FIELD: packaging industry.
SUBSTANCE: inner surface of the mould defines a cavity for receiving the preform. The pressure source is a servo system which has an inlet opening. Under the action of the servo system the liquid is drawn through the inlet opening and is forced into the preform. The blow nozzle is designed for receiving the liquid from the pressure source and direction of the liquid under high pressure into the perform, whereby the preform is forcibly expanded in the mould cavity to the inner surface of the mould, and the resultant container is formed. The liquid remains inside the container as a final product.
EFFECT: increased productivity of moulding and simultaneous filling of the plastic container.
