Problems solved by technology

[0002] At present, the bottom cover of mobile phones on the market includes plastic parts (plastic parts) and metal parts (metal parts). Due to the imperfect treatment process of the bottom surface of the bottom cover, there is a gap between the plastic part and the stainless steel part after grinding (the surface of the plastic part is lower than the stainless steel part) parts surface), the surface of stainless steel parts is wrinkled, which makes the efficiency of the bottom cover low in mass production and the quality is difficult to guarantee

Abstract

The invention provides a bottom cover, a making method of the bottom cover and a mobile phone. The making method of the bottom cover comprises the steps that the surface of the bottom cover is roughlypolished; the surface, subject to rough polishing, of the bottom cover is subject to median polishing treatment; the surface, subject to median polishing treatment, of the bottom cover is subject tofine polishing treatment. According to the making method of the bottom cover, the surface of the bottom cover is subject to rough polishing, scratches and dirt on the surface of a plastic part and thesurface of a stainless steel part can be removed, the surface of the bottom cover is subject to median polishing treatment, the plastic part and the stainless steel part are rubbed down, the surfaceof the plastic part and the surface of the stainless steel part are flat, the segment gap does not exist between the plastic part and the stainless steel part, no wrinkling exists on the surface of the stainless steel part, the surface of the bottom cover is subject to fine polishing after median polishing, luster on the surface of the plastic part and the luster on the surface of the stainless steel part are increased, comprehensive flows of rough polishing, median polishing and fine polishing are sequentially carried out, and therefore no gap segment exists between the plastic part and the stainless steel part on the surface of the bottom cover, and the surface of the stainless steel part is not wrinkled.

Description

technical field [0001] The invention relates to the field of mobile phones, and more specifically, to a method for making a bottom cover, a bottom cover made by the method, and a mobile phone including the bottom cover. Background technique [0002] At present, the bottom cover of mobile phones on the market includes plastic parts (plastic parts) and metal parts (metal parts). Due to the imperfect treatment process of the bottom surface of the bottom cover, there is a gap between the plastic part and the stainless steel part after grinding (the surface of the plastic part is lower than the stainless steel part) The surface of the parts), the surface of the stainless steel part is wrinkled, which makes the efficiency of the bottom cover in mass production low and the quality difficult to guarantee. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. [0004] Therefore, the purpose of the f...
