The invention relates to a method for producing a container () from a thermoplastic, having at least one surround (), provided in the container wall (), for a container opening. The surround () comprises a structure behind which parts of the container wall () extend and/or which is penetrated by said parts. The method is carried out using a multi-part blow mold that has at least two mold parts, each having at least one cavity, wherein the surround is placed as an insert in the cavity () of the blow mold (). The method comprises pressing the preform that has been forced into the cavity () into the structure of the surround () by means of a tool which is brought to bear on the preform () on the side of the preform facing away from the cavity ().

Method for producing a container from a thermoplastic

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.
