The invention relates to PETG vacuum extruding molding processing equipment, containing an extruding mechanism, a molding mechanism, a drawing mechanism and a cutting table; the extruding mechanism, the molding mechanism, the drawing mechanism and the cutting table are connected in sequence to form a processing production line; a material supplier is arranged at the front end of the extruding mechanism. According to the PETG vacuum extruding molding processing equipment and a production process thereof, molding of PETG tube, bar, strip and irregular-shaped sections is finished by extruding through an extruding molding die, a small-sized cooling molding die, and the processing manner of a vacuum method; the limitation that the past PETG material can only be produced into sheets, panels and films through a plastic uptaking production mode, an injection molding production mode, a bottle blowing production mode or an extruding production mode is broken through, expenditure of the die is greatly reduced, the tubes, bars, strips and irregular-shaped sections can be produced in quantity efficiently, and a PETG vacuum method-extruded molding product can be produced by only matching a specific small-sized and simply-designed cooling molding die and lubricant.
