The manufacture of PET containers can be made with a 1-step or a 2-step process. The 1-step process, based on the concept of integrating the preform injection process with the preform stretch-blowing process, results in a container obtained directly from plastic resin in a single machine. The 2-step process features the manufacture of plastic containers in two separate stages: first preforms are injection molded on an injection machine and then are re-heated and stretch-blown on a blowing machine.
