摘要： A method for blow molding a superplastic metal plate by in relation to time applying to it pneumatic pressure that is based on a maximum value of a strain rate of the superplastic metal plate as a set pattern of pneumatic pressure in relation to time when the metal plate is subjected to a high-speed blow molding after being heated to a desired temperature, comprising the steps of: entering data on a shape into which the metal sheet is to be blow molded and on properties of a material of the metal plate to store the data in a storage; determining a set pattern of a pneumatic pressure in relation to time from the entered data on the shape and the properties of the metal sheet; dividing the set pattern of the pneumatic pressure into an appropriate number of parts in relation to time; determining the values of parameters for controlling the pneumatic pressure for each part divided from the set pattern of the pneumatic pressure; and controlling the pattern of the pneumatic pressure using the determined values of the parameters for controlling the pneumatic pressure.
