Abstract
The invention refers to a method for the production of hollow bodies from thermoplastic, in particular for the production of motor vehicle tanks, in which the plastic is shaped as an extruded preform in the still plastic state or as a semi-finished product into at least two shells with the aid of at least one molding die (), with the use of heat, and the subsequently cooled and then dimensionally stable shells are placed one on the other and joined together into an essentially closed hollow body. As molding die () is used at least one positive die which has essentially the contour of the shells. The shells are shaped by the plastic being laid against the positive die. The apparatus for carrying out the method is also disclosed.
