Roller coating

All materials are. The only requirement is to have a flat surface.

Examples of products suitable for roller coating:

• cabinet doors
• parquet
• doors

Examples of materials suitable for roller coating:

• wood and wood-based materials
• glass
• cork
• plastic
• fibre cement
• metal
• roll-to-roll for edges etc.

High flexibility in terms of output rate and choice of cycles/processes according to the line make-up.

Zero solvent emissions thanks to 95% use of products with high dry residue (UV) content.

Possibility of using the roller technique for any application on all flat surfaces.

The quality of the paint finish is highly subjective. However, opacity and gloss, and obviously, the degree of application, can all be rated.

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.

Yes. It often happens to have coating lines consisting of roller coating machines for primer/insulating product application followed by spray coating machines for finishing.

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.

An automatic system is being developed, designed to monitor the parameters relating to the consumption of coating products also in roller coating machines. 

The number of operators required for the correct operation of a roller coating line depends on the complexity and length of the line. We can reasonably expect that 2-3 people will be needed to work on the line.

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.

No. The most delicate part is the rubber roller which will have to be surface-ground or re-coated. There are also normal wear parts that need to be replaced: scrapers, pumps, etc.

Our international network of distributors and branch facilities is widespread globally, and most likely, you'll easily find the right contact in your own country. Otherwise, in just a few days we will send spare parts and technicians straight from our headquarters.

Roller coating machines can only coat flat surfaces. There are some special cases in which a special machine with a soft roller can be used to coat bevelled parts, too. This is the case for example with the beveled side of parquet flooring, where the bevel reaches up to 4 mm.

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.

Downstream from each roller painting machine, a gelling/drying oven is needed. It can be either a UV or a hot air oven according to the type of coat applied. In addition, machines for sanding primer coats, brushing machines for cleaning the panels and conveying machines along the line are needed.

On roller coating lines, it is quite simple. Depending on the output demand, we can calculate the line speed and then decide how many UV lamps are needed to be able to gel or dry the finish coats at that precise speed. This helps to respond effectively to required changes in output rate.

The machines are flexible both in terms of product quantities to be applied, and in terms of versatiliy - being suitable for different applications, at various locations along the line.

In roller coating machines, 100% UV acrylic products, as well as water-based products, can be used resulting in a highly sustainable finishing process.

Yes. Normally, on small, low-output lines, the machines are flushed to carry out colour changeover. Otherwise, multipurpose machines are added to the lines to be able to manage colour changes very quickly.

In this respect, a roller coating line ensures maximum flexibility. It enables to process any panel shape, also in random order - as long as all the panels have the same thickness.

Yes. A whole range of UBIQUO service packages is available for this equipment as well as for other finishing solutions.
