Metal shell of electronic product and manufacturing method of metal shell

Abstract

The invention relates to the technical field of material processing, in particular to a metal shell of an electronic product and a manufacturing method of the metal shell. The manufacturing method of the metal shell comprises the following steps of material preparation, shell forming, roughening treatment, injection molding and finished product shaping. The roughening treatment step includes the procedure of pretreatment, the procedure of anodic oxidation film forming treatment and the procedure of roughening liquid treatment. According to the manufacturing method, the process is simple, machining difficulty can be lowered, machining efficiency can be improved, the application range is wide, and the manufactured metal shell of the electronic product has both the advantages of metal materials and the advantages of plastic materials and effectively overcomes the defects of the metal materials and the defects of the plastic materials; the manufactured metal shell of the electronic product has the advantages of being low in weight, high in strength, good in electrical performance and good in heat-conducting property.

Description

technical field [0001] The invention relates to the technical field of material processing, in particular to a metal shell of an electronic product and a manufacturing method thereof. Background technique [0002] In the prior art, in the fields of mobile communication equipment, electronic and electrical equipment, automobile machinery, etc., it is often necessary to spray, bond, and inject the metal surface. In order to improve the bonding strength of surface attachments, it is usually necessary to treat the surface, such as Common treatment methods such as phosphating, passivation, making holes, and undercuts, in short, all improve the bonding strength of metals and attachments by increasing surface corrosion resistance and roughness. [0003] The traditional method is to use phosphating and passivation to corrode the metal surface by soaking in chemical solution to achieve the purpose of not only protecting the metal surface but also roughening the surface to improve the...

Problems solved by technology

[0003] The traditional method is to use phosphating and passivation to corrode the metal surface by soaking in chemical solution, so as to not only protect the metal surface but also roughen the surface to improve the bonding strength of the metal and the attachment. The rough surface obtained by this method is uneven and irregular, and is only suitable for relatively rough and simple protection. The bond strength of the surface attachment of the treated metal is low. There are many types of conventional methods for making micropores to roughen the surface. For example, Chinese patents CN102537066A, CN102145331A, CN1584119A, CN101578018A, etc. propose methods such as laser micromachining, assembly coating, and design of rounded corners and undercut embedding, all of which talk about methods of improving the bonding strength of metal surfaces and attachments from various angles. However, these methods have various problems such as complex operation, high cost, and narrow application to varying degrees, which limit their application to a certain extent.
