BB (Blow-and-Blow)
Traditional process — gob is settled and counter-blown into a parison in the blank mould, then transferred and final-blown in the blow mould.
Settle pin
On blow-and-blow, settles the gob into the bottom of the blank mould via low-pressure air; controls bottom-of-bottle thickness.
