Kovolak s.r.o., painting shop with liquid paint

For the company Kovolak s.r.o., which was the general supplier of the entire paint shop, we delivered a paint shop transport system based on the Power and Free principle, complete water management, chamber spray degreasing machine and water dryer, as well as paint dryer, to the newly built paint shop of CHARVÁT STROJÁRNE a.s.

The Power and Free transport system works in stop and go mode. This variant of the transport system was chosen with regard to the future use of robotic painting, as well as due to the large weight of painted parts.

A chamber spraying machine was installed to prepare the surface of the parts, which performs three operations - combined degreasing and Fe-phosphating, a single-stage circulating rinse and a final rinse from the frame with fresh demineralized water. DI water is produced in a DI water production station with the help of reverse osmosis. Wastewater from the spray chamber machine is treated in the supplied wastewater treatment plant before being discharged into the sewer system.

After preparing the surface of the parts in the chamber spraying machine, the water is dried with hot air. After drying the surface of the parts before the actual cooling of the parts, there is a possibility of manual blowing of the parts in order to remove water from hard-to-reach places of the parts.

Painting is currently done manually, in front of a suction wall with a dry three-layer filtration system. There are two painting workplaces on the line for applying a total of two coats of paint in one pass through the line. Each painting station is followed by a paint dryer and a cooling zone. In the painting position, it is possible to rotate the suspended parts according to their vertical axis.

The entire painting line is controlled by a control system with visualization and the possibility of remote access.
