An extrusion blow-molding machine for producing hollow bodies, in particular bottles (20), comprising an extruder head (30), a blow molding tool (40) with a cavity (41), and a blowing mandrel (70), wherein the extrusion blow molding machine has a cooling mold (60) with a cavity (61) corresponding to the finished hollow body for cooling the blown hollow body.
A method for producing a hollow body, in particular a bottle (20), comprising the steps of:
- extruding a parison (21) from an extruder head (30),
- inserting this extruded parison (21) into a blow molding tool (40),
- inserting a blowing mandrel (70) into the extruded parison (21) in the blow molding tool (40),
- inflating the parison (21) to form a hollow body,
- demolding the hollow body,
- wherein the hollow body is placed in a cooling mold (60) after demolding.
