摘要： The invention concerns a process for the production of hollow bodies made from thermoplastic material by extrusion blowing. The process calls for discontinously produced preforms to be stretched in a blowing mould. During at least part of the extrusion-head loading phase typical of a process of this kind, the distance covered by an ejection piston (19) associated with the storage space (18) and the speed with which the ejection piston (19) is forced through the plasticized material in the storage space (18) are measured and each compared with a target value by a central control unit. Depending on the result of this comparison, at least one process parameter, e.g. extruder (10) throughput or ejection-piston (19) delivery-stroke length, can be adjusted in the same cycle so that substantially the required preform volume is ejected.

摘要： The invention concerns an injection-moulding machine for thermoplastics, the machine having at least one plastifier unit (10), at least one injection-moulding cylinder (11) with its associated discharge piston (18), and at least one mould (12). The injection-moulding cylinder (11) is fitted with a sleeve (16) which is disposed so that it can move back and forth between a position in which the connection to the mould is cut off and a position in which the connection to the mould is established. In the position in which no connection to the mould exists, there is a passage between the sleeve (16) and housing (14) which is connected to the feed channel (46) from the plastifier unit (10) and also to the storage space (27) inside the sleeve (16). The outside diameter of the discharge piston (18) is slightly smaller than the internal diameter of the sleeve (16) so that, between the two, there remains an annular gap through which the plastic can enter from one end (28) of the sleeve (16) into the storage space (27).

摘要： In a process and apparatus for the production of hollow bodies from thermoplastic material, having a wall of a laminate formed by at least first and second layers, by means of extrusion blow molding, a preform having a wall structure with a suitable number of layers is first produced in a batch-wise procedure using an extrusion head. The material required to produce the preform is guided in the extrusion head in such a way that disturbed portions of the laminate pass into the waste flash portions at the ends of the hollow body produced from the preform, so that the wall of the finished hollow body is devoid of disturbed laminate portions of that kind.

摘要： In a process and apparatus for producing elongate curved hollow bodies at least partially comprising thermoplastic material a preform is extruded from an extrusion system head and engaged by a gripping means. The preform is moved by the gripping means into the region of a guide stencil disposed above the mold cavity of a mold portion of a divided blow molding mold and introduced into the mold cavity by a simultaneous downward movement of the gripping means and a movement following the configuration of the guide stencil. The guide stencil has two mutually opposite walls, the spacing of which increases in an upward direction and the spacing of which at the bottom of the guide stencil approximately corresponds to the maximum width of the mold cavity. The preform is thus guided towards the mold cavity by the walls, acquiring its definitive orientation with respect thereto by virtue of such guidance, passing through a lower opening in the guide stencil into the mold cavity. The mold is closed and the preform expanded therein by an increased internal pressure in the preform.

摘要： In a process for the production of a hollow body of thermoplastic material which is to include an additional portion, by expansion of a preform in a blow molding mold, the additional portion is connected to the hollow body upon expansion of the preform to form the hollow body. To form the connection between the hollow body and the additional portion, the latter is heated by a heating element which is brought into contact with at least the surface of the additional portion that is to involve the welded connection to the hollow body, prior to expansion of the preform. The heating element is brought into contact with the additional portion when already disposed in the blow molding mold in order in that way to heat at least the appropriate surface of the additional portion to a temperature which premotes the production of an adhesive join to the hollow body. The region of the additional portion that is to be heated is at least substantially covered relative to the outside atmosphere by the heating element.

摘要： A process and apparatus for the production of hollow bodies from thermoplastic material by means of blow molding uses a blow molding mold which includes at least first and second mold portions to enclose a generally tubular extruded preform which is expanded within the mold under the effect of an increased internal pressure within the preform. To provide for asymmetric closing and/or opening movements of the mold portions relative to the preform, the blow molding mold is displaced as an entirety parallel to the direction of the opening and/or closing movements of the mold portions, more especially during the mold closing and/or opening procedure, so that an additional motion is superimposed on the movements of the mold portions.

摘要： A barrel of thermoplastic material has a peripherally extending carrier and transportation ring in the region of its upper end portion and at least one plughole connection in the edge region of the latter. The bung hole connection is disposed within a housing which is let into the upper end portion. The housing is open at its side towards the edge of the barrel while at its other side it has a boundary end wall, from each of the two ends of which a respective wall extends towards the edge of the barrel, the walls laterally defining the housing. The walls defining the housing are delimited at the top side by a transition from the respective wall into the upper end portion of the barrel and at the lower end by a transition from the respective wall into the bottom of the housing. The spacing between the upper transitions of the two ends of the housing is greater than the spacing between the two lower transitions and the upper transitions diverge towards the edge of the barrel. The transitions between the side walls and the upper end portion of the barrel body on the one hand and the transitions between the side walls and the bottom of the housing on the other hand do not extend parallel. The transitions between the side walls and the upper end portion include an angle which is at least 120.degree..

摘要： An injection molding apparatus for processing thermoplastic materials has at least one plasticizer unit, at least one injection molding cylinder with associated emptying piston, and at least one injection molding mold. The injection molding cylinder is provided with a sleeve which is arranged reciprocally between a position in which communication with the injection molding mold is interrupted and a position in which communication with the injection molding mold exists. In the position in which the communication with the injection molding mold is interrupted, a passage is provided between the sleeve and the housing which is connected between the feed conduit from the plasticizer unit and a storage space defined on the inside by the sleeve. The outside diameter of the ejection piston is slightly smaller than the inside diameter of the sleeve so that remaining between the two is an annular gap through which the plastic material passes into the storage space from one end of the sleeve.
