Abstract

PURPOSE: To draw deeply a thermoplastic synthetic resin sheet efficiently while its thickness is prevented from becoming irregular by a method wherein stamping, vacuum and/or pressure forming are combined and conducted in sequence in a solid phase state.
CONSTITUTION: A blank (a resin sheet as a material) 6 which is heated to 0W 10°C below the melting point and is in a solid state is arranged between an upper die (female die) 3 and a lower die (male die) 4, held as a slight slip is allowed between the blank holder 5 of the lower die 4 and the circumferential edge part 17 of the upper die 3 and the upper and the lower die are clamped at a desired depth to stamp the blank 6. Next, the nipping force against the blank 6 is increased by cushion pins 13 and the inner part of the die is sealed and then a vacuum is produced in the upper die 3, pressure is given in the lower die 4 and a half-finished product 14 obtained from the blank 6 is formed in vacuum and/or under pressure to provide a formed part 18.
