Abstract
A suction blowmold () having a cavity () formed by two mold halves () for producing extrusion suction-blowmolded plastic molded parts () using the suction-blowing method, in which an extruded, plastically deformable preform () in the form of a plastic melt tube is brought into the closed cavity () and in position in the cavity at least partially sliding on the mold surface (). The suction blowmold () according to the present invention is characterized in that at least a part of the mold surface () of the cavity () has a structuring which provides a reduced sliding friction to the preform (). A method for producing such a suction blowmold (), the use thereof for producing extrusion suction-blowmolded plastic molded parts (), and corresponding extrusion suction-blowmolded plastic molded parts () are additionally disclosed.
