This process produces hollow plastic parts. One of three processes are used: extrusion blow molding, injection blow molding, and stretch blow molding.

This process injects the desired material by high pressure, in this case plastic, into a mold to produce the finished product.

This process provides high volume production of continuous plastic products such as pipes, tubes, railing, plastic films and sheets.

(Reaction Injection Molding) is similar to Injection Molding except the material is thermosetting polymers and it must be cured inside the mold.

This process uses a heated hollow mold filled with a charge or shot weight of material. It is slowly rotated causing the softened material to cover walls of the mold.

This process uses a plastic sheet, which is heated to a forming temperature and formed to a specific shape and trimmed to the desired product.

This process, much like Thermoforming, uses multiple sheets of plastic, which are heated to a forming temperature, formed and trimmed to the desired product.
