| 摘要 | 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. | ||

| 主权项 | 1. A process of manufacturing a curved member having a high-grade design surface, comprising the steps of: (1) preparing a sheet having a high-grade design surface and a thickness of 3-6 mm by injection compression molding a resin material containing 90-100 wt % of a polycarbonate resin (step (1)); (2) preheating the sheet at a temperature of (Tg+15)° C. to (Tg+35)° C. (Tg(° C.) is the glass transition temperature of the resin material) to soften it (step (2)); and (3) applying pressure to the softened sheet to curve the high-grade design surface (step (3)). | ||
