Is the place where the pieces that need to be painted are loaded on the belt conveyer. The plant was built in such a way that it can carry pieces with maximum weight of 120 kilograms and maximum proportions of 3500 * 2000 * 700 millimeters (L*H*l). The speed of the conveyor recommended by the manufacturer is 1.5 – 2 meters / minute (depending on the complexity of the piece). Based on this characteristic the other components of the plant were designed in order to confer the maxim productivity and an excellent quality of the obtained surfaces.

   Before painting the pieces we perform a special treatment of the surface. The manufacturer managed to obtain at a maxim working speed a surface treatment which gives to the finished products a good mechanical endurance and an excellent durability (as long as 400 hours in salt fog).
   By collaboration with Henkel Romania and using high quality products, on our plant can be performed surface treatments of iron, steel pieces, also chemically zinc pieces and aluminum alloy.

The steps of the surface pre-treatment:

State	Temperature	Time	Pressure
Phosphate – Degreasing	50-60 C	3 min	2 atm
Rinsing with running water	ambient	1 min	2 atm
Rinsing with demineralized recycled water	ambient	1 min	1,5 atm
Rinsing with demineralized virgin water	ambient	nr.2	1,5 atm

   After passing through the pre-treatment tunnel the pieces carried by the conveyor will bear immediately a forced drying. They will pass through the drying oven for 10 minutes at 120 0 C.

   After leaving the forced drying oven, the pieces cool down naturaly. After that they enter the powder coating booth. Here the painting process is executed with powder coating by 8 spray guns (4 on the left / 4 on the right) manufactured by the Italian company Zeus Electrostatic System. The spray guns are installed on 2 automatic reciprocators. This technique gives a constant painting if we refer to the thickness of the paint layer and also we can obtain a reduced powder loss. The painting booth from our plant dispose of a cyclone powder collector for a fast recovery. This system helps us in quick powder exchange and we get less time lost in this process.
   The retouch of the pieces, if needed, is made by qualified personnel. They are permanently looking for to obtain well covered surfaces even in places that can create problems (the Faraday effect).

   After the pieces were powdered they will be carried by the conveyor in the polymerization oven. This bell-shaped oven ensures for a minimum 30 minutes period the optimum temperature for the powder to polymerize (usually 180 0 C).
   Because of the construction of this oven we can reach the needed temperatures (high temperatures) with a minimum expense of energy (gas). In this way we are able to obtain loe production costs.

   After the pieces descent from the polymerisation oven they cool at room temperature. Next they are un-loaded from the conveyor and a quality control of the surfaces takes place. Then the pieces can be packed on pallets deppending on the requirements of our clients. On request we can assamble and mount different parts of the pieces in order to obtain the finished products ready for expedition.
