing, in particular to a shell manufacturing method for an electronic device, the shell and the electronic device. Background technique [0002] At present, metal casings of electronic devices such as mobile phones and computers are generally made of aluminum profiles or stainless steel to meet high-quality appearance requirements. During the manufacturing process, the metal shell is processed by a CNC machine tool (Computer numerical control, CNC) to form a basic structure, that is, a complete profile is processed by a CNC for multiple times. This processing method usually has disadvantages such as long processing cycle, waste of raw materials, high defect rate, large demand for equipment, and high processing cost. [0003] For the problems existing in CNC machining, it can be solved by metal die-casting process. The metal die-casting process directly uses molds to form metal shells made of aluminum / ...
