Glass covering film manufacturing method

The invention discloses a glass covering film manufacturing method which comprises the following steps: injecting liquid silica gel with the formed thickness being 0.2mm into a mold, putting a glass sheet in the mold, wherein the surface, to be subjected to film covering, of the glass sheet faces the liquid silica gel, pressing tightly the glass sheet by a pressing plate, and positioning; baking at 80-150 DEG C for 20-30min; and after forming, putting a silica gel film and the glass sheet out of the mold. The mold is simple in structure and easy to operate, and avoids problems, such as unsmooth gas discharging, and swelling and bubbling of plastic pieces, probably existing in a traditional injection mold; the thickness of the silica gel film is 0.2mm only; glass is used as a part in the forming process, is formed integrally with the silica gel film and then is demolded with the silica gel film together; the problems, such as mold sticking and piece damage, probably existing in the demolding process of the traditional injection mold are solved, and the problem that the assembling of a thin film with the thickness being 0.2mm is difficult is also solved.
