Blowing machines are mainly divided into three categories: extrusion blow molding machines, injection blow molding machines and special structure blow molding machines.
The processing technology is mainly divided into one-step method and two-step method. 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 type of blow molding machine, namely a hydraulic bottle blowing machine.
One-step and two-step blow molding machine molding process, mainly used for PET and BOPP hollow container molding. Both have their own characteristics and are widely used. In comparison, the two-step method is more suitable for centralized production of preforms and dispersion-blown bottles; and one-step equipment is more suitable for online production of beverage companies.
