What is the difference between blowing and blow molding?


In a broad sense, the blow molding machine is also a kind of blow molding machine! Automatic blow molding machines include blow molding machines, blow molding machines, injection blowers and more two-step blow molding machines nowadays!


Simply speaking, it is a machine. 
It is said that it is a machine for producing hollow containers. 
There are generally two kinds of pneumatic blowing machines and hydraulic blowing machines. The pneumatics are generally produced within 10L, while the hydraulic pressure is generally considered to be more than 10L, because his energy High consumption.

Blowing machine: It is the machine that blows the bottle. The most obvious explanation is the machine that can blow plastic pellets or finished preforms into bottles by certain means.

At present, most of the blow molding machines are still two-step blow molding machines, that is, the plastic raw materials must first be made into preforms and then blown. Currently commonly used in PET is environmentally friendly plastic.

Blow molding machine: After the liquid plastic is sprayed out, the wind is blown out by the machine, and the plastic body is blown to a cavity of a certain shape to make a product. This machine is called a blow molding machine. It is also a kind of blow molding machine.

The difference between blowing and blow molding

Blow molding process: Blow molding is made of pipe (when the wall is very thin, it is a film), which is characterized by continuous production and is an extrusion process.

Blowing process: It is specially used for bottle making. The tubular blank is extruded or injected into the mold, inflated, and the wall of the pipe is molded into a bottle. It is a combination of extrusion and injection molding.
