The history of blow moulding for the manufacturing of plastic containers

Blow moulding of plastics originates from glass blowing process. Enoch Ferngren and William Kopitke produced the first machine conceived for this process, later sold in 1937 to the Hartford Empire Company, a step that determined the birth of commercial blowing. As they had to replace such a brittle material like glass, plastic was introduced in the process: the first manufacturing of plastic bottles dates back to 1939, in the United States, followed by Germany. Today, Germany is one of the leading manufacturers of blow moulding machines, for the production of plastic items, such as plastic containers.

Blow moulding process in the manufacturing of plastic containers

The blow moulding process of plastic materials consists in:

  • Introduction of granule raw material in a heated cylinder.
  • Extrusion and injection of the melt material, so to form a preformed plastic hollow tube.
  • Coupling of the preform in a suitable mould according to the final shape of the product.
  • Air blowing into the plastic, until it adheres to the walls of the mould.
  • The process of blowing finishes with the cooling of the material and the uncoupling of the mould so the final product is obtained.

In the industrial manufacturing of plastic containers, Fisem combines the experience of its technicians to a production line equipped and technologically advanced, offering unique custom-made solutions.
