The booth includes the entire painting system: pressurized containers, 2 guns to perform, both, internal and external painting of the tube and a collaborative robot to manipulate the guns, and consequently, paint the tube ends. Finally, a tube conveyor is in front of the painting booth, which allows the tube to have both movements: the translation movement to introduce the end of the tube into the painting booth as well as the rotation necessary during tube painting, this way paint spills is avoided. Manufacturer of special machines and equipment for all types of industry, with its own engineering or provided by the client.
