Blow molding ( BrE moulding ) is a manufacturing process by which hollow plastic parts are formed. In general, there are three main types of blow molding: extrusion blow molding, injection blow molding, and injection stretch blow molding. The blow molding process begins with melting down the plastic and forming it into a parison or in the case of ...

A method of fabrication in which a warm plastic parison (hollow tube) is placed between the two halves of a mold (cavity) and, by using air pressure, the parison is forced to assume the shape of the cavity. The air pressure is introduced through the inside of the parison. The air pressure forces the plastic against the surface of the mold that defi...

A process for the production of hollow thermoplastic shapes. This method of fabricating involves a plastic parison (hollow tube) placed between two halves of a mold (cavity) and by using air pressure the parison is forced to take the shape of the cavity. The air pressure is introduced through the inside of the parison. The air pressure forces the p...
