Blow Molding Process
Blow molding is a process that uses pressurized air to inflate heat softened plastic into a mold cavity. It is an industrial process for making hollow plastic parts with thin walls without seams, such as bottles and similar containers. Since many of these items are used for consumer beverages, production is typically organized for very high volumes of product. The technology was influenced from the glass blown container industry. Which are now industry rivals in the disposable or recyclable bottle market. The blow molding process is completed in two steps: fabrication of a starting tube of molten plastic, called a parison, and inflation of the tube to the desired final shape.
