ElectroStatic Powder Coating is considered as a coating that protects chassis parts of trailers from external influences such as weather or light scratches. Thanks to many outstanding advantages, ElectroStatic Powder Coating is widely popular in production in many different industries and the field of trailer production as well. Tan Thanh Company - a company specializing in production of containers and trailers, has installed an ElectroStatic Powder Coating system, automatic ball injection and high-tech durable autoclave. With imported machinery, this system has created many beautiful products with very high durability, saving a lot of costs for the market and especially friendly with the environment. Let's explore what is special about the process of painting the trailer with modern technology at Tan Thanh factory.
The advanced semi trailer paint factory of Tan Thanh Company
Tan Thanh semi-trailer products have to undergo a 3-step painting process to make the paint layer highly aesthetic and durable. The semi-trailer painting process at Tan Thanh factory owns an automatic chain conveyor that is used to move products easily during the painting process from the ball spraying system, through the automatic electrostatic spraying machine and finally the movement to the drying room. In addition, they are equipped with modern control systems with automatic sensors. Here are details of the three steps to painting a trailer.
Step 01: Ball spray to clean the chassis surface by automatic ball injection system
The first step in the painting process is that trailers are fed into the automatic ball injection system. The ball injection system helps to clean the chassis surface, helps to create the surface roughness and the necessary shape of the chassis surface so that the coating can adhere more firmly. Moreover, the chassis layer after spraying also becomes more durable, which reduces the risk of damage caused by external impacts and the combined mechanical corrosion from the inside. The products, after spraying, will reach the cleanliness according to international standards up to SA2/SA2.5.
Step 02: Apply powder coating by automatic electrostatic spraying system
The cleaning product after being sprayed will be moved through the automatic electrostatic paint system with 16 paint spray guns. With a semi-trailer about 12m long, the process will only take about 16 minutes to automatically paint. Tan Thanh's powder coating room is capable of sealing almost the entire surface area of the product. With coverage, up to 99% of the product surface is painted. Sites that cannot be automatically powder coated will be hand-painted using premium 2-component paint for maximum protection.
Main structure of Tan Thanh ElectroStatic Powder Coating system
Tan Thanh's automatic electrostatic spraying system includes: 1 automatic ball injection machine, a manual ball spraying chamber, powder coating spraying chamber with 2 paint spraying translator robots (each robot is fitted with 8 paint spray guns) and 2 paint spray guns, 1 oven, lower chain conveyor system, control system (sensors, control cabinet and signal light system, indicator lights). However, most of the Vietnamese enterprises have small and medium scale electrostatic spraying systems. With Tan Thanh, this system is invested heavily, and can be used with products up to 15m in length.
In addition, Tan Thanh Automatic ElectroStatic Powder Coating system has a closed Xyclon reclaimed paint system. The amount of powder coating dropped during the painting process is completely recovered and cleaned again, before being put back into the powder coating tank. As a result, the amount of paint emitted is very small, environmentally friendly, bringing high economic results. Meanwhile, the current technologies of water and oil painting are completely unable to recover this amount of paint waste, causing great harm to the environment because the paint waste is toxic and difficult to handle.
Tan Thanh uses AkzoNobel electrostatic powder coating
For products of great value and size such as the automatic electrostatic paint trailers, the products are more durable, save materials, save production time and they are highly appreciated for their eco-friendliness. Tan Thanh uses powder coating from AkzoNobel brand, which is the brand name for the world-renowned manufacturing industry from the Netherlands.
AkzoNobel electrostatic powder coating has absolute uniformity of color, gloss and durability across the entire product. For water and oil paints, the painted surface will give different color and gloss if there is a change in film thickness. Meanwhile, AkzoNobel electrostatic powder coating is completely unaffected by this.
Step 03: The drying process after painting with a modern drying room
The last step in the painting process, after finishing painting, the semi-finished products are moved to the drying room to dry. The system owns a drying room at the Tan Thanh semi-trailer factory with a large capacity, helping to dry quickly within 45 minutes, saving significant time for the painting process instead of having to wait for 1 to 2 days like types ordinary water paints, oil paints.
Paint drying room has the ability to reach 180 degrees C in 10 minutes. This is the condition for the entire surface of the product to fully ripen. After that, the product is taken out to wait for the cold and complete assembly process.
