PROCESS FOR THE PRODUCTION OF HOLLOW BODIES OF THERMOPLASTICMATERIAL

摘要

The invention relates to a method for producing hollow bodies (12) from t hermoplastic plastic, in particular to a method for producing plastic fuel t anks. According to said method, web- or strip-type preforms (8) consisting o f plasticised material are shaped in a multi-part (2a, 2b, 3) mould that for ms a mould cavity, by the expansion of the preform and the application of th e latter to the inner contours of the mould cavity. Two complementary interm ediate products in the form of shells (10a, 10b) are formed in a first step. Inserts (7) are then fixed to the inner faces of the shells that lie opposi te one another when installed. At least some of the inserts of complementary shells are complementary with respect to one another, in such a way that th ey can be interconnected to form a composite component or a functional unit. The shells are joined in such a way that the complementary inserts engage w ith one another and/or are operatively interconnected.
