Blow Molding

The extrusion blow molding process begins with the conventional extrusion of a parison or tube. The parison is commonly extruded downward between the two halves of an open blow mold. Air is blown into the inside of the parison to expand the molten plastic against the mold surface. The plastic is cooled as it conforms to the new shape. After the bottle cools, the mold opens to eject the bottle and the excess plastic is trimmed from the neck and bottom pinch-off areas. Most finishing steps can be completed in-mold but some involve secondary operations.
