Problems solved by technology

However, in this method, the existing material injection molding requires skilled technicians to adjust the heater of the barrel according to the needs in real time on site, and manually control the size of the cooling water in the cooling mechanism, which wastes manpower and cost, and makes the heating temperature of the material If the adjustment is not timely, the heating temperature will be too high, which will affect the quality and finished products, or the defective products will appear due to insufficient heating temperature.

Abstract

The invention discloses a mobile phone case with the metal texture. The mobile phone case is prepared from the following raw materials in parts by mass: 30 to 50 parts of thermoplastic starch, 5 to 15parts of lignin, 5 to 22 parts of ethylene and acrylic acid copolymers, 3 to 15 parts of polyvinyl alcohol, 40 to 50 parts of photo-curing materials, 3 to 6 parts of photosencitizers, 15 to 25 partsof activated monomers, 5 to 15 parts of auxiliary agents, 3 to 6 parts of Mg, 2 to 4 parts of Si, 1 to 3 parts of Co and 3 to 5 parts of Al. The vacuum non-conductive electric plating and 3D printingtechnology are combined; arithmetical operation is performed through building a primary model; the optimum mobile phone case parameter is obtained; the plastic processing temperature and water quantity can be automatically controlled; the manual operation is not needed; the production efficiency is improved; the quality of a manufactured finished product is high.

Description

Technical field [0001] The invention belongs to the technical field of communication equipment, and specifically relates to a mobile phone case with a metallic texture and a preparation method thereof. Background technique [0002] From the initial first battlefield mobile phone to the current 4G smartphone, extending to the upcoming 5G era, the functions of mobile phones are becoming more and more powerful. The mobile phone case started from the initial plastic, and now the plastic, glass, metal and other materials coexist. The diversification of mobile phone cases meets the needs of different customers. [0003] As the raw material of mobile phone cases, plastic has the advantages of low cost, ease of use and high plasticity, and the technology is mature, but its thermal conductivity is low, the texture is not good, and it is difficult to upgrade; glass has a delicate appearance, crystal clear, but glass is fragile, The high cost of after-sales and maintenance makes it difficult...
