Abstract
Stampable sheets are molded in compression molding method. The compression molding method has the problem that the glass fiber that stays on surface of molded part effects bad appearance. The transfer molding method is used as molding method of the other plastic materials. In this molding method, the blanks of Stampable sheets flow through the sprue. Therefore, the surface quality and the strength of molded parts differ from compression molding method. In this study, for the purpose of the improvement of the surface quality and the strength of molded parts, the transfer molding method was performed and the effect of molding conditions was investigated experimentally in comparison to compression molding method.
