Thermoforming tool for manufacturing of containers of heated plastic foil, particularly bottles, has lower molding chamber section that is formed opposite to upper molding chamber section of molding chamber

摘要

The thermoforming tool has a lower molding chamber section (27) that is formed opposite to an upper molding chamber section (26) of molding chamber in a section plate (18) in each case. A cross section of the molding chamber is larger at a lower surface (24). The cross section of the lower molding chamber section is reduced or constant before an upper surface (25) of a forming device (13) from downward without formation of undercuts at the inner surface of the lower molding chamber section.
