CED Coating Plant in Nagpur, Maharashtra
SEW Surface Coating Pvt. Ltd. designs, manufactures and installs CED (cathodic electro-deposition) coating plants for manufacturers in Nagpur, Maharashtra. Every plant is built at our own works in Pune, Maharashtra, then erected and commissioned at your site in Nagpur.
CED is a water-based primer coating used mostly in automotive paint shops. Charged paint particles move to the component (the cathode) under a direct current, so paint reaches every corner of complex shapes. Un-deposited paint is rinsed and recovered through ultra-filtration (UF), and the film becomes hard after baking.
- Batch & Conveyorised
- UF Paint Recovery
- 1200+ hrs Salt Spray
- Supplied across Nagpur
CED Coating Plants for Nagpur's Manufacturing Industry
Nagpur is central India's industrial and logistics hub. Butibori and Hingna MIDCs host engineering, steel, power equipment and food-processing units, and the MIHAN SEZ has added aerospace and engineering investment.
In Nagpur, demand for CED coating plants comes mainly from steel structure fabricators, engineering and fabrication units and agricultural equipment makers. CED primer gives uniform film thickness, full coverage inside box sections and sharp edges, and salt spray resistance of more than 1200 hours. Paint utilisation is close to 100 percent, and because the process is water-based it carries less fire risk than solvent coatings.
Steel structure, power equipment and fabrication industries in Vidarbha need heavy-duty coating and pretreatment lines. Nagpur is about 715 km from our Pune works and plants are delivered by road.
Types of CED Coating Plants We Supply in Nagpur
Batch Type (Dip Tanks)
Components are loaded in jigs and moved through dip tanks by hoist or PLC-controlled transporter.
Best for: Mixed components and medium volumes.
Continuous Conveyorised
An overhead conveyor carries parts through pretreatment, the CED tank, UF rinses and the baking oven without stopping.
Best for: High-volume automotive and component production.
Combination of Dip and Spray
Spray stages for cleaning and rinsing are combined with dip stages for phosphating and CED, to suit the part and output.
Best for: Lines that need both throughput and full coverage.
CED Coating Process Sequence
The CED process on our plants follows this sequence:
- LoadParts are hung on jigs or the conveyor.
- DegreaseRemoves oil and grease.
- Water Rinse 1 / 2Two rinses after degreasing.
- ActivationPrepares the surface for phosphating.
- PhosphateBuilds the conversion coating.
- DM Water Rinse 1 / 2Clean demineralised water rinses.
- CEDElectro-deposition of primer.
- UF 1 and UF 2Ultra-filtrate rinses recover un-deposited paint.
- DM Water Rinse 3Final rinse before baking.
- Baking OvenThe film is baked hard.
- UnloadParts are inspected and unloaded.
Fully automatic operation needs less manual effort and allows the film thickness to be controlled.
Advantages of CED Over Conventional Primer
Uniform coating
Controlled film thickness and better coverage on interior surfaces, complex shapes and sharp corners.
No runs or sags
No runs, sags or solvent boils, giving a consistent primer surface.
Corrosion resistance
Surface salt spray resistance lasts for more than 1200 hours.
About 100% paint utilisation
UF recovers un-deposited paint, which makes the process cost effective.
Safer and cleaner
Water-based process with less fire risk and fewer pollution and health hazards than solvent coatings.

CED Coating Plant in Nagpur – Frequently Asked Questions
Do you supply CED coating plants in Nagpur?
Yes. SEW Surface Coating Pvt. Ltd. manufactures CED coating plants at its factory in Pune and supplies, erects and commissions them for customers across Nagpur, Maharashtra.
What is CED coating?
Cathodic electro-deposition (CED) is a water-based primer coating. Charged paint particles move to the component under direct current, so paint reaches every corner, and the film becomes hard after baking.
What is the role of UF in a CED plant?
Ultra-filtration separates paint ingredients that do not form film and recovers un-deposited paint from the rinses, which gives close to 100 percent paint utilisation.
How much corrosion resistance does CED give?
The baked CED film gives surface salt spray resistance of more than 1200 hours.
Can the CED plant be automatic?
Yes. CED lines run on a PLC-controlled transporter or a continuous conveyor, with automatic operation and controlled film thickness.
How is the plant delivered and installed in Nagpur?
The plant is fabricated at our Pune works, about 715 km from Nagpur by road. It is dispatched to your site, where our team erects and commissions it and carries out trial runs.
