Document Type and Number:
WIPO Patent Application WO/2011/049186
Kind Code:
A1
Abstract:
Provided is a method for producing a wide variety of curved members having high quality design surfaces, at a low cost, the member being used in a grazing member for a transportation machine such as an automobile.
The method for producing a curved member having a high quality design surface comprises the following steps: (1) preparing a sheet having the high quality design surface, the sheet being formed by injection compression molding of a resin material containing a thermoplastic resin; (2) preheating and softening the sheet at a temperature range of (Tg+5) to (Tg+70)°C where Tg (°C) represents a glass-transition temperature of the resin material; and (3) bending the high quality design surface by exerting pressure on the softened sheet.
