Publication number: 20130257241Abstract: A method for manufacturing a case frame is provided in which a real material is simulated by the manufacturing process from both an appearance and a texture (feel). In the method, a case frame is formed in a shape corresponding to an applied product. A first paint layer is formed using color of a material applied to a surface of the formed case frame. A pattern print layer corresponding to a texture pattern of a relevant material is formed on an upper portion of the first paint layer. A second paint layer is formed such that the first paint layer and a pattern of the pattern print layer are properly expressed that their texture simulates a relevant material. The pattern print layer is further additionally formed on an upper portion of the first paint layer, so that texture of the relevant material can be simulated more realistically.Type: ApplicationFiled: March 18, 2013Publication date: October 3, 2013Applicant: SAMSUNG ELECTRONICS CO., LTD.Inventors: Chang-Youn HWANG, Seng-Ho AHN, Pil-Woo LEE
