Embodiment 1

[0020] Such as figure 1 As shown, the shell polishing and shaping method of the present invention includes the following steps:

[0021] S101. Use a hot air gun to heat the bad appearance of the shell; the bad appearance of the shell includes bumps, dents and gaps on the shell. Preferably, use the nozzle of a hot air gun to blow hot air for 3 to 5 seconds on the poor appearance of the shell. The temperature of the hot gas is 230±10°C. The housing is reinforced polycarbonate plastic containing 10% glass fibers.

[0022] S102. Use 1000-mesh grinding and polishing to finely grind the parts with poor appearance of the shell.

[0023] S103. Use a 7000-mesh grinding and polishing wipe to polish the parts with poor appearance of the shell.

[0024] The mesh refers to the number of points that can be accommodated in a size of 1 square centimeter. Such as sandpaper (abrasive cloth), gauze, etc., the density is calculated in "mesh".

[0025] S104. Check whether the appearance of t...

Embodiment 2

[0034] The present invention also provides a shell, which is a matte material shell, which is repaired by the aforementioned shell polishing and shaping method.

Embodiment 3

[0036] The present invention also provides an electronic product, which is repaired by the aforementioned casing polishing and shaping method.

Abstract

The invention provides a shell polishing and shaping method, a shell and an electronic product, and the method comprises the following steps: heating a poor-appearance part of the shell through a hotair blow gun; performing fine grinding on the poor appearance of the shell; polishing the poor appearance part of the shell; and checking whether the appearance of the shell polishing and shaping partis qualified. According to the shell polishing and shaping method, the appearance yield of the electronic product shell can be effectively improved, the utilization rate of the shell can be greatly increased, and the production cost is saved.

Description

technical field [0001] The invention relates to the field of electronic product production and manufacturing, a method for repairing bruises, dents and gaps, polishing and reshaping of matte material housings, and the housing and electronic products repaired by the method. Background technique [0002] In the existing mobile phone / tablet manufacturing process, after the PC+10% GF shell is damaged by bumps or dents, the appearance cannot pass the inspection standard, and it can only be scrapped, resulting in waste of production and manufacturing. Through this method, the PC+10% The matte casing made of %GF material is restored to a normal appearance through systematic polishing and shaping methods. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a shell polishing and shaping method, which can improve the appearance yield of the mobile phone / tablet shell, improve the utilization rate of the shell, and save producti...
