  • Process of manufacturing a curved member having a high-grade design surface and member manufactured by the process
    Patent number: 9296143
    Abstract: It is an object of the present invention to provide a process capable of manufacturing various types of curved members having a high-grade design surface which are used as glazing members for means of transport such as automobiles at a low cost. The present invention is the process of manufacturing a curved member having a high-grade design surface, comprises the steps of: (1) preparing a sheet having a high-grade design surface by injection compression molding a resin material containing a thermoplastic resin; (2) preheating the sheet at a temperature of (Tg+5)° C. to (Tg+70)° C. (Tg(° C.) is the glass transition temperature of the resin material) to soften it; and (3) applying pressure to the softened sheet to curve the high-grade design surface.
