What is the basic working principle of a blow molding machine?
A blow molding machine is a plastic processing machine. After the liquid plastic is sprayed out, the wind blown by the machine is used to blow the plastic body into a mold cavity of a certain shape to make a product. This machine is called a blow molding machine. The plastic is melted and quantitatively extruded in the screw extruder, and then formed through a mouth film. It is then blown and cooled by an air ring. Then a tractor pulls it at a certain speed, and the winding machine winds it into a roll.

Blow molding, also known as hollow blow molding, is a rapidly developing plastic processing method. The tubular plastic parison obtained by extrusion or injection molding of thermoplastic resin is placed in a split mold while it is hot (or heated to a softened state). After the mold is closed, compressed air is immediately introduced into the parison to blow the plastic parison. It expands and adheres closely to the inner wall of the mold. After cooling and demoulding, various hollow products are obtained.
