The molding process is mainly used, and the small-mouth bottle is formed by the blow-blow process, and the wide-mouth bottle is formed by the pressure-blow process. And Tubes are used less to make glass bottles or containers frequently.

• Blow & Blow Process – used for narrow containers where the parison is formed by compressed air.

• Pressure & Blow Process– used for large diameter finish containers in which the parison is shaped by pressing the glass against the blank mold with the metal plunger.

The production of modern glass bottles and jars widely adopts high-speed molding of automatic bottle-making machines. This kind of bottle making machine has certain requirements on the weight, shape and uniformity of the gob, so the temperature in the feeding tank should be strictly controlled. There are many types of automatic bottle making machines, among which the determinant bottle making machine is more commonly used. This kind of bottle making machine gob obeys the bottle making machine, not the bottle making machine obeys the gob, so there is no rotating part, the operation is safe, and any branch can be stopped for maintenance alone without affecting the operation of other branches. The determinant bottle making machine has a wide range of bottles and cans, and has great flexibility. It has been developed into 12 groups, double-drop or three-drop molding and microcomputer control.
