    Abstract: A process for producing polylactic acid resin foam particles for in-mold foam forming from which a polylactic acid resin foam molding excelling in heat resistance and mechanical strength can be obtained by in-mold foam forming. In the process for producing polylactic acid resin foam particles for in-mold foam forming, a rotary blade is rotated at a given rotational frequency while constantly keeping contact with the anterior edge surface of a nozzle mold, and the polylactic acid resin extrudate having undergone extrusion foaming from the nozzle mold and foaming is cut by the rotary blade. Accordingly, the polylactic acid resin extrudate can be securely cut to thereby obtain approximately spherical polylactic acid resin foam particles. Therefore, when the polylactic acid resin foam particles are used in in-mold foam forming, foaming of the polylactic acid resin foam particles occurs substantially uniformly in all directions, so that there can be realized mutual strong thermal fusion bonding integration of foam particles in all directions.

    Abstract: PURPOSE: A preparation method of foam product is useful for manufacturing high quality foam product with low production cost by using only one foam resin material in various metallic molds for casting the foam product. CONSTITUTION: A preparation method of foam product starts by a first step of obtaining a number of foam resin solid pieces formed below the foaming temperature. In a next step, the solid pieces are provided into a foam cavity. In a third step, by using a heater, the inner side of the cavity should be heated to reach a temperature above the foam temperature and maintain it for a certain time. Finally, the metallic mold is opened and the final foam product is obtained. The solid piece can be pellet type or flake type materials by forming the foam resin into elongated bar and cutting it to any desired size.
