When it comes to coating, there is a crucial point beyond all else, that of lacquer consumption.
This depends on the type of machine, the type of conveyor (paper or continuous belt) and the type of filtration (paper or water).
Differences relate to the degree of freedom, the type/number of movements they can make and the angles they can achieve.
With paper-based filtration, the filters must be replaced; water-based filtration requires no maintenance as the system continuously "self-cleans" during operation.
As with manual coating system, maintenance largely concerns the pump and spray guns (i.e. the coating application system).
In the case of a machine with continuous belt conveying, cleaning and retrieval system maintenance is also required.
Machines with water filtration will also require maintenance of the continuous filtration device.
In the case of oscillating spray machines, all you need to do is provide some parameters and, thanks to the incoming piece reading system, each piece is then coated according to the information entered.
With robots, different work modes are possible so it is necessary to define the way and the order in which you wish to execute strokes and whether to coat certain product parts or not. Programmed this way, each piece loaded and read by the reading system is automatically processed as per the saved information.
It is advisable to have a drying system connected to the machine. This ensures more consistent results. It also lowers the percentage of waste compared to simple air drying, which involves some risk of contamination. What's more, some finishes require special drying conditions (temperature, air speed) so an oven is definitely recommended where certain finishes are needed.
