Ticò’s painting plant for windows and doors is ready

Commercial relations with northern Italy are confirmed to be good. The last Finiture plant was built in Trento for Ticò Falegnameria. The painting process of the wooden windows starts from the loading-unloading area, where the operations are eased by an automatic pedal-operated lowering unit. Once hung, the pieces are carried by a double-hook point handling system. The workbenches are hinged to trolleys that move in the lower rail, while the tow chain runs on the upper one. Each bar is supported by two carriages to guarantee perfect stability even in case of large and not perfectly centered pieces. If necessary, the trolleys untangle from the chain, the rail doubles and the bars are arranged parallel to each other, forming an area for the accumulation and stop of the pieces.

The pieces pass through a "Superjet" tunnel, a dynamic impregnation system for moving parts in which the product is sprayed by three nozzle ramps. The excess part is collected in a tank and recirculated by pump. The hydraulic circuit consists of 4 valves for the delivery, suction, loading and unloading functions. Two other suitably positioned valves allow the complete emptying of the circuits after the washing phases.

Once impregnated, the profiles pass through the dry painting booth, where the initial over-spray recovery is operated by a honeycomb cardboard filter placed on the front of the cabin. The residual paint fumes are held by a glass fiber filter positioned behind the cardboard filter.

A heat-recovery compensator reintegrates the air expelled from the spray booths with extracted air from the outside, suitably filtered and, if necessary, heated. The heat exchanger transfers part of the heat of the expelled air to the cold inlet. The pre-heated air is then further raised by means of a hot water coil until it reaches the internal temperature of the building, but with considerable energy savings.

Finally, the pieces pass through a drying tunnel with LDP system and axial fans for drying products painted with water. The LDP system extracts moisture and accelerates drying times. Closed circuit air movement leads to significant energy savings and reduces installation costs, since it is not necessary to expel the air outside.

Water recovery is operated through a washing water clarifier. Dirty water is introduced into the upper tank where the flocculation process takes place. The opening of a manual valve makes the water fall into a filter where solid residues are deposited. The clarified and filtered water flows into a tank, from where it can be withdrawn and reused for washing.
