Back to Plastic Blow Molding

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 extrusion blow molding, injection blow molding, and advanced blow molding processes.

Part of the Fundamental Manufacturing Processes Video Series, this program provides a detailed discussion of production processes, presenting a clear understanding of the similarities and differences between each of them. Information on parison and preform production is provided.

The extrusion blow molding segment looks at both intermittent extrusion blow molding and continuous extrusion blow molding processes. The extrusion head and die assembly and machine types, such as the reciprocal screw style blow molding machine, and the accumulator style blow molding machine are featured.

The injection blow molding segment examines the various stations in the process, including the injector station, the blow station, and the strip (or eject) station.

The advanced blow molding processes segment details both single and two-stage bi-axial stretch blow molding and the co-extrusion blow molding processes.
