Abstract
Procedure for the manufacture of hollow articles of thermoplastic material that consists of injection molding a preformed part in a thermoplastic temperature range of the material, cooling the preformed part to a temperature located within the thermoelastic temperature range without prior cooling to a temperature lower and blow-mold the preformed part giving it the desired final shape, characterized in that the optimal temperature profile of the preformed part is obtained by partial expansion of the preformed part so that it comes into contact with the internal walls of an intermediate mold and by that a different direct temperature exchange is made locally between the mold walls and the dilated preform.
