This furnace consists of pre-heating zone, pre-forming zone, forming zone, annealing zone and cooling zone. The heating power for each zone is different according to different process requirements. The wagons with glass and mould pass through the above zones in turn. After glass has been formed in forming zone, it is annealed and cooled, by now a work circulation is finished.
The whole process is controlled and monitored by computer.
Different type of glass can be loaded in different wagon. Computer control system identifies wagons automatically and bends glass according to pre-setup.
