ELECTROCOATING/E-COAT SYSTEMS

     Total Finishing Systems is proud to be partnered with Erzinger, an industry leader in the design and manufacturing of Electrocoating (E-Coat) Systems. To Erzinger painting is not just aesthetics, it is technology, durability, and longevity. With more than 45 years of experience in the E-Coat market, Erzinger is one of the largest manufacturers of E-Coat systems in the world. 

What is electrocoating (e-coat)?

E-coat is a painting process that works under the principle of attraction of opposite poles. 


It occurs when a conductive object, immersed in a paint bath, is subjected to an electric current, this object being interconnected to one of the poles and the part particles or electrodes to the other pole. The result of this process is always a continuous and uniform coating that confers excellent resistance to corrosion.

CONTINUOUS E-COATING LINES

 Erzinger's continuous E-Coating lines feature simplified automation and high productivity as a differential. They are built in order to adapt to the different spaces available, through the development of customized layouts to the client's needs. Erzinger has the entire portfolio of adjacent products necessary for the proper functioning of this type of solution, such as sprinkler pre-treatment tunnels, continuous greenhouses of the most diverse construction models, medium and high load capacity overhead conveyors, among other equipment if needed.

1 - Pretreatment

 Its purpose is to act on metallic surfaces by chemical deposition. The main objective is to guarantee the final resistance of the product against corrosion, excessive wear of parts or equipment, when subjected to mechanical stress, and to provide an anchorage for the coating (painting).

2 - Anodes

1 - Pretreatment

1 - Pretreatment

 The part to be painted constitutes the cathode of a direct current circuit and the negative pole of the rectifier is connected to it, the positive pole (anode) is a stainless-steel plate or tube that is housed inside the dialysis cell. Dialysis cells are used to remove the acid that is continually released during the painting process. By controlling and maintaining the acid level of the ink bath, the cell ensures constant pH and conductivity.

4 - Anolyte Tank

Its function is to remove excess surface paint from the E-Coat, making the parts drag as little paint particles as possible to the next stage.

5 - Cooling and Filtration

4 - Anolyte Tank

Constructed with Polypropylene, this tank uses a pump to move anolyte to the dialysis cells that are positioned on the side of the KTL-E01 tank (KTL-X01 to KTL-X32), in order to remove the acidity of the paint. This tank has 20 flowmeters for flow indication, one for each anode. At the output of the pump, there is a conductivity meter to indicate the conductivity of the tank, which is monitored/controlled by the PLC.

5 - Cooling and Filtration

Its function is to maintain the paint temperature according to the project scope. E-coat paint must be temperature controlled in the main and reserve tanks. For this, a thermo chiller is responsible for generating water at a controlled temperature, passing through the plate exchanger, exchanging the temperature with the ink. A filtering system using bag filters and magnetic bars filters the paint before entering the plate changer.

5 - Cooling and Filtration

5 - Cooling and Filtration

Responsible for cooling or heating the paint through a plate exchanger in order to keep its temperature stable (temperature defined by the paint supplier). This equipment is an integrated part of the painting line.

7 - E-Coat Paint Tank

8 - Ultrafiltered Tanks

8 - Ultrafiltered Tanks

This is the main tank that performs the painting of the parts through the electrodeposition process. This process consists of immersing the object to be painted in a bath of paint diluted in D.I. water, where a continuous electric current is passed and, through a potential difference, an organic coating is deposited. This coating forms a uniform and cohesive film on the surface of the part.

The ultrafiltered tanks remove excess E-Coat paint deposited on parts after the painting process. The bath used is called permeate (ultra filtrate). Rinsing the parts with the permeate allows the recovery of paint that did not adhere to the part, but which was mechanically dragged by it.
