SCOPE OF SUPPLY OF SMF'S BOTTLE PRODUCTION SYSTEMS
The complete set delivered to customers, apart from the PP or PET blowing machine, usually consists of the following equipment:
- Preform feeding system with accumulation container (hopper), preform conveyor, orientator and gravity rails. It also includes electric and steering components.
- Preform tilter DUMPER DR-310 (optional) - machine designed to automate the process of PET containers production. Thanks to that solution, preforms are supplied to the hopper automatically. The operator needs only to change pallets with the octabins filled with preforms. It makes the process faster and easier.
- Bottle exit conveyor - depending on the machine, it can be directly connected to the conveyor, which transports bottles to the filler (OPTIMA, STRATOS, VARIO) or may deliver bottles to the unscrambling system (COMBI, HS).
- Electric cabinet and machine steering system - they are based on components of well-known brands and meets all the European standards and requirements.
- Compressors station is based on screw compressors made by German company KAESER which cooperates with SMF for over 12 years. The complete set consists of screw compressor, booster, air dryers with filters, air tanks, connectors and steering box. The parameters of the compressors station are adjusted individually to each blowing machine.
- Water cooling system - SMF machines are equipped with water cooling system which includes efficient water chiller.
