CED Coating Process

Electrocoating, which is also referred to as electro deposition, electrophoretic deposition, CED Coating, CED Painting or electropainting, is an organic finishing process that uniformly applies thin-film primers and one-coat finishes to metallic substrates.

CED coating is used extensively in the automotive industry. In this process, the component after phosphate pre-treatment is dipped in the bath of E-coat chemicals and given an electric charge. The coating gets deposited on the component and then it is removed from the bath, washed and then baked.

This technology gives an organic finish on metal part/component by electrically depositing paint on it. Cathodic electrocoating are high performance coatings and can withstand the harshness of exterior environment.

The preparation steps for E-coat are identical to plating steps in that the metal surface must be chemically clean. 

Typical steps in an E-coat process for metal parts: 

1. Cleaning 

2. Rinsing

3. Acid etching

4. Rinsing

5. Wetting agent dip

6. E-coat

7. E-coat rinsing and recovery

8. DI Rinsing

9. Curing with either convection or infra-red oven(or both)

IGBT Rectifier Advantages Over SCR Rectifier

◆ Same level of reliability

The quality is same level by using IGBT rectifier as conventional SCR rectifier.

◆ Higher power factor in the whole range

◆ Lower output ripple

◆ Modular design

In case of one module is faulty, stop working won't affect other modules continue running and keep continuous operation of CED coating process

◆ Not affected by input voltage fluctuation

◆ Higher efficiency

◆ High regulation accuracy

◆ Fast response time

◆ Wide output voltage range

◆ Power saving

Through IGBT PWM technology, rectifier conversion efficiency is much higher than conventional SCR rectifier, thus saving power of user dramatically.
