Abstract
Plastic container manufacturing plant comprising devices for injection-compression of plastic in molds and effected by means of at least one rotary carousel actuated by electro-pneumatic actuators, of the single-stage type integrating at least one first rotary carousel (2) for molding of the preforms and a second rotary carousel (7) for stretch blow molding of the preforms. Moreover, the plant comprises a transport system (5) between said first (2) and second rotary carousel (7) comprising further handling wheels, of which at least one (8) comprises means for thermal conditioning of the preforms.
Claims10
An integrated production plant of thermoplastic containers, in particular made of PET, comprising
- a plurality of injection-compression devices of molten thermoplastics to produce preforms for blow-moulding said containers, forming and arranged at the outer periphery of a first rotational injection-compression carousel that comprises a lower wheel and an upper wheel, said lower wheel and upper wheel having a same and unique rotation axis, the upper wheel being arranged horizontally and above the lower wheel,
- a plurality of blow-moulding devices of the preforms, forming a second rotational carousel,
- transferring means for transferring preforms from said first carousel to said second carousel,
- thermal conditioning means for conditioning preforms, arranged between the plurality of injection-compression devices and the plurality of blow-moulding devices, wherein said plant comprises actuating devices of the electric or electro-pneumatic type for actuating all the movable component parts thereof, without employing hydraulic actuation devices.
