HY-K092 Experimental electrostatic powder coating machine for material testing and process development

The experimental electrostatic powder coating machine is mainly used for small-scale spraying tests or sample preparation in laboratory environments. Its core function is to accurately control the spraying parameters and adapt to diverse experimental needs. The following are the main characteristics and selection references of this type of equipment:

1. Equipment type and structure
‌Handheld spray gun‌
Equipped with a built-in/external high-voltage generator, the powder is charged and adsorbed to the surface of the workpiece through corona discharge.
Some models support remote controllers and display screens, which are convenient for real-time adjustment of parameters such as current, voltage, and atomization volume.
‌Powder supply system‌
Powder barrels or vibrating screens are used for powder supply, and powder pumps (such as Venturi or HDLV types) convey powder to the spray gun to ensure continuous and stable feeding.
The small powder barrel capacity is suitable for frequent powder change needs in laboratories, and some models support fast color change function.

2. Process advantages
‌Precise control‌
The digital control circuit realizes closed-loop regulation (such as iFlow flow control, AFC current feedback) to ensure coating uniformity.
It can form a thin coating of 0.5-5mil, and the thickness can reach 20-25mil after heating the workpiece. 6.
‌Environmentally friendly and efficient‌
No VOC emissions, powder recovery rate is as high as 95% or more, which meets the environmental protection requirements of the laboratory.
Electrostatic adsorption reduces powder waste and is suitable for small batch and high-precision experimental needs.

III. Applicable scenarios
‌Material testing‌: Verify the adhesion, corrosion resistance and other properties of powder coatings and substrates.
‌Process development‌: Optimize spraying parameters (such as voltage, atomization pressure) to simulate industrial production conditions.

‌Teaching demonstration‌: Intuitively show the principle of electrostatic spraying and the leveling and curing process of powder.
