Abstract: A method for producing a plastic article includes extruding an approximately tubular blank from an extrudate and shaping the blank into a hollow body inside a blow-mold using differential pressure, wherein at least one insertable part is introduced into the interior of the partially molded plastic article before the latter is fully shaped into a finished plastic article, and the tubular blank is arranged between at least two halves of a blow-mold by means of an intermediate frame.

Abstract: A blow-molding machine for producing blow-molded hollow bodies from a thermoplastic material, includes two blow-mold halves which can be horizontally displaced and provided with separate drive units for a transport drive and for the sequence of movements of the mold closing and locking device to open and close the blow mold halves. Conventional blow-molding machines are still equipped with hydraulic drives at least for the mold closing and locking device. In order to provide a blow-molding machine that can for example be operated under clean-room conditions, the drive unit of the blow-molding machine according to the invention is configured for the clamping elements of the mold closing and locking device as an electromotive direct drive with a spindle drive and a spindle mechanism with recirculating rollers.

Abstract: The invention concerns a fuel container of plastic material such as a motor vehicle fuel tank, comprising one or more welded seams as seam locations for the body of the container and/or as connecting or sealing seams between the container wall in the region of openings and closure elements or covers welded thereto. At least some of the welded seams are at least partially penetrated by a duct which extends in the longitudinal direction in the seam and which can be filled with air and vented.
