Abstract: In press moulding or embossing a thermoplastic resin for producing a moulded product excellent in transferability of microscopic surface asperities and having high quality with high productivity, a preform (X-1) of a thermoplastic resin is heated to about the hardening temperature of the thermoplastic resin constituting the preform, the preform is embedded between an upper half (8a) and a lower half (8b) of a mould which are maintained at a temperature of about the hardening temperature of the thermoplastic resin, and then the mould is closed at a low pressure. Carbon dioxide is dissolved in a surface of the preform by charging carbon dioxide through inlet (11) between a surface of the mould and the surface of the preform in order to reduce the viscosity of the preform surface. The surface of the mould is brought into contact with the preform having the reduced surface viscosity by increasing a pressing pressure. Then, carbon dioxide is discharged, and a moulded product is extracted. Thus, the moulded product excellent in transferability of microscopic surface asperities and having high quality can be produced with high productivity.

Abstract: A plasticizing process in which a molten resin that has been plasticized and dissolved in a foaming gas is sent to the front end side of a heating cylinder 20 by means of a screw 21 that rotates in a heating cylinder 20, and the screw 21 retreats according as the molten resin accumulates in the front end side of the heating cylinder 20; a transfer process in which the screw 21 is advanced with rotating and transfers the molten resin accumulated in the front end side of the heating cylinder 20 from a plasticizing unit 2 to an injection unit 3, and an injection process in which the molten resin is injected from the injection unit 3 are conducted and repeated to produce a foamable injection molded product. By this method, in injection molding of a foamable injection molded product dissolved in a foaming gas such as an inert gas, plasticization of a raw material resin and impregnation of a plasticized molten resin with a foaming gas in a molding cycle can be improved, whereby productivity can be improved.
