CED Coating utilizes the concept of using electric current to deposit paint particles on the component. A bath of suitable size with anode immersed is required with paint solution wherein the part is the cathode which is immersed for painting. The electric current causes the paint particles to stick on the components. The dip time is calculated based on the DFT of the paint required. The entire line would consist of arrangements of tanks as per the pretreatment and coating requirements. The bath temperature needs to be regulated and kept below 25 Deg Centigrade to avoid paint coagulation. A chiller unit and heating mechanism is utilized to maintain the temperature. The Ultra filtration system for reusing the paint after separation is very specialized. The material movement could be done on conveyors or on transporters as per the product quantity and requirement.
There are an entire lot of advantages which make CED coating process as an ideal primer process. The list is as follows:
- Excellent coverage in sharp corners and interiors.
- No run over and paint sagging problem
- Nearly 100% paint utilization.
- Uniform coating thickness
- Film thickness can be controlled as per requirement.
- Better corrosion resistance and no paint chip off problems
- No solvent boils
- Low cost of part painting in comparison to painting process when painted in large volumes.
- No health hazards, no operator safety problems and excellent in meeting anti-pollution standards. Low in disposable treatment.
