The Development History Of Bottle Blowing Machine

2021-09-24

Blow molding machine refers to a machine that blows bottles. The most simple explanation is a machine that can blow plastic particles (softened into liquid) or finished preforms into bottles through certain technological means. The Bottle Blowing Machine is convenient and quick, and has a large amount of molding. After its appearance, it replaced most of the manual bottle blowing and was adopted by most beverage companies.

Enoch Ferngren and William Kopitke first verified the blow molding process. The principle of this process is derived from glass blowing. In 1938, Ferngren and Kopitke built a Blow Molding Machine and sold it to the Hartford Empire Company. This is the beginning of the commercial blow molding process. In the 1840s, the variety and quantity of plastic products were very limited. Therefore, the blow molding process did not develop rapidly until very late. With the increase in product types and the increase in productivity, more and more plastic products are made by the blow molding process soon. In the US soft drink industry, the number of plastic containers has grown from zero in 1977 to 10 billion in 1999.

The blow molding process was 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 the hollow container can reach thousands of liters, and some production has adopted computer control. Plastics suitable for blow molding include polyethylene, polyvinyl chloride, polypropylene, polyester, etc. The resulting hollow containers are widely used as industrial packaging containers.
