Pet Stretch Blow Molding Process

Stretch Blow Molding is a process used for producing bottles commonly used for water, juice and other related items. In this process, a preform is loaded into the automatic PET stretch blow molding machine(preform is typically produced on an injection molding machine) where it is heated up and blown into a finished container. PET is the main material used for this process but other materials can be used like PP, tritan, etc in PET stretch blow molding machine.
