Glass Melting
The furnace melts cullet (crushed, recycled glass), sand, soda ash, limestone, and other raw materials together. Molten glass usually ranges in temperature between 2,300 and 2,800° F. Furnace Control systems monitors and controls firing temperature. -
Cold End Coating
After annealing, a layer of polyethylene wax, is applied via a water based emulsion. This makes the glass slippery, protecting it from scratching and stopping containers from sticking together when they are moved on a conveyor. The resultant invisible combined coating gives a virtually unscratchable surface to the glass. -
Palleting & Wrapping
Glass containers are staked automatically on pallets and separated by cardboard into rows before going undergoing the shrink wrapping process. This involves a hood type film being placed over the pallet before being heated until the pallet contents are in a compact unit ensuring minimal movement of the product in transit.
At the end of the furnace, the glass stream is distributed to different forehearths for the respective production line. Molten glass is conditioned in the forehearth and its temperature gradient is equalised to ensure uniform temperature homogeneity. Plungers intercept the stream of molten glass from the forehearth and cuts gobs individually by mechanical shears. The gob distributor then routes the gobs into blank moulds at the I.S Machine.
