    Evolution of blow molding

    The blow molding process began to be used to produce low density polyethylene vials during the Second World War.  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 vessels can reach thousands of liters, and some production has been computerized.  Suitable for blow molding plastics such as polyethylene, polyvinyl chloride, polypropylene, polyester, etc., the hollow containers are widely used as industrial packaging containers.  According to the billet production method, blow molding can be divided into extrusion blow molding and injection blow molding, the new development of multi-layer blow molding and stretch blow molding."  

    Blow molding application

    Extrusion blow molding is a method of making hollow thermoplastic parts.  Well-known blow molding objects are bottles, buckets, cans, boxes and all containers for packaging food, beverages, cosmetics, medicines and daily necessities.  Large blow molded containers are commonly used for packaging of chemical products, lubricants and bulk materials.  Other blow molding products include balls, bellows and toys.  For the automotive industry, fuel tanks, car shock absorbers, seat backs, center brackets, and armrest and headrest coverings are blow molded.  For machinery and furniture manufacturing, blow molded parts can be shells, door frames, frames, POTS or boxes with an open face.  Generally common are People's Daily items such as: bottles, cans, baby products, sporting goods and so on.

    • HDPE injection molding grade has good balance of rigidity and toughness, good impact resistance and excellent of low temperatures resistance and good environmental stress crack resistanse. The resin has good rigidity and abrasion resistance, and good processability.
    • Polyethylene consists of hydrocarbon chains with the most basic component being the ethylene molecule, consisting of 2 carbon and 4 hydrogen atoms. When ethylene molecules are combined together in straight or branched chains, polyethylene is formed. This process involves splitting the double bond between the 2 carbon atoms and creating a free radical to join to the next ethylene molecule. The macromolecules are not covalently joined, but are held together in a crystalline structure through intermolecular forces. The lower the number of side branches, the lower the crystallinity and hence the higher the density as can be observed in the differing properties for differing types of polyethylene.
    • Thermoplastic matrix polymer composites have gained commercial success in the semistructural and structural applications. Polyethylene (PE) is one of the most versatile and widely used thermoplastics in the world because of its excellent properties like toughness, near-zero moisture absorption, excellent chemical inertness, low coefficient of friction, ease of processing and unusual electrical properties.
