3. Blowing Technology Controlling

Discharge warmed pre-forms to outlet guide by discharge pre-form cover, put pre-forms into blowing moulds by manipulator, seal the bottle mouth and extrude the body, also inlet two grade air pressure(pre-blowing pressure and high pressure air) and make pre-form to be bottles. According to the requirement of art, there will inlet cooling water for moulds, all above processes are controlled by main machine computer.
