The most obvious way to do the bottle is to blow the bottle into plastic by blowing machine. At present, most of the bottle blowing machines are still two-step blowing machines, that is, the plastic raw materials must be made into bottle embryos, and then blow. Nowadays, environmental protection plastics made of PET are commonly used.
Blow molding machine: after the liquid plastic is sprayed out, the plastic body is blown to a certain shape of mold cavity by using the wind force blown by the machine, so as to make products. This kind of machine is called blow molding machine. It is also a kind of bottle blowing machine. In a broad sense, blow molding machine is also a kind of bottle blowing machine! Bottle blowing machine includes blow molding machine, hollow molding machine, injection and blowing machine and two-step bottle blowing machine which are widely used now. In brief, it is a machine, and it is more careful to say that it is a machine for producing hollow containers. Generally, there are two kinds of machines: pneumatic bottle blowing machine and hydraulic bottle blowing machine. Pneumatic bottle blowing machine generally produces less than 10L, The hydraulic pressure is usually more than 10L, because of its high energy consumption.
