Plastic blow molding processes are the most popular methods used to produce hollow products out of thermoplastic materials. Blow molding is performed using a wide variety of production methods, including: intermittent and continuous extrusion blow molding, injection blow molding, single and two stage bi-axial stretch blow molding, and co-extrusion blow molding. Through the use of shop floor footage and animations this program provides a detailed discussion of each of these processes, presenting a clear understanding of the similarities and differences between each of them. In addition, information on parison and preform production, the reciprocal screw style blow molding machine, the accumulator style blow molding machine, and the head and die assembly is provided.
