Normally, the investment cost of painting lines will be quite high if foreign car paint partners are selected. The large cost, in addition to the reason for the brainpower and modern technology, is also due to the costs of the experts (accommodation, work, training, operation, maintenance …), the cost of imported equipment and materials, customs procedures, transportation … If choosing domestic contractors to cooperate, the costs will be cut significantly.

Basic process of an automobile painting line

Painting a car is not as easy as you would find the staff members at the garage you used to be. You can’t just grab a brush and scrub the surface and start painting your car. You have to prepare and carry out a lot of steps before you start painting your car. We will talk about all the steps required to paint a car. Of course, depending on how paint companies’ paint process is built and paint requirements, capacity, vehicle model number and level of automation of customers, some stages in the paint line may be combed. remove or combine in other stages, or add. Accordingly, the backend systems can be simplified. But basically the painting process includes the following steps:

quy trinh son o to day chuyen son o to CNC-VINA

The chassis goes through the Pre-Treatment line and is painted with ED paint (E-coat)

The process of cleaning and painting ED is carried out by a system of steel tanks, stainless steel tanks with a volume of several tens to several hundred m3 / tank-PT&ED line has a circulating pump system to filter paint and control the specifications.

The first station in the painting process is the pretreatment, where the tires that pass through the paint shop are cleaned, heated, degreased and often phosphate on the surface in preparation for the next coating. The second step of the process is electrostatic-ED coating, which is coated with a corrosion-resistant primer by immersing the tank in a conductive tank. To ensure that the interior is also properly disposed of, the trunk is soaked during the process.

Here, the frame from the hull welding workshop moves on a dolly or transverse chain conveyor, the conveyor that attaches the hull jig is brought into position in front of the line, grabbed by a crane system and dipped through the tank or item the mounting on the conveyor belt rotates 180 degrees to dip the tire into the tank. During all stages of the paint line, the body is placed on the trolley-attached fixtures on the propeller rail or programmed floor conveyor or hanger conveyor.

Traditional ED coating technology has been used in the automotive industry for many years with FRP-coated dipping tanks and anode electrode plates. The pre-treatment and electrostatic coating technology with Ecopaint WetSystem is based on the advanced and flexible technology being applied by Durr, a German car paint company, for new automotive paint lines.

Painting a car requires a suitable environment, free of ambient dust and high humidity. Chemical tanks, DI water always need to be controlled with indicators of temperature, humidity, bacteria, PH … to ensure the best ED paint.

The layer of ED paint for car chassis is the coating that determines the durability of the bodywork. During use, the decorative paint you see on the outside can be scratched, destroying the interior frame. If the ED painting process is not good, vehicle structure will be affected, causing unsafety during use. This is not allowed. It protects the vehicle from corrosion, especially the body cavities which cannot be easily accessed by the spray paint method.

Furthermore, the quality of ED paint affecting the painting process of Primer and Top Coat will be discussed below.

Dry the ED paint in the oven

Electrostatic ED coating on the car body after coming out of the paint tank is dried ED in the Oven hot air oven can be up to 150 degrees Celsius. control by vehicle model. Oven is powered by a heating system – a gas or oil burner. At the end of the oven, there is a fan cooling system to help reduce the body temperature before going to the next stage.

Polishing, filling pump for undercarriage, sound absorption

In this stage, unsatisfactory paints will be polished by sanding machines in the polishing room. Next, the car body will be taken to the sealing area, sealant and sprayed PVC undercarriage, sound damper before going to the next stage.

Paint primer and top coat in paint booths and dry in the oven

These are spray painting stages in spray painting where temperature, humidity, and light are controlled. Paint by human or robotic arms with the aid of mixing systems, paint dusting, air conditioning systems, ventilation …

Primer Paint Primer paint smooths the existing surface of the ED primer coat, protects the primer primer against rust and and increases the adhesion between coats, helping to detect any substrate irregularities and possibly sanded easily.

Paint Top coat with a basecoat and clearcoat painting stage. These two painting steps are basically the same, only differ in technical requirements due to the use of the substrate and the outer coating. After each stage is finished, the tires are put into the oven at high temperature before moving to the next stage. Top coat painting usually has 2 stages: base coat and clear coat.

Base coat: gives the main color to the body of the car, so it plays an important role in making the visual impression on customers.

Clear coat: painted at the end. It protects the car from external factors such as rain, sun, snow, UV radiation, dust …

Repairs may be interwoven in the surrounding work zone cubicle areas.

Refer to the thickness of the layers of paint (human hair is 0.1 millimeters = 100 µm)

ED: 17-22 µm

Primer: 30-35 µm

Basecoat: 10-20 µm

Clearcoat 30-50 µm

Inspection, Repair, Wax, Spot repair before moving to the assembly line.

Inspection, Repair, Wax, Spot repair – These are the final stages of the automotive coating line. Currently, this stage is still mainly using humans with the help of equipment or collaborative robots.

In addition, the automobile and motorcycle manufacturing and assembling factories may have more plastic paint lines to help paint plastic details and bumper for complete vehicle assembly.

The systems and equipment in the car painting line

Car painting line is a sequential line requiring each stage to always ensure quality so as not to affect the next stage. Therefore, in addition to the main system, the backend system also plays a very important role in the chain.

Systems and equipment in the automotive painting line include:

Coating system PT-ED. Oil tanks, tanks, chemicals, paint dipping tanks…

DI, RO water supply system, hot water supply Boiler, cooling chiller, wastewater treatment system, weekly pump system, UF filter system…

Plastic coating system

Conveyor systems, Conveyor systems, lifting systems (hoist, cranes)

Oven after each painting step. Combustion chamber system with gas burner, burner oil burner for fuel from oil station, LPG station.

Paint removal system, line, JIG…

Area of ​​spraying, polishing and repairing chambers (Work zone)
