Abstract

The invention relates to the technical field of portable electronic product housings, and discloses a method for manufacturing a narrow frame housing, a narrow frame housing, and a mould. The method for manufacturing the narrow frame housing is used to form a face shell on screen glass by injection molding. A mould is provided. The screen glass is fixed in the mould. The outer side wall of the screen glass and the outer edge of the rear end face are exposed to an injection molding channel. The mould is connected with an injection molding machine. The injection molding machine injects colloid to the injection molding channel of the mould, so that the colloid covers the outer side surface of the screen glass and the outer edge of the rear end face, thereby forming the face shell connected with the screen glass. The face shell and the screen glass are combined to form the narrow frame housing. After the colloid is solidified, the narrow frame housing is taken out from the mould. The screen glass of the narrow frame housing is directly fixed on the face shell through injection molding, so that the screen glass and a plastic housing form integrally. Adhering objects are not needed. On the premise that the screen glass is fixed, the area of a support region on the face shell is reduced, thereby achieving effect of a narrow frame and increasing visual area of the screen.

Description

technical field [0001] The invention relates to the technical field of casings of portable electronic products, in particular to a casing with a narrow frame, a manufacturing method thereof, and a manufacturing mold. Background technique [0002] It is a development trend that the screens of portable electronic products such as tablets and mobile phones become larger, and the technology of electronic inner screens is relatively mature and can be made into various sizes. How to increase the viewing area of ​​the screen without increasing the size of the product has become an important technical research direction. [0003] Since the outer screen, that is, the installation method of the screen glass is to apply glue around the screen glass and then paste it on the cover, affected by the size of the cover, a part of the cover must be reserved to support the screen glass. Without enlarging the volume of the panel, if you want to obtain a larger viewing area of ​​the screen, you...
