What is a blow molding machine?1

The blow molding machine is to use the wind blowing from the machine to blow the plastic body to a certain shape of the mold cavity after spraying out the liquid plastic, so as to make a product. This kind of machine is called a blow molding machine. The plastic is melted and quantitatively extruded in the screw extruder, and then formed by the oral film, and then cooled by the air ring, and then pulled by the tractor at a certain speed, and the winder 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), and compressed air is introduced into the parison immediately after closing the mold to blow the plastic parison. It expands and sticks closely to the inner wall of the mold, and after cooling and demoulding, various hollow products are obtained. The manufacturing process of blown film is very similar in principle to blow molding of hollow products, but it does not use a mold. From the perspective of plastic processing technology classification, the molding process of blown film is usually included in extrusion. The blow molding process began to be used to produce low density polyethylene vials during World War II. In the late 1950s, with the birth of high-density polyethylene and the development of blow molding machines, blow molding technology was widely used. The volume of hollow containers can reach thousands of liters, and some production has adopted computer control. Plastics suitable for blow molding include polyethylene, polyvinyl chloride, polypropylene, polyester, etc., and the obtained hollow containers are widely used as industrial packaging containers. According to the method of making the parison, blow molding can be divided into extrusion blow molding and injection blow molding. The newly developed ones include multi-layer blow molding and stretch blow molding.

In the office, various are considered essential since they are used to achieve particular tasks in the office. Among these , bottle blowing machine, bottle making machine, and pet bottle making machine manufacturers are widely used.
