PCT No. PCT/JP95/02405 Sec. 371 Date May 28, 1997 Sec. 102(e) Date May 28, 1997 PCT Filed Nov. 27, 1995 PCT Pub. No. WO96/16785 PCT Pub. Date Jun. 6, 1996The present invention is an injection compression molding method and apparatus therefor which are capable of using a simple structure for rapidly molding a multilayer molded product with high strength and high accuracy. A molding method for attaining such characteristics includes the steps of extending an injected molten resin (51) by compressing the same in metal molds (31, 32), opening the metal molds during or after the extending operation, injecting a surface layer material (60) into a cap ( delta ) occurring between the metal molds (31, 32) and the molded resin (51) when the molds are opened, closing the molds during or after the injecting of the surface layer material (60), and cooling the resin (51) and the surface layer material (60) in the closed metal molds (31, 32).
