Abstract

The invention relates to a shell manufacturing method, which comprises the following steps: firstly, forming a plastic molding structure (plastic materials such as fibers, mud and ceramic) on a mold; secondly, drying the plastic molding structure by using a drying device; thirdly, removing the mold to get the plastic molding structure in the mold; fourthly, spraying a first metal body on the plastic molding structure in a meltallizing manner; and finally, after the molding of the first metal body, spraying a second metal body on the molded first metal body in the meltallizing manner to obtain the finished shell, wherein the melting point of the second metal body is higher than the melting point of the first metal body. When the shell manufacturing method is used, the common complex metal shell manufacturing method is simplified, the metal shell manufacturing efficiency is improved, the cost of the metal shell is greatly reduced, and the shell is thinned.

Description

technical field [0001] The invention relates to a method for manufacturing a shell, in particular to a method for manufacturing a shell by successively spraying low-melting-point and high-melting-point metals on a formed plastic structure to form the shell. Background technique [0002] The shells of general electronic devices are mostly made of metal materials. In the manufacturing process, there must be different procedures such as shell forming, stamping, polishing, and welding. Because the manufacturing process requires more complicated methods, it often costs a lot of money. It takes less time, and the integrated metal shell is directly made of expensive materials such as metal or alloy, resulting in a generally high unit price of electronic devices, which cannot reduce the cost, thus destroying the precious resources of nature. Especially under the current trend of simple process and cost reduction, it is necessary to design a casing that can be produced quickly and at...
