Blowing process extrusion
Did you know?
In extrusion blow molding, plastic is melted and extruded into a hollow tube (a parison). Then the parison is captured by closing it into a cooled metal mold. Air is then blown into the parison, inflating it into the shape of the hollow bottle, container, or part. After the plastic has cooled sufficiently, the mold is opened and the part is ejected.
