Hot pressing method for pre-impacted thermal fiber materials

Abstract

The invention relates to a method of hot pressing pre-impregnated thermally treated solid fiber material including the following steps: arranging the mold module (10) to include the first side mold (12) and the second side mold (14); arranging the upper mold (20); attaching the pre-impregnated fiber material (30) to the upper mold with the pre-impregnated fiber material opposite the mold module; closing the upper mold and mold module; heating and pressurizing the upper mold and mold module; Introduce and pour gas (60) with a predetermined pressure (70) through a predetermined conduit (50) into the upper mold to soften the upper mold so that the upper mold is softened and transmits the predetermined pressure of the gas to the pre-impregnated fiber material. Accordingly, the upper mold creates a side pressure on the side wall of the molded product.
