[0036] Working principle: The operation of the plastic extruder can be controlled by the controller 6. By placing the plastic material on the inner side of the feeding tank 13 and starting the electric valve 12, the plastic material inside the feeding tank 13 is transported to the inside of the extruder body 2 through the feeding pipe 11.
