A two stage process where a preform or parison is injected molded. The bottle finish is formed at this time. The preform is then transferred to a blow mold where the bottle takes its final shape.
A molding process in which heat-softened polymer is injected from a Plastifier into a mold cavity creating a Preform, which is then transferred to a Blow Mold where air is blown into the Preform, forcing it to take the shape of the Blow Mold cavity.
A blow molding process by which the parison is formed by injection molding during a step in the cycle of a machine’s operation.
A blow molding process in which the parison to be blown is formed by injection molding.
Suited for containers that have very close tolerance threaded necks, wide mouth openings, and highly styled shapes. In the basic process, plastic melt is injected as a parison into a preform cavity forming the preform around a core rod. A completely finished injection molded neck is formed at this station. The preform is indexed to the flow station where it is blown through an opening in the core rod into the final shape.
A molding procedure whereby a heat softened plastic is forced from a cylinder into a relatively cool cavity which gives the article the desired shape.
