2. Bottles

Nowadays, bottle blow-molding machines are widely applied to fabrications of various plastic bottles (such as PET bottles). A traditional bottle blow-molding machine comprises various different mechanical parts, such as a structure for opening and closing molds, a structure for feeding material and blowing bottles, a structure for ejecting bottles, a structure for conveying and etc., wherein the structure for opening and closing molds can be designed and driven by selectively using various different power sources (such as motor, pneumatic cylinder, hydraulic cylinder or cam).”

1. Blow Molding

"Blow molding (also known as blow moulding or blow forming) is a manufacturing process by which hollow plastic parts are formed. In general, there are three main types of blow molding: extrusion blow molding, injection blow molding, and stretch blow molding. The blow molding process begins with melting down the plastic and forming it into a parison or preform. The parison is a tube-like piece of plastic with a hole in one end in which compressed air can pass through.

The parison is then clamped into a mold and air is pumped into it. The air pressure then pushes the plastic out to match the mold. Once the plastic has cooled and hardened the mold opens up and the part is ejected."
