Abstract
An electronic device includes an integrally formed metal casing including a first part and a second part that are intersecting with each other. An outer surface of the first part is a first surface presenting a first visual effect. An outer surface of the second part is a second surface presenting a second visual effect. The second visual effect is different from the first visual effect, and the second visual effect is a mirror effect. A boundary line between the second visual effect and the first visual effect is used to distinguish the first surface and the second surface.
Claims9
An electronic device, comprising:
- a metal casing including a first part and a second part intersecting with the first part, the metal casing being made of titanium or magnesium;
- wherein:
- an outer surface of the first part is a first surface presenting a first visual effect;
- an outer surface of the second part is a second surface presenting a second visual effect;
- the second visual effect is different from the first visual effect, the first visual effect is an effect of a protective film of a different color formed on the first surface, and the second visual effect is a mirror effect formed by metal polishing;
- and
- a boundary line between the second visual effect and the first visual effect is used to distinguish the first surface and the second surface.
A fabrication method, comprising:
- obtaining a metal workpiece including a first part and a second part intersecting with the first part;
- performing a first fabrication process on a first surface of the first part of the metal workpiece to form a first visual effect;
- and
- performing a second fabrication process on a second surface of the second part of the metal workpiece to form a second visual effect;
- wherein:
- the second visual effect is different from the first visual effect, and the second visual effect is a mirror effect;
- an outer surface of the first part is the first surface presenting the first visual effect;
- an outer surface of the second part is the second surface presenting the second visual effect;
- a boundary line between the second visual effect and the first visual effect is used to distinguish the first surface and the second surface;
- and
- the second fabrication process at least comprises:
- performing a computer numerical control (CNC) precision machining treatment on the outer surface of the second part to remove a protective layer formed on the outer surface of the second part by an anodic oxidation treatment in the first fabrication process;
- and
- performing a polishing treatment on the outer surface of the second part after the CNC precision machining treatment to form the mirror effect.
