Apparatus and method for the continuous cycle production of containers from plastic material

A method for the continuous cycle production of containers from plastic material, comprising the following steps:

• receiving in a metering unit a flow of molten plastic produced by an extruder;
• separating from the flow of molten plastic a plurality of doses simultaneously through a respective plurality of outlets of the metering unit;
• providing a plurality of female compression elements to define a corresponding plurality of seats;
• receiving the plurality of doses in the corresponding plurality of seats of the plurality of female compression elements;
• providing a plurality of male elements that is configured to act in conjunction with the plurality of female compression elements to define a corresponding plurality of forming cavities;
• compressing each dose into a respective forming cavity by means of the plurality of male elements so as to make a plurality of parisons simultaneously by compression moulding;
• receiving the plurality of moulded parisons in a blow moulding station and blow moulding the plurality of parisons to form a corresponding plurality of containers.

An apparatus for the continuous cycle production of containers from plastic material, comprising:

• a metering unit configured to receive from an extruder a flow of molten plastic and including a plurality of outlets configured to produce a corresponding plurality of doses simultaneously from the flow of molten plastic;
• a forming station including a plurality of female compression elements defining a corresponding plurality of seats;
• a plurality of male elements acting in conjunction with the plurality of female compression elements to delimit a corresponding plurality of forming cavities and being configured to compress the plurality of doses by forcing each of them to occupy the respective forming cavity so as to make a plurality of parisons simultaneously by compression moulding;
• a blow moulding station, configured to receive the parisons of the plurality of parisons and to blow mould the plurality of parisons to form a corresponding plurality of containers, in which the plurality of seats is configured to receive simultaneously, indirectly or directly, the plurality of doses of the plurality of outlets of the metering unit.
