二. Bottle Manufacture ⚫ Blow-and-blow process-for narrow-necked bottles ⚫ The two processes differ according to the parison producing. ⚫ Blow-and-blow process: (Figure 6.2): 1. Gob dropped into the blank mold through a funnel-shaped guide (985°C) 2. parison bottomer replaced guide ;air blown into settle mold to force the finish section. At this point the bottle finish is complete. 3. Solid bottom plate replaced parison bottomer ; air is forced to expand the glass upward and form the parison. 4. Parison removed from the blank mold, rotated to a right-side-up orientation for placement into the blow mold. 5. Air forces the glass to conform to the shape of the blow mold. The bottle is cooled to stand without becoming distorted and is then placed on conveyors to the annealing oven.二.
