More and more industries use the cataphoresis to coat due to its final touch quality, high productivity, efficiency and cost. Cataphoresis can be used as final touch or base before finishing the piece. One of the advantages of this process is that it is easily adjusted to original settings keeping the design tolerances on parts.
The cataphoresis is a painted method by immersion completely automated, based on the displacement of charged particles in an electric field toward the opposite sign pole. Applying an electrical potential difference molecules of paint break and are deposited on the workpiece (cathode) evenly attracted by their electrical charge. This process gives to the piece a uniform protective layer, which avoid corrosion and protects it from temperature variations and salinity.
Using cataphoresis many substrates such as rolled steel, galvanized steel, iron forgings, forgings zinc, copper/brass, forged parts and extruded aluminum, stainless steel, chrome parts, etc. can be coated. Above all, it is used for automotive pieces because it allows to reach inaccessible places as hollow areas, pipes, etc.
To perform this process achieving an optimal result it is necessary to carry out the control and analysis of certain variables. MERASYS allows control them easily.
