Superfici Finishing Wood Intro
The document outlines the Valtorta brand's product line for the Elmag company, focusing on various coating solutions including roller coaters and spraying machines. It details the efficiency of different lacquering methods, such as high-solid content UV lacquer and robotic spraying systems, while discussing their applications in furniture and window frames finishing. The document also describes drying technologies used to expedite the lacquering process, including linear and vertical dryers.

- 3. ROLLER COATING Using theroller method, all types of lacquer can be applied on two-dimensional work-pieces as long as their viscosity is suitable. The thickness of the lacquer film to be applied can be determined by means of a finely adjustable doctor roller. By this method minimal quantities of lacquer up to over 100 g/sqm can be applied without lacquer wastage. With extremely simple machine setting, this technique allows lacquering work to be carried out at high feed speeds and with solvent-free UV lacquering systems. ROLLER COATING can only be ROLLER COATING is suitable for used to lacquer FLAT PANELS HIGH-SOLID CONTENT UV LACQUERS

- 5. UV CURING UV CURING UVcurable materials are hardened in seconds by means of highly intensive uv radiation. The power and the number of lamps are determined by the feed speed and the type of finishing material used. -5-
- 6. UV CURING The modularsystem guarantees the right solution for every need. The LABES reflector concentrates the radiation in a quite wide area, thus maintaining a high energy level at different distances from the lamps. The COLDCURE achieves an efficient polymerisation, while greatly reducing the temperature increase of the substrate. -6-

- 8. SPRAYING MACHINES SPRAYING Spraying isan extremly versatile coating system, suitable for lacquering both flat and profiled workpieces with the most various types of lacquer. -8-
- 9. SPRAYING MACHINES SPRAYING The electroniccontrol OPTISPRAY optimizes the spraying area, by individually programming the intervention of each gun. -9-
- 10. SPRAYING MACHINES SPRAYING The oversprayon the belt is reclaimed by the patented lacquer reclaiming system SCRAPE ON WET. - 10 -
- 11. ROBOTIC SPRAYING ROBOTIC SPRAYING Hightech spraying system with electronic control of the movement of the spraying arm, which repeats the programmed working cycle according to the size and shape of the workpiece detected at the machine infeed. - 11 -
- 12. ROBOTIC SPRAYING The sprayarm is normally equipped with more guns (up to 4) which spray the flat surfaces, and with one gun (with a special nozzle) which sprays the edges. The spraying robot has a 5 axes control: - arm longitudinal movement (X) - arm transversal movement (Y) - spraying height (Z) - arm rotation - gun positioning on the edges lengthwise crosswise vertical rotation edge gun positioning (X) (Y) (Z) - 12 -
- 13. FLAT DRYERS Our lineardryers include different types of dryers mainly used in case of short drying times. COUNTER-FLOW VENTILATION The air flow goes from the exit of the tunnel towards the infeed. Such laminar ventilation basically removes the solvent from the coated substrates and then exhausts it outside. AIR BLADE VENTILATION The air is blown through narrow openings placed crosswise to the panel feed. Some air is exhausted, some is recirculated. The air speed is up to 14 m/sec. AIR JET DRYER The air is blown at a very high speed through round nozzles uniformly distributed on the whole roof of the drying hood. The air speed is up to 25 m/sec. - 13 -
- 14. VERTICAL DRYERS Our verticaldryer CONTIVERT guarantees the right air speed and temperature according to the drying cycle and the finishing material used, while requiring only a minimum of space and energy. - 14 -
- 15. WINDOW FRAMES FINISHING Infrared drying systems (IR) •Used for impregnation and stain •Higher efficiency compared to hot air
- 16. WINDOW FRAMES FINISHING Application systems with reciprocators •Reciprocators with electronic detection of the pieces to optimize of the spraying process. •Electrostatic guns for a reduced lacquer consumption and a higher transfer efficiency. •Cabin with motorized belt for the overspray recovery.
- 17. WINDOW FRAMES FINISHING Application systems with cartesian and anthropomorphic robots •Suitable for high quality lacquering expecially in case of pigmented finishing. •Quick lacquer change (60 sec.) •Elimination of the Faraday shield effect. •Charge length up to 6 m. (cartesian robots)
