Shaping apparatus for the shaping of plastics material pre-forms into plastics material containers |
摘要 |
The invention relates to a shaping apparatus (1) for the shaping of plastics material pre-forms (10) into plastics material containers (10A) with a plurality of blow moulding stations (8) and with at least one control device (55; 55A; 55B; 55C) for the control of blow moulding pressures and/or volume flows at the blow moulding stations (8), in which the at least one control device (55; 55A; 55B; 55C) comprises at least one control valve (56) with a control piston part (58) which is guided in a cylinder part (57) and by means of which a cross-section (59) of a blow moulding air duct (60) is capable of being closed, wherein the control device (55; 55A; 55B; 55C) has a drive unit (61) operating in an electromagnetic manner in order to effect a change in position of the control piston part (58) inside the cylinder part (57) and thus also to control the blow moulding pressures and/or volume flows at the blow moulding stations (8). |
