Abstract
This work presents the design and construction of a dip-coater revolver machine to manufacture homogeneous coatings on metallic substrates. The material used for the fabrication of the machine structure was 6061-T6 aluminum. A Nema 23 stepper motor of 4.2 A and 24 V with a speed reducer with a 10:1 ratio that can provide an angular velocity ω between 1-80 rpm was used for the motion system. DC linear actuator was used for the immersion process, which operates in the range of 12-24 V at 7 A, with a stroke length of 50 mm and a maximum linear speed of 12 mm/s. For the coating tests, SayerLack® black and white base paint was used on 6061-T6 aluminum substrates and 304 stainless steel substrates. Finally, the mathematical model and the simulation of an automatic PID control system were carried out to automate the coating manufacturing process.
