Patent ID: 8075301

Claim:
A suction blowmold, having a cavity formed by two mold halves for producing extrusion suction-blowmolded plastic molded parts using the suction blowmold method, in which an extruded, plastically deformable preform in the form of a plastic melt tube is brought into the closed cavity and into position in the cavity at least partially sliding on a mold surface, the suction blowmold comprising a suction device for introducing the preform into the closed mold halves, wherein at least a part of the mold surface of the cavity has a structuring formed directly into the mold surface, said structuring having an R a value between 0.8 and 6.3 μm and an R z value in the range from 6 to 40 μm and providing a reduced sliding friction to the preform.
