Blowing machine

Blowing machine

The product of continuous development in the production of Zwiesel crystal glass is a blow moulding machine that enables the highest quality and can produce up to 60 glasses per minute using the blow-and-blow process.  As a result of its modular design, the construction is extremely flexible and in the case of necessary repairs, individual segments can be exchanged easily and quickly, thus downtime is greatly reduced.

The benefits of Blowing machine

  • Modular design for quick replacement / troubleshooting
  • 6 - 32 blowing stations
  • Servo-motor drive
  • Media connections with quick-change couplings for quick replacement of a station
  • Up to 60 glasses per minute thanks to "independent double-press unit"
  • A variety of blow moulding techniques

Double swivel transfer

The patent-pending "independent double-press unit (IDPU)" consists essentially of independently operating torque motor drives that provide the highest dynamics in the pivoting movement of the tools.  The pressing process is carried out using linear servo drives in order to be able to achieve the highest dynamics combined  with precision in the pressing process.

The design principle allows direct insertion of the drop into the press tool, maximum utilisation of the processing times for the pressing process by minimizing the transport times, compact design and minimal maintenance.  When placing the pre-pressed pastille, the pre-press unit follows the worktable of the blow moulding machine in absolute synchrony, and thus the pastille can be placed concentrically on the working table of the blow moulding machine.

 

The benefits of the double swivel transfer

  • No slide / tweezers are necessary for feeding the glass into the tool (carried out by the direct feed)
  • No cutting rate limitation by pre-press station - up to 70 pieces / minute can be effected without any problem
  • Maximising the process times, especially pressing time
  • When placing the pre-pressed pastille, the pre-pressing unit follows the worktable of the blow moulding machine in absolute synchrony.  Thus, the pastille can be placed concentrically on the worktable of the blow moulding machine
  • Stacking position of the pastille is freely adjustable for each station of the blow moulding machine
  • The pre-press station is usually adaptable to any blow moulding machine
  • Ground stations in the blow moulding machine are possible at any time
