Manufacturing Line
 

VIL's Colour Coating Plant is fully imported unit, with the latest technology having 140 metres length and designed with the latest Two Coat Two Bake System, with an accumulator at each end. The Primer and Top Coat are applied in the same run, leading to Zero Wastage of Coils. Two Reverse Roller Coating Machines ensure uniformity, quality and performance of the paint system. Each machine is capable of coating the front and back, and can be used to coat four colours in one run to provide Two Side Coating (C2S) for special customer requirements.

The distinct advantage of the coil coating process is its ability to provide a uniform coating with very reproducible thickness, colour and glass, in order to achieve better life and aesthetics.
