二. Bottle Manufacture Figure 6.3 Press and blow forms the parison by mechanical action ⚫ Gob delivery and settle-blow steps are similar to blow-and-blow forming. ⚫ Parison is pressed into shape with a metal plunger rather than blown into shape(Figure 6.3). ⚫ The final blowing step is identical to the blow-and-blow process. ⚫ Used for smaller necked containers. ⚫ Better control of glass distribution press-and-blow process-for wide-mouthed jars二.
