The invention discloses a production method of a mobile phone shell, and relates to the field of production of shells of electronic products. The method comprises the following steps: 1, preparing thefollowing raw materials: 44.5-55% of polyester polyol, 29-41% of diisocyanate, 10-19% of a chain extender, 0.1-0.6% of a lubricant, 0.01-0.03% of a catalyst, 0.5-1% of phosphor and 0.25-0.5% of a dye; 2, mixing all heated raw material components, and injecting the obtained mixture into a double screw reactor; 3, ejecting the plasticized raw materials from a nozzle, allowing the raw materials to enter a mobile phone shell die, and molding the raw materials; 4, sequentially spraying a primer and a colored paint on the molded mobile phone shell, and carrying out vacuum coating; 5, carrying out laser engraving to remove a vacuum coated film in an area to be displayed of a colored paint layer; and 6, sequentially forming an intermediate paint layer and a UV finish layer on the surface of the vacuum coated film. The mobile phone shell can reflect abundant colors and qualitative sense effects, can reduce the cost, and also can achieve an expected appearance visual sense effect in order to meet people's customized demands.
