Publication number: 20120018914Abstract: Provided is a sheet press molding method that can create molded articles having low thickness deviation. In this method, a molded article (30) is formed by applying pressure to a sheet material (20) using a pair of dies (10), at least one of which has a prescribed recess-projection pattern (13) comprising recess and projection portions. The method includes: a sheet-forming process in which a recessed portion (2a) having volume equal to the total volume of the projection is formed in the surface of the sheet material (20), which includes a resin composite and 60-95% filler by volume; and a pressing process wherein the recessed portion (2a) in the sheet material (20) is placed facing the recess-projection pattern (13) on the dies (10) and pressure is applied to the dies (10), thereby forming a molded article (30) to which the recess-projection pattern (13) is transferred.Type: ApplicationFiled: March 16, 2010Publication date: January 26, 2012Applicant: SHOWA DENKO K.K.Inventors: Tomoya Utashiro, Yoshinori Ito, Masayuki Noguchi
