Maintenance of blow molding machine

Bottle blowing technology was used to produce vials during the Second World War. Born in the late 1950s, with the development of high-density polyethylene and blow molding machines, blow molding technology has been widely used.

The volume of the hollow container can reach thousands of liters, and production is now controlled by a computer. It is suitable for blow molding of polyethylene, polyvinyl chloride, polypropylene, polyester and other plastics. The income of empty containers is widely used in industrial packaging containers. According to the manufacturing method of parisons, blow molding and blow molding can be divided into extrusion blow The newly developed multi-layer blow molding and stretch blow molding and then the molding and injection molding of the bottle blowing machine also began its journey.
