Varnish Plant in Hosur, Tamil Nadu
SEW Surface Coating Pvt. Ltd. designs, manufactures and installs varnishing plants for manufacturers in Hosur, Tamil Nadu. Every plant is built at our own works in Pune, Maharashtra, then erected and commissioned at your site in Hosur.
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 Hosur's Manufacturing Industry
Hosur, on the Tamil Nadu–Karnataka border, is a major auto and engineering town. SIPCOT I and II host two-wheeler, commercial-vehicle and component plants, and the Shoolagiri and Krishnagiri belt is adding new electric-vehicle and electronics investment.
In Hosur, demand for varnish plants comes mainly from automotive and component makers, engineering and fabrication units 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.
Tier-1 and tier-2 suppliers in Hosur run high-volume finishing lines for OEMs. Hosur is about 880 km from our Pune works by road.
Varnish Plant Equipment We Supply in Hosur
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 Hosur – Frequently Asked Questions
Do you supply varnish plants in Hosur?
Yes. SEW Surface Coating Pvt. Ltd. manufactures varnish plants at its factory in Pune and supplies, erects and commissions them for customers across Hosur, Tamil Nadu.
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.
How is the plant delivered and installed in Hosur?
The plant is fabricated at our Pune works, about 880 km from Hosur by road. It is dispatched to your site, where our team erects and commissions it and carries out trial runs.
