The female die has a grain pattern on an inner surface thereof and a plurality of minute holes extending therethrough. The method further includes closing the male die and the female die to press the sheet against the inner surface of the female die, drawing the sheet to the female die by vacuum pressure through the plurality of minute holes, and thereby the grain pattern on the female die is transferred to the sheet. After that, thermoplastic molten plastic material is injected into a space between the laminate material and the male die, and is cooled down so that the plastic product is formed by integrating the sheet and the injected material.
