Hollow blow molding brief introduction

In the hollow blow molding process, the semi-molten tube blanks (parisons) obtained by extrusion or injection molding are placed in molds of various shapes, and the tube blanks are blown with compressed air to make them adhere to the molds. On the cavity wall, the mold is then cooled and demoulded to obtain a hollow product. The molding process includes the production of plastic parisons and the blowing of parisons. This molding method can produce various packaging containers such as bottles, pots, and barrels with different calibers and capacities, daily items, and children's toys.

Polyethylene, polyvinyl chloride, polypropylene, polystyrene, linear polyester, polycarbonate, polyamide, cellulose acetate, and polyacetal resins are used in the hollow blow molding plastics. Among them, the consumption of high-density polyethylene accounted for the first place. It is widely used in the packaging of food, chemical and processing liquids. High molecular weight polyethylene is suitable for the manufacture of large fuel cans and barrels. Because of its good transparency and airtightness, polyvinyl chloride is commonly used in the packaging of cosmetics and detergents. With the development of non-toxic polyvinyl chloride resins and additives, and the development of stretch blow molding technology, the use of polyvinyl chloride containers in food packaging has rapidly increased and has begun to be used for the packaging of beer and other beverages containing carbon dioxide gas. . Linear polyester material is a new material that has entered the field of hollow blow molding in recent years. Because its products have a glossy appearance, excellent transparency, high mechanical strength and good preservation of the contents of the container, waste incineration treatment does not pollute the environment and other advantages, so the development of the packaging bottle is very fast, especially It is most widely used in pressure-resistant plastic food containers. Polypropylene has been used year after year due to its resin modification and processing technology.

Hollow blow molding can basically be divided into two major categories: extrusion - blow molding and injection - blow molding. The main difference between the two is the preparation of the parison, and the subsequent blow-molding process is basically the same. On the basis of these two molding methods are developed: extrusion - stretching - blow molding (referred to as extrusion - pull - blowing), injection - stretching - blow molding (referred to - pull - blowing) and multilayer mapping Plastic and so on.
