What Are the Equipment Components in the Coating Production Line?

The seven major components of the coating production line mainly include: pretreatment equipment, powder spraying system, paint spraying equipment, oven, heat source system, electric control system, suspension conveyor chain, etc.


1. Pretreatment equipment for coating production line

The spray type multi-station pretreatment unit is a commonly used equipment for surface treatment. Its principle is to use mechanical scouring to accelerate chemical reactions to complete the process of degreasing, phosphating, and water washing. The typical process of spray pretreatment of steel parts is pre-degreasing, degreasing, water washing, water washing, surface conditioning, phosphating, water washing, water washing, pure water washing. The pre-treatment can also use a shot blasting machine, which is suitable for steel parts with simple structure, severe corrosion, and oil-free or low-oil. And there is no water pollution.


2. Powder spraying system for coating production line

The small cyclone plus filter element recovery device in powder spraying is a more advanced powder recovery device with faster color change.


3. Painting equipment for painting production line

Such as oil spray paint booths and water curtain spray booths are widely used in the surface coating of bicycles, automobile leaf springs, and large loaders.


4. Heat source system for coating production line

Hot air circulation is a common heating method, which uses the principle of convection conduction to heat the oven to dry and solidify the workpiece. The heat source can be selected according to the user's specific situation: electricity, steam, gas or oil, etc. The heat source box can be determined according to the situation of the oven: placed on the top, bottom, and sides. If the circulating fan that produces the heat source is a special high-temperature resistant fan, it has the advantages of long life, low energy consumption, low noise, and small size.


5. Electronic control system for coating production line

The electrical control of the coating production line has centralized and single-row control. Centralized control can use a programmable controller to control the host, automatically control each process, data collection, and monitor and alarm according to the programmed control program. Single-line control is the most commonly used control method in the coating production line. Each process is controlled in a single-line manner. The electric control box is set near the equipment, which has low cost, intuitive operation, and convenient maintenance.
