Problems solved by technology

With the continuous upgrading of mobile phones, the mobile phone cover is also innovating at the same time. As the "face" project of the mobile phone, the mobile phone cover plays a special role in it; There are more and more uses on the outer surface of the cover, but the metal cover is mainly formed by CNC machining, which takes a long time and high cost, so mass production is difficult, and metal will cause signal interference and obstruction, so the existing mobile phone The cover is mostly made of plastic or 3D glass. The plastic mobile phone back cover is mostly made of conventional injection molding. Combined with the problem of instability, and its poor toughness, resulting in poor impact resistance; in addition, the thickness of the existing mobile phone back cover is difficult to achieve further ultra-thin, technically limited
[0003] Moreover, the current surface treatment process for the back cover of the mobile phone is relatively simple, so that its appearance effect is relatively limited and the homogeneity is serious. Most of them have a single matte or bright surface effect, which easily causes consumers' aesthetic fatigue. The production process cannot meet the needs of consumers for mobile phone back covers with high toughness, multi-performance and diverse surface effects

Abstract

The invention discloses a production process of a composite board mobile phone rear cover. The production process comprises the following steps of: preparing a composite board substrate, cutting the composite board substrate to obtain a composite board base material, acquiring pattern printing, optical coating, mirror surface silver ink printing, UV transfer glue printing, first color ink layer printing and second color ink layer printing in a printing step, obtaining a semi-finished product of the composite board mobile phone rear cover in a high-pressure forming step, acquiring a hardened film in a step of spraying a strengthening liquid, pasting a film for protection, and conducting CNC cutting machining to obtain the composite board mobile phone rear cover finished product. The composite board material is used for production and processing; a curved surface effect which cannot be achieved by conventional injection molding is achieved; the problem of unstable binding between UV glueand glass in the prior art is solved; the prepared composite board mobile phone rear cover not only achieves the hardness of the glass, but also has the toughness of plastic, can tolerate stronger impact and is ultrathin, and the production process of the composite board mobile phone rear cover is lower in cost and higher in production efficiency.

Description

technical field [0001] The invention relates to the technical field of mobile phone back covers, in particular to a production process for composite board mobile phone back covers. Background technique [0002] Mobile phones have gradually become a necessity in people's daily life. In order to continuously improve user experience and meet market demand, mobile phone R&D and structural designers are gradually improving the mobile phone screen structure, mobile phone appearance, control board, etc. With the continuous upgrading of mobile phones, the mobile phone cover is also innovating at the same time. As the "face" project of the mobile phone, the mobile phone cover plays a special role in it; There are more and more uses on the outer surface of the cover, but the metal cover is mainly formed by CNC machining, which takes a long time and high cost, so mass production is difficult, and metal will cause signal interference and obstruction, so the existing mobile phone The co...
