A method for the production of hollow plastic articles by means of blow molding and temporally overlapping injection molding

摘要

A method for the production of hollow plastic articles (10), comprising a plastic hollow bodies (12) with at least one integrally provided on the plastic component (14), in a form, wherein said method comprises the steps of:– Extrusion of a hollow body blank made of plastic,– Blow molding of the hollow body blank to the hollow bodies of plastic (12) in a the hollow bodies of plastic (12) associated blow mold cavity of the mold,– Injection molding of the at least one plastic component (14) in a the plastic component (14) and associated with the blow mold cavity in the form of injection mold cavity,wherein the step of the blow molding and the step of the injection molding, overlap in time, characterized in that the step ends of the injection molding process, before the hollow body blank to a blow mold cavity wall has been applied in such a way that, in spite of excess pressure in the inner region of the hollow body blank with respect to an ambient pressure, no further blowing air induced change in the shape of the hollow plastic article (12) there is no longer in the region of the blasformkavititätwand.
