Problems solved by technology
Since a large number of micropores are also formed on the appearance surface of the metal plate during the T treatment, the cape will penetrate into the micropores on the appearance surface of the metal plate, making it difficult for the plastic infiltrated into the micropores on the appearance surface of the metal plate to be removed. removed, resulting in a poorer appearance of the sheet metal
At present, CNC processing is usually used to remove the edge of the appearance surface of the metal plate, which leads to an increase in the cost of stamping + nano injection molding

The invention provides a preparation method of a shell. The preparation method includes the following steps that a metal part is provided; stamping processing is conducted on the metal part, and at least one through groove is formed in the metal part; surface processing is conducted on the metal part subjected to stamping processing, multiple first micropores are formed in the outer surface of the metal part, and multiple second micropores are formed in the groove walls of the through grooves; the outer surface of the metal part is coated with a water paint layer, and the first micropores are filled with the water paint layer; injection molding processing is conducted on the metal part to form an injection-molded part, the through grooves and the second micropores are filled with the injection-molded part, and the injection-molded part further covers the area, close to the through grooves, of the water paint layer; and the metal part is cleaned so that the portion, close to the area of the through grooves, of the injection-molded part and the water paint layer can be removed. The preparation method of the shell has the beneficial effect of being low in cost, and the shell attractive in appearance can be prepared.
Description
technical field [0001] The invention relates to the technical field of electronic devices, in particular to a housing, a method for preparing the housing and an electronic device using the housing. Background technique [0002] The traditional nano-injection molding process is usually CNC processing + nano-injection molding, which includes the following steps: CNC processing is used to open grooves on the metal plate, and then T-treatment is performed on the metal plate to form micropores on the groove wall. The holes and slots are filled with plastic and the sheet metal is finished again with a CNC process. Since the CNC processing time in the traditional nano-injection molding process exceeds 50 minutes, the cost of the traditional nano-injection molding process is relatively high. Therefore, many manufacturers are trying to replace the expensive CNC+nano-injection method with a low-cost method of stamping + nano-injection molding, that is, forming the appearance surface ...
