A condition setting calculation device (104) compares an actual value of the material characteristic received via a network (105) from a material characteristic data providing device (101) to a standard value and corrects the molding conditions such as a molding speed and a wrinkle flattening pressure according to the comparison result. A control device (300) controls a press molding device (102) so as to start press working of a material-to-be- pressed (300) with the corrected molding condition. Thus, it is possible to minimize generation of cracks and wrinkles when pressing the material-to-be- pressed (300) and obtain products of substantially identical shape.

La présente invention décrit un dispositif de calcul de réglage de condition (104) comparant une valeur réelle de la caractéristique de matériau reçue par l~intermédiaire d~un réseau (105) à partir d~un dispositif de distribution de données de caractéristiques de matériau (101) à une valeur standard et corrigeant les conditions de moulage telles qu~une vitesse de moulage et une pression d~aplanissement de plis selon le résultat de comparaison. L~invention décrit également un dispositif de commande (300) commandant un dispositif de moulage par presse (102) afin de démarrer le travail de presse d~un matériau à presser (300) avec la condition de moulage corrigée. Ainsi, il est possible de minimiser la génération de fissures et de plis lors de la presse du matériau à presser (300) et d~obtenir des produits de forme pratiquement identique.
