OGS-2 semi automatic pet blowing machine is the top sales models.It suitable for producing PET bottles in all shapes. It is widely used to produce the carbonated bottle, mineral water bottle, cosmetic bottle, pesticide bottle,oil bottle, beverage bottle,alcohol bottle, medicine bottlehand sanitize bottle etc.For normal bottle it can blow up to 3L. Adopt special electronic controlling circuit for heating; high efficiency in simultaneous controlling one lamp or more; lower power consumption.  Adopt the theory of heat transfer and feedback while designing the shape and thickness of preform. The preform will be heated evenly, not be influenced by outside environment. Cooling system with cold air cycle ensures same heat exposure of internal and external surface of the bottles. The air exhaust system designed by CAD can guarantee the deviation of heating furance temperature +/-1 degree. Air circuit system consists of movement and blowing so as to meet the needs of different air pressure.
