Wet Painting Plans for Plastic, Wood and Various Materials
Deciding about the plant that will meet your demands relay on your budget, the space you dedicate for the plant installation, your production capacity, weight and the dimensions of the items to be painted.
According to method of operation, Painting Systems can be divided into 4 main groups;
1- Manual Systems
2- Semi-Automatic Systems
3- Automatic Systems
4- PLC Controlled Full Automatic Systems
1- Manual Wet Painting Systems are Water Based Units
a- Pretreatment
Cleaning and preparing the items for painting is depending on the materials they are made from.
b- Drying
Generally there is no need for drying oven for these kinds of materials; the environment temperature is enough to dry them.
c- Manual Trolleys and Material Carrying Rays
After items are cleaned and dried they are loaded to the manual trolleys or hanged to the manual aerial conveyor taking their way to the booth for paint application and after that to the curing oven. Special design pallets also are used in manual systems which called Station Type. In this system there is pallet chain with three stations above the curing oven. The pallet chain can be run a stopped manually. Items are hanged to the conveyor in front of the oven waiting for the other items to be cured. After a group of items is cured the pallet chain is run. While the cured group is moving out other group is moving into the oven. And while this group of items is been cured other group is hanged in front of the oven preparing for the next turn and so.
d- Manual Wet Painting Booth
Generally wet paint application booths are water based manufactured. But also they can be divided into two main groups:
· Wet Paint Application Booths with Water Screen
· Wet Paint Application Booths with Dry Filter Group
Both types are front opened or can be also positive pressure based manufactured. Upon request, in positive pressure based type booths paint application can be under pre-adjusted environment conditions. For example; air-condition facility can be added to the booth which will maintain the inner environment according to the pre-adjusted temperature or humidity values.
Working principles of the Wet Paint Application Booths with Water Screen
Items are taken manually to the painting booth. Paint is applied manually or using some special type robots. While air is sucked from the booth with 0.3 – 0.5 m/sec remaining paint is filtered through the water screen and delivered out of the factory.
There is a liquid tank at the bottom of the booth for the of water and chemicals mix. This mix is sucked from the tank and delivered to upper side of the booth passing by the pool of the water screen to the nozzles at the air screen area. Water flows as a thin band from the tank above forming a screen which delivers the remaining paint to the collecting tank at the bottom of the booth. At the back of the booth there are special designed nozzles that scan the circulated air and clean it from the escaped paint particles delivering them to the collecting tank. The remaining paint takes sponge shape after treated by the mix of water and chemicals and float over the water; so it is collected from the water while cleaning the tank.
After painting the items need to be flashed-off to evaporate the solvent within the paint. This flash-off time shows changes according to the used paint. Upon request this operation can be inside the painting booth or in well ventilated separate room.
Working principles of the Wet Paint Application Booths with Dry Type Filters
Items are taken manually to the painting booth. Paint is applied manually or using some special type robots. While air is sucked from the booth with 0.3 – 0.5 m/sec remaining paint is held using dry type filters delivered out of the factory.
There are dry type filters at the front or at the bottom of the booth. The sucked air from the booth passes through these filters that hold the remaining paint particles. Filters can be changed periodically to set the filtration system stable.

e- Manual Cuing Ovens
This type of ovens is designed one or double side closed. Indirect type combustion system is used on these ovens, so LPG, Natural Gas and Diesel can be used safely without any fire hazard. Upon request, ovens also can be built electrically operated. The products we manufacture differ from project to other depending on customers’ needs, materials dimensions, capacity and to their financial limits. We are able to determine and supply customers with their demands after discussing the matter with them in details to specify the suitable project they are willing to achieve.
2- Semi-Automatic Systems
a- Pretreatment
Cleaning and preparing the items for painting is depending on the materials they are made from.
b- Drying
Generally there is no need for drying oven for these kinds of materials; the environment temperature is enough to dry them.
c- Automatic Aerial Line Conveyor
Automatic Aerial Line conveyors are used for carrying the items through the painting operation. Generally there are two main conveyor types; Cardan Milli and Webb type conveyors. Deciding whether to be Cardan Milli or Webb type is based on the items weight and specifications. If weight handled by a single hook of the conveyor is less than
d- Manual or Automatic Type PVDF Application Booths
Generally wet paint application booths are water based manufactured. But also they can be divided into two main groups:
· Wet Paint Application Booths with Water Screen
· Wet Paint Application Booths with Dry Filter Group

e- Tunnel, U Turn or Multi-Turns Type Continuous Curing Oven with Air Screen
Items are on their way to the oven after being PVDF coated. The oven door is open to take the painted items in while the air screen fan is acting to decrease heat loss to the minimum. According to the painted items the oven can be designed tunnel, u turn or multi turns type. Oven also can be heightened over platform so the oven inlet can be on the bottom. Indirect type combustion system is used on these ovens, so LPG, Natural Gas and Diesel can be used safely without any fire hazard. Upon request, ovens also can be built electric operated. In ovens there is no standard type because demands and capacity differs from a customer to the other. We are able to determine and supply customers with their demands after discussing the matter with them in details to specify the suitable project they are willing to achieve.
f- Material Cooling Tunnels
After items come out of the oven, when there is no enough space for natural cooling, a cooling tunnel is used in such cases. The cooling tunnel systems based on generating circulation inside the tunnel by sucking fresh air and blow it over the cured items, at the same time other aspirators will suck air from inside to outside the tunnel which will accelerate the items cooling. The tunnel’s length depends on the conveyor’s speed and how thick the cured items are. In some special cases, the air sucked from outside is cooled before blowing over the items.
g- Electrical Control Panel and Related Equipments
Electrical control panel is built closed to the plant to be reached easily. The control panel is equipped with standard elements like fuse, start/stop buttons, thermal switch and the short contact groups.Also main switch, amperometer and voltammeter exist in the control panel with failure indicators and siren. Indicators of the control panel light in green but when there is malfunction somewhere it turns into red and the siren is on. The thermometers or the thermostats of the ovens are also on the control panel. A diagram that shows the entire operations in the factory can be added to the control panel upon request. It installed complete so the customer doesn’t have to supply anything except the main electrical cable.

h- PLC SCADA Unit
The painting plant can be operated with the support of PLC SCADA unit that adapted to the electrical system. The entire system is computer controlled. From the start of the motors, malfunction mode, heating systems, temperature control and even the conveyor speed all are computer controlled. The system based on entering the needed data to the computer memory and the system will operate accordingly. In this system you will be able to control and operate retrospectively. For example if there is quality loss in an item that sold 3 months before you can retrieve the data within the estimated date of the item production to determine exactly which kind of error caused that problem.
