Just found this video on the net . Looks like a robot spraying method, but This technology is different. The time taken to spray per piece is very small compared to other methods of spraying used in sanitaryware because the number of spray gun used at a time is more than the normal spraying method. Normally maximum two guns will be used in robot for spraying glaze and one more gun will be used for spraying water(optional). Manual loading and unloading is required for this kind of spraying.
