CED Coating Plant in Pune, Maharashtra
SEW Surface Coating Pvt. Ltd. designs, manufactures and installs CED (cathodic electro-deposition) coating plants for manufacturers in Pune. Our factory is right here in Pune district, at Ranje on Kondhanpur Road, so Pune buyers deal directly with the manufacturer, with no dealer in between.
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.

- UF Paint Recovery
- 1200+ hrs Salt Spray

CED Coating Plants for Pune's Manufacturing Industry
Pune is one of India's largest automotive and engineering centres. Vehicle and component plants are concentrated in Chakan, Bhosari, Pimpri-Chinchwad and Talegaon. Appliance and engineering units have grown in Ranjangaon, Sanaswadi and Shikrapur, and newer industrial belts are coming up along the Pune–Satara road at Shirwal and Khed Shivapur.
In Pune, demand for CED coating plants comes mainly from automotive and component makers, appliance and HVAC makers and electrical and panel 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.
For a Pune buyer, having the manufacturer in the same district is a practical advantage. You can visit our works at Ranje to see equipment under fabrication, our engineers can reach your site quickly for layout studies, and service support is close by after commissioning.
Types of CED Coating Plants We Supply in Pune
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 Pune – Frequently Asked Questions
Are you a CED coating plant manufacturer in Pune?
Yes. SEW Surface Coating Pvt. Ltd. manufactures CED coating plants at its own factory at Ranje, Kondhanpur Road, Pune, and has been doing so since 1996. We supply, erect and commission them for customers across Pune and the rest of India.
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.
Can I visit your factory before ordering?
Yes. Our works is in Pune district, so Pune customers can visit us to discuss the layout and see equipment under fabrication. Call +91-99758 35066 to arrange a visit.
