Abstract

The present invention relates to a mobile phone protection case film with a transparent part and a method for manufacturing the same, and specifically a method for manufacturing a protection case film inserted in a protection case cover hinged to one side of a protection case for receiving the back and the sides of a mobile phone so as to open or close the front of the mobile phone, includes the steps of: assembling a first die and a second die so as to form a cavity conforming with the shape of the protection case film; filling the cavity with a molten resin through a gate provided in one side of the cavity; compressing the molten resin filling the cavity by closely contacting the first die and the second die with each other; cooling or hardening the molten resin; removing the molded product by separating the first die and the second die; and cutting off the gate from the molded product. Thus, the method can considerably reduce the processing time and cost compared to the conventional processing method using a numerically controlled processing machine, and minimize the flaw rate by eliminating the errors according to the skill of a worker so as to improve the reliability of the product.
