Coating product consumption and consumption of solvents required for cleaning the machines in the coating line should certainly be considered and evaluated. Each step of the roller coating process must be monitored in terms of the quantity applied, for each individual machine. Quantities, in fact, may vary according to the type of substrate treated.
Today, thanks to the SmartCoater PRO series and the choice of specially designed rollers, in some cases it is possible to apply UV primers on cabinet doors and specially shaped doors. This refers to primer application. After the intermediate sanding phase, finishing is carried out with spray coating machines.
The average time required to clean a roller coating machine was 20 minutes. A critical variable was the use of clear or pigmented coats. Today, with our new semi-automatic system, considerably less time is needed for an operator to carry out cleaning. Additionally, the consumption of solvents is heavily reduced, with resulting advantages in terms of efficiency and sustainability also in the roller coating process.
Lamination and roller coating are two different processes. A coated product is generally considered more sophisticated than a product laminated with paper or plastic film. Laminating a panel is practical when we have to process small production batches.
Roller coating, on the other hand, is definitely more cost-effective to treat matt or glossy methacrylate sheets.
Thanks to roller coating technologies, various degrees of finish can be obtained, either clear or pigmented, matt, semi-gloss or glossy. Additionally, since the roller lines are made up of a number of applications, aluminium dioxide- or corundum-based coats can be applied in order to achieve high surface abrasion strength.
