A material of the metal area 113 may be metal or metal composite material, the metal may include aluminum, magnesium, stainless steel, titanium and titanium alloys, etc. The filler area 111 is filled by filler, a material of the filler area 111 may be at least one of plastic, ceram, resin, and other organic matters. The filler may be formed by solidifying a filling liquid including fibers, which may speed up the solidifying and improve a combination strength. The fibers include at least one of carbon fibers, glass fibers, and aramid fibers. In at least one embodiment, the filler may include plastic, the plastic may include glass fibers, or the plastic material may be mixed with glass fibers.

Referring to
The recess 34 has a second length. A direction of the second length is parallel to the direction of the first length of the filler area 111 of the first surface 11. The second length is greater than the first length. The groove 33 has a third length. A direction of the third length is parallel to the direction of the first length, the third length is greater than or equal to the first length.
Referring to

When injecting the filling liquid into the recess 34 and an area of the groove 33 corresponding to the recess 34, the injection direction of the filling liquid in the recess 34 is perpendicular to the second surface 31, the arranging direction of the glass fibers is perpendicular to the second surface 31. When injecting the filling liquid into an area of groove 33 non-corresponding to the recess 34, due to a resist of groove bottom 331, the filling liquid is injected in a direction parallel to the second surface 31, thus an arranging direction of the glass fibers is substantially parallel to the second surface 31.
The filler 40 includes a first filling portion 41 in the groove 33 and a second filling portion 43 in the recess 34. Along the direction of the second length, the first filling portion 41 includes opposite ends.

If the second length of the recess 34 is smaller than the first length of the filler area 111, the injecting direction of the filling liquid in the groove 33 is not consistent, thus the arranging direction of the glass fibers in the groove 33 is not consistent, when being cut, which may cause glass fibers fall off and bad appearance of the housing.
Referring to
The metal piece 30 is cut to form the metal area 113 of the first surface 11. A cutting thickness along the second surface 31 is smaller than a thickness of the metal piece 30.

When the cutting thickness along the second surface 31 is greater than or equal to the liner distance between the groove bottom 331 and the second surface 31, due to the third length of the groove 33 is greater than the first length of the filler area 111, at least a part of the first filling portion 41 corresponding to the recess 34 is cut and forms the filler area 111 of the first surface 11. Due to the arranging direction of the glass fibers in the recess 34 and the area of the groove 33 corresponding to the recess 34 is perpendicular to the second surface 31, that is the glass fibers in the recess is arranged in a same direction, thus the glass fibers may not fall off when being cut by a knife, which may prevent glass fibers falling off and a good appearance of the housing.

The groove has a third length. A direction of the third length is parallel to the direction of the first length, the third length is greater than or equal to the first length.
At block S02, injecting filling liquid into the recess and the groove, the filling liquid is solidified to form the filler.
The filling liquid is injected along a side of the metal piece opposite to the second surface to the recess and the groove. The filling liquid includes injection liquid including glass fibers. An arranging direction of the glass fibers is same with the injecting direction (or flow direction) of the filling liquid. When injecting the filling liquid into the recess and an area of the groove corresponding to the recess, the injection direction of the filling liquid in the recess is perpendicular to the second surface, the arranging direction of the glass fibers is perpendicular to the second surface. When injecting the filling liquid into an area of groove non-corresponding to the recess, due to a resist of groove bottom, the filling liquid is injected in a direction parallel to the second surface, thus an arranging direction of the glass fibers is substantially parallel to the second surface.
The filler includes a first filling portion in the groove and a second filling portion in the recess. Along the direction of the second length, the first filling portion includes opposite ends.

When the cutting thickness along the second surface is smaller than a liner distance between the groove bottom and the second surface, due to the second length of the recess is greater than or equal to the first length of the filler area, at least a part of the second filling portion is cut and forms the filler area. When the cutting thickness along the second surface is greater than the liner distance between the groove bottom and the second surface, due to the third length of the groove is greater than or equal to the first length of the filler area, at least a part of the first filling portion corresponding to the recess is cut and forms the filler area of the first surface. Due to the arranging direction of the glass fibers in the recess and the area of the groove corresponding to the recess is perpendicular to the second surface, that is the glass fibers in the recess is arranged in a same direction, thus the glass fibers may not fall off when being cut by a knife, which may prevent glass fibers falling off and a good appearance of the housing is obtained.

In at least one embodiment, the cutting includes cutting the metal piece by a knife, a cutting direction of the knife is perpendicular to the injecting direction of the filling liquid, thus a tangential direction of any point of the first surface formed after cutting is perpendicular to the injecting direction of the filling liquid, which may prevent glass fibers of the filling portions of the first surface falling off.
Selectively, a rotate speed of the knife 50 may be 8000˜12000 r/min. With the rotate speed of the knife 50, a small roughness of the first surface after cutting may be obtained.
The method for processing the housing defines the groove with a length greater than or equal to a length of the filler area of the first surface, injects filling liquid including glass fibers into the recess, thus the arranging direction of the glass fibers in the recess is consistent and perpendicular to the second surface, when cutting the metal piece along the second surface to form the first surface, the glass fibers may not fall off when being cut by the knife, which may prevent glass fibers falling off and a good appearance of the housing is obtained.
