Varnish Plant in Pune, Maharashtra
SEW Surface Coating Pvt. Ltd. designs, manufactures and installs varnishing 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.
Varnish is a chemical used to insulate electrical goods such as motor windings, stators and transformer coils. A varnishing plant pre-heats the article in a moisture drying oven, dips it in varnish and then cures it in a varnish curing oven. Both ovens have solvent exhaust to maintain the LEL level.

Varnish 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 varnish plants comes mainly from automotive and component makers, appliance and HVAC makers and electrical and panel makers. Electrical windings must be free of moisture before they are varnished, and the varnish must be cured fully to give reliable insulation. Ovens with even air circulation and controlled temperature do both, batch after batch.
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.
Varnish Plant Equipment We Supply in Pune
Moisture Drying Oven
An enclosed insulated chamber with an air-circulating blower and electrical heater. It heats the article before it is dipped in varnish, so moisture is driven out of the winding.
- Air circulation for even temperature
- Electrical heating
- Solvent evaporation exhaust to maintain LEL level
Varnish Curing Oven
After dipping in varnish, the article travels through this oven for a set time so the varnish cures on it. The chamber has an air-circulating blower with electrical heater.
- Air circulation for even temperature
- Electrical heating
- Solvent evaporation exhaust to maintain LEL level
Typical Varnishing Process
A standard varnishing line follows this sequence:
- LoadingWindings, stators or coils are loaded on trays or the conveyor.
- Moisture DryingPre-heating drives moisture out of the winding.
- Varnish DippingThe hot article is dipped in varnish.
- DrainingExcess varnish drips off before curing.
- Varnish CuringThe article is baked until the varnish cures.
- Cooling & UnloadingParts cool and are inspected.
Oven size, temperature and residence time are set to your varnish type and the size of your windings.

Varnish Plant in Pune – Frequently Asked Questions
Are you a varnish plant manufacturer in Pune?
Yes. SEW Surface Coating Pvt. Ltd. manufactures varnish 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 a varnish plant used for?
It insulates electrical goods such as motor windings, stators and transformer coils. The plant pre-heats the article, dips it in varnish and cures the varnish in an oven.
Why is a moisture drying oven needed?
Windings absorb moisture. The moisture drying oven heats the article before dipping so moisture is driven out and the varnish penetrates and bonds properly.
Are the ovens safe for solvent-based varnish?
Yes. Both ovens have a solvent evaporation exhaust system that keeps solvent concentration below the lower explosive limit (LEL).
Do you make other special ovens?
Yes. We also build special purpose ovens up to 800°C for baking, bonding, stress relieving and annealing.
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.
