Filling a mould by continuous casting without moulding the natural upper surface aims at three different target productions:
First, for billet-casting � providing improved glass quality and better working conditions for manual production, since high-quality glass in precisely defined quantities is provided by the feeder.
Second, for casting solid glass raw material which is re-heated and moulded in a second production step (glass rods and gobs, i.e. for lenses for automotive lighting) or high-intensity colour glass rods for feeder-channel colouring.
Third, for heavy, plain-shaped glass items which integrate the plain (natural) surface into their design. The casting system may be combined with gob feeding and continuous casting (in combination with the horizontal movement of the telescope unit and the base lifting system/roundtable).

With regard to the capacity of the production system, two alternative casting systems are available:
                    � the linearystem                 � the roundtable system

The telescope unit or the roundtable moves the empty water-cooled mould under the orifice of the feeder. The glass stream is received by the raised base of the mould and is filling the mould, while the base of the mould is lowered slowly. After the glass stream is sheared, the mould containing a precisely defined quantity of glass moves to the take-out position. The finished glass item may be taken out or the billet may be processed by the glass-blower. Unused billets are automatically disposed of.
