Plastic back cover is manufactured by the injection molding process. During the injection molding process, corresponding molds are made according to the design dimensions and shape of the back cover. The molten plastic material is injected into the mold cavity, and after cooling and solidification, the basic shape of the back cover is formed. Then, according to the appearance requirements of the product, surface treatment is carried out on the back cover to obtain the desired color, luster and decorative effect.
