Abstract
PURPOSE: To form a vessel having a uniform wall thickness, in a resin scrapless forming method with pressurized air, by attaching a plug to a cover and forming a cavity in a forming die and the upper portion of a lower ring.
CONSTITUTION: A heated synthetic resin sheet cut piece is rolled between upper and lower platens 12, 14 and upper and lower rings 16, 18 into a rolled sheet 10 having a reversed tray-shape. Thereafter, the upper and lower platens 12, 14 are removed, and the upper ring 16 is then closed with a cover 52, while the lower ring 18 is closed with a forming die 54. In this state, the rolled sheet 10 is formed with pressurized air. In this device, a metal (brass, copper or the like) plug 53 whose lower end is formed into a curved projecting plane is attached to the center of the under surface of the cover 52, while a cavity 68 depressing through a forming plane into the forming die 54 and the upper portion of the lower ring 18 is formed.
