[Prior Art] The front case of an electronic device generally has a base body and a display window. In the manufacturing industry of conventional rigid shells, the substrate and the display are separately formed separately, and then the substrate and the display window are combined into a front shell by ultrasonic welding, hot-melt welding, double-sided tape bonding or other joining methods. Before the method is manufactured, the gap between the substrate and the display window is prone to occur, the bonding quality is unstable, and the production efficiency is not high. At present, the industry also has a method of burying the substrate and the display window by molding technology. The method mainly involves first placing the display window in the mold, and then combining the plastic with the display window by injection molding plastic to form An integral housing in which the injected plastic forms the substrate. This method avoids the occurrence of a gap between the substrate and the display window. However, in this method, the display window is first formed and then the display window is formed into a plastic body, and the production efficiency is not high. In addition, the industry has also emerged that a two-shot molding technique is to form a housing having a display window at a time by sequentially or simultaneously injecting a substrate and a display window material. The method improves the production efficiency of the manufacturing shell, and the shell formed by the technology has a rough surface and a smooth surface of the display window, and is not smooth due to the nature of the base material and the display window material, such as shrinkage of the material. The ratio of the casing obtained by the method is such that the display window is prone to pleats. 200909178.
