The automatic powder coating machine has several spraying methods, such as 1. Electrostatic spraying method: it is the most commonly used spraying method for powder automatic spraying equipment, mainly through the electrostatic field to make the electrostatic powder coating evenly fall on the surface of the workpiece to be sprayed, A uniform coating is then formed by leveling in a curing oven; 2. Electrostatic fluidized bed spraying method: The electrostatic fluidized bed spraying method is mainly by adding high-voltage electrodes to the interval of the porous plate at the bottom of the powder automatic spraying equipment and the container. Thus, a high-voltage electric field is formed between the piezo electrode and the workpiece, and the uniformity and adhesion of the coating thickness of the powder coating are greatly improved; 3. Electrostatic oscillating powder coating method: The electrostatic oscillating powder coating method used in powder coatng machine mainly converts the high-voltage point of direct current into a high-voltage electrostatic field, so that its periodic change produces electric field oscillation. And under the action of this oscillating electrostatic field, the powder coating will float.

Electrostatic powder coating gun is mainly composed of powder supply barrel, powder spray gun and controller. It is a special spray gun for electrostatic spraying 

The temperature deviation in the powder coating oven is small. The disadvantage is that the heating time is slow and the equipment power is large, and it is not fit for used as an industrial powder coating oven. Because it is heated by hot air circulation, the curing process is easy to cause secondary pollution of dust. The furnace occupies a large area. The advantages of the gas-fired direct heating method are fast heating speed, high heat energy conversion rate, proportional adjustment control for furnace temperature control, and small temperature control deviation in the warm furnace. Because the burner flame burns directly in the combustion chamber, the curing process is likely to cause secondary pollution of dust and exhaust gas, which is not suitable for use as a home powder coating oven. A high temperature resistant filter should be installed in the heating chamber, so that the full pressure of the circulating fan should be considered in the selection of the fan. In addition, the heating indoor plate must be made of stainless steel plate, the cost of these two equipment is relatively Increase, the furnace covers a large area.

Powder coating filter is a kind of multi-purpose filter equipment with novel structure, small size, simple and flexible operation, energy saving, high efficiency, airtight work and strong adaptability. It is a pressure filter device. The liquid flows into the filter bag fromThe main recovery methods of powder coating include filter element recovery and combination of large cyclone and small cyclone. Improvements to the powder coating recovery powder sieve system allow for a more efficient, cleaner coating. 1. Filter element detection
