The appearance layer 35 is formed on the outer surface 313 of the base 31. The appearance layer 33 has a thickness of 0.3 to 0.4 mm. The appearance layer 35 is made of a metal material and may be aluminum, aluminum alloy or stainless steel. The appearance layer 35 further includes a protective layer 351 for protecting the appearance layer 35 from being damaged and affecting the appearance of the portable electronic device 100.

The manufacturing method of the housing 30 of the portable electronic device 100 according to the preferred embodiment of the present invention includes the following steps:

A base body 31 is provided. The base body 31 has a basic shape of a casing 30 made of a metal foam material, which may be a foamed aluminum material or a foamed nickel material, and is controlled by a computer numerical control (Computer Number Control, CNC). Formed, the base 31 has a thickness of 0.3 to 0.4 mm.

It can be understood that the base 31 includes an inner surface 311 and an outer surface 313 opposite the inner surface 311.

A metal layer 33 is provided having a basic shape of the housing 30 which is formed by casting and numerically controlled machine tool processing techniques. The metal layer 33 may be made of one of aluminum, aluminum alloy, or stainless steel.

The metal layer 33 is attached to the inner surface 311 of the base 31, and the metal layer 33 is consolidated with the base 31 by welding or adhesive, etc., wherein an anaerobic adhesive is used in the adhesive manner. Epoxy resin, polyurethane glue.

An appearance layer 35 is provided which has the basic shape of the housing 30 and is fabricated by casting and CNC machine tool processing techniques. The appearance layer 35 is made of a metal material. The metal material may be one of aluminum, aluminum alloy or stainless steel.

The surface layer 35 is surface-treated, and a protective layer 351 is formed on the outer surface of the appearance layer 35. Specifically, if the appearance layer 35 is made of aluminum or aluminum alloy, it can be anodized or electrically The protective layer 351 is formed by surface treatment; when the appearance layer 35 is made of stainless steel, it can be processed by physical vapor deposition (PVD), baking varnish or electric painting. The protective layer 351 is formed by surface treatment.

The surface-treated appearance layer 35 is attached to the surface of the substrate 31. Specifically, the surface on which the surface layer 35 is not surface-treated is attached to the outer surface 313 of the substrate 31 by soldering or gluing.
