Introduction to blow molding process. Firstly, prepare the raw materials by placing plastic pellets (such as PE and PP) into the hopper of the blow molding machine. These particles are transported into the heating zone through screws in the hopper and melted at high temperatures (usually around 160-230 ℃). The melted plastic is extruded through a circular die to form a thin-walled tubular billet. Then, by blowing compressed air into the billet, the billet expands and conforms to the shape of the mold, and after cooling, a plastic film is formed. This film can be further processed into bags. For example, in the production of ordinary PE plastic bags, the blown film can be cut into the appropriate size by a hot cutting knife, and then heat sealed to make the bag.
