Automatic metal surface powder coating production line

The process flow of the coating production line is divided into: pretreatment, powder coating, heating and curing. There are manual simple process and automatic pre-treatment process before the production process in the early stage, and the latter is divided into two processes: automatic spraying and automatic dip spraying.
The workpiece must be surface treated to remove oil and rust before dusting. There are many chemicals used in this section, mainly including rust remover, degreaser, surface adjuster, phosphating agent and so on. In the pre-processing section or workshop of the coating production line, the first thing to pay attention to is to formulate the necessary systems for the purchase, transportation, storage and use of strong acids and alkalis, to provide workers with the necessary protective clothing, safe and reliable dressing, handling, and configuration equipment, and Develop emergency measures and rescue measures in the event of an accident.
Secondly, in the pre-treatment section of the coating production line, due to the existence of a certain amount of waste gas, waste liquid and other three wastes, in terms of environmental protection measures, it is necessary to configure exhaust gas, liquid drainage and three waste treatment devices. The quality of the pre-treated workpieces should be different due to the different process flow of the pre-treatment liquid and the coating production line. For workpieces that are well treated, the surface oil and rust are completely removed. In order to prevent rusting again in a short period of time, phosphating or passivation treatment should generally be carried out in several processes after pre-treatment:
Before powder spraying, the phosphated workpiece should also be dried to remove its surface moisture. Small batches of single-piece production, generally use natural drying, sun-drying, and air-drying. For large-volume flow operations, low-temperature drying is generally adopted, and an oven or drying tunnel is used.

Metal Surface Powder Spraying Production Line

The small cyclone + filter element recovery device in powder spraying is a more advanced powder recovery device with faster color change. The key part of the powder spray system is recommended to use imported products, and the powder spray room, electric mechanical lift and other parts are all made in China.

Applicable to metal products Automatic Powder Coating Line is mainly used for metal coating, such as aluminum profiles, drum hardware, auto, bicycle parts, etc.It is often used to create a harder finish than traditional paint.The main difference between traditional liquid coatings and powder coatings is that powder coatings do not require solvents to keep the binder and filler in liquid suspension.The coating is usually applied electrostatically and then cured under heat, allowing it to flow and form a "skin".Small equipment investment, meet the requirements of powder spraying of low-output workpiece.

In addition to Metal Surface Powder Spraying Production Line, our Surface Treatment Production Line series includes Surface Painting Production Line and Cleaning And Oxidation Production Line, which can meet various surface treatment processes required for production.
