Blow molding 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. One-step and two-step blow molding machine molding processes are 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 concentrated production of preforms and dispersed blown bottles; while the one-step method is more suitable for online production of beverage companies.
