In today’s industry, protecting metal from corrosion and increasing its life has become the biggest need. For this purpose, an excellent technique is used which is called CED Coating. If you also want to know what CED Coating is and how its process works, then this blog is for you.
What is CED Coating? (CED Coating Full Form)
The full form of CED is – Cathodic Electro Deposition. It is also called Cathodic Electrodeposition Coating. This is an advanced technique in which coating is done on the metal surface with the help of electrically charged particles. This coating forms a strong, uniform and corrosion-resistant layer on the metal surface.
Today the use of CED Coating is increasing rapidly in automobiles, agriculture equipment, industrial machinery and construction tools.
Why is CED Coating Important?
- Protects metal from corrosion.
- Gives a uniform coating on the surface.
- Long-lasting finishing.
- Creates a strong base coat before painting.
- More advanced and eco-friendly than traditional painting or coating methods.
CED Coating Process – Step by Step
Now let us know how the CED coating process works. This process consists of several steps which are completed in a systematic manner.
- Pre-Treatment of Metal
In this step, the metal surface is cleaned thoroughly. Dust, oil, rust and any kind of dirt are removed so that the coating can stick well. - Degreasing
Metal parts are put in a degreasing solution so that the oil or grease present on their surface is completely removed. - Phosphating
Now phosphating is done on the metal surface. This is a chemical treatment which forms a protective layer on the metal. This increases both corrosion resistance and adhesion. - CED Bath (Main Process)
This is the real CED coating process.
The metal part is placed in the CED bath tank.
The tank contains electrically charged paint particles.
When current is applied, these particles get deposited on the metal surface and form a uniform layer. - Rinsing
After the CED bath, the parts are rinsed to remove extra material and get a smooth coating. - Baking / Curing
Finally, the coated parts are baked in an oven. This hardens the coating and bonds it strongly to the metal surface.
CED Plant Process
Now let’s talk about the CED plant process. In any CED plant, a complete coating line is set up which includes many tanks and equipment.
A standard CED plant process consists of:
- Pre-treatment tanks
- Degreasing tanks
- Phosphating tanks
- CED bath tank
- Rinsing tanks
- Baking oven
The entire process can also be run with the help of automatic systems and conveyor lines. This increases the production capacity and maintains consistency.
Advantages of CED Coating
- High Corrosion Resistance – This coating protects the metal from rust for a long time.
- Uniform Coating – A uniform layer is formed till every corner and edge.
- Environment Friendly – It does not cause pollution like solvent-based paints.
- Cost Effective – Long term maintenance is less.
- Strong Base Coat – This is the best base for future powder coating or painting.
Applications of CED Coating
- Automobile Industry – On body parts and accessories of vehicles.
- Agriculture Equipment – On tractors and farming tools.
- Industrial Machinery – On heavy machines and spare parts.
- Furniture & Fixtures – On metal furniture and components.
- Construction Industry – On gates, grills and construction tools.
Future of CED Coating
The way industries are moving towards eco-friendly and advanced solutions today, the demand for CED coating is going to increase further. Its durability, uniformity and environmental safety are making it the most important coating technology of the coming times.
Conclusion
Now you must have come to know what is CED coating and how it works. In short, the CED coating process is a modern technique that protects the metal from corrosion, makes it durable and provides a uniform surface. Whether it is automobile, agriculture equipment or industrial machinery – its use is increasing rapidly everywhere.
If you also want to protect your products from corrosion and give them a strong and long-lasting finish, then going through the CED plant process is the best option for you.
