WALTEC supplies a whole range of feeder components: forehearths, colouring forehearths, fireproof and platinum feeder heads, rotating tube mechanisms, servo-feeders, servo-shears, gob guiding systems and line synchronisation controls.
Encapsulated linear motor driven mechanisms with high-pressure oil lubrication guarantee long life and reliability – at cutting speeds of up to 220 per minute.
The high quality of the Siemens standard control components and the software, programmed by WALTEC-specialists, guarantee excellent repetition accuracies. This results in the highest gob weight consistency for the glass production.
Flexible, malleable and digitally controlled plunger stroke profiles replace the mechanical cam. The VG 4 supplies up to 12 variable gob weights with a weight range of up to +/- 35 % (soda lime glass) of the average weight.
The VGx, developed by WALTEC, has been applied with great success in the packaging glass industry for small and medium batch sizes. For the multiple gob operation, up to four independent mechanisms operate on one feeder head.
