Single-stage process: The bottles are produced on machines that implement both steps 1 and 2 by using PET raw material to mould preforms and then directly stretch-blow-moulding these preforms into the finished bottles or jars.

• The plastic melt is injected into the parison under low injection pressure, and the neck of the bottle is precisely shaped. After proper control, the mold is opened and the mandrel and parison are transferred to station 2 for stretching and blowing.
• Blow molding is completed in this cavity by cooling and forming station. (The mold cavity determines the shape and appearance of the bottle). The parison is inflated by the air coming out of the mandrel and close to the mold. Then, the mold is opened and the mandrel and the parison are transferred together
• Demoulding is completed at this station, and then packaging or filling is carried out through the assembly line. The three actions of injection, blow molding and demoulding are carried out at the same time, which is highly efficient and energy-saving.

​The one step method was preferred by jar supplier and empty bottle supplier because the entire molding process is done with only 1 machine. The two step method requires 2 machines, one to make the preform and another one to process it, requiring more energy to operate. In addition to being more efficient, the one step method allows more flexibility of shapes and geometries when processing because the preform is stretch blown immediately into the blow cavities which gives greater control of wall thicknesses. The visual quality of the part produced using the one step method is also much higher.
