The present invention relates to a method for manufacturing a mobile phone protective case, and more particularly, by providing an adsorption means for adsorbing and fixing a film material on a mold surface during a thermal forming operation, thereby preventing a mobile molded product from being lifted or deformed. And it relates to a mobile phone protective case manufactured through this.

In general, people who want to communicate or call use a variety of communication means. Such means of communication include wired telephones, computers, mobile phones, and the like. Recently, due to its portability and convenience, most people are using mobile phones widely.

In recent years, such a mobile phone has been added with the functions of a media player digital camera and a digital storage device in addition to a telephone function, and thus, an expensive mobile phone has been released, and users want to protect the appearance of the mobile phone from scratches or external shocks.

Accordingly, various mobile phone protection cases are sold to protect the appearance of mobile phone devices, and the mobile phone protection cases may be classified into soft cases made of vinyl or artificial leather, and hard cases made of plastic.

By the way, the soft case made of vinyl or artificial leather as described above is close to the mobile phone to protect the mobile phone against shocks, but when water enters the inside, it cannot be discharged to the outside, causing moisture to enter the mobile phone and thereby causing device failure There is this.

Accordingly, in recent years, hard cases using PC (Polycarbonate) or ABS (Acrylonitrile Butadien Stryrene) have been widely used.
