Abstract

PURPOSE: To form a detailed configuration on the heat-treated sheet economically by a method wherein a whole configuration is formed on the plastic sheet by a heating die, subsequently, the sheet is formed by a cooling die having the whole configuration corresponding to the heating die and the predetermined detailed configuration.
CONSTITUTION: The heated plastic sheet 1 is put on the upper surface of a pressure chamber 5 and the heating die 2 is lowered to secure the sheet 1, thereafter, pressurized air is blown from the pressure chamber 5 side to provide the sheet 1 with the whole configuration formed on the heating die 1. A form, thus obtained, is maintained in a condition as it is to heat-treat it for a predetermined period of time, thereafter, the cooling die 3, havig the whole configuration corresponding to the heating die 2 and the predetermined detail configuration 6, is elevated and the form is formed with the final configuration by blowing pressurized air from the heating die 2 side so as to form it along the cooling die 3 and cool it also. According to this method, the detailed configuration may be formed on the heat-treated sheet economically.
