Haztek AG20 Automatic Powder Spray Gun

AG20 Automatic Spray Gun

TBuilt-in 100kV high-performance voltage-doubling block ensures stable continuous output, thereby achieving an extremely high powder deposition rate. The electrode needle features an internal triple air intake technology, which keeps the electrode needle tip clean, effectively preventing powder agglomeration and ensuring excellent electrostatic discharge effect. Elbow nozzles with various angles (90°, 120°, 135°) are available. It is compatible with most common powders, including metal powders, meeting various coating requirements and catering to diverse needs.

The AG20 Automatic Electrostatic Powder Spray Gun outperforms other domestic brands in an  all-round way in terms of internal structural design, electric field control system, and powder  delivery technology, while matching the performance of high-end European and American  spraying equipment in multiple key performance indicators (KPIs). Manufactured to extremely  high process standards, the spray gun selects core components from world-class brands,  boasting longer service life and higher stability; its precise voltage and current control as well as  modular structural design enable it to demonstrate outstanding adaptability and consistency in  coating operations for complex structures such as flat surfaces, grooves, and irregular shapes.

Modular structural design / More secure and stable

Multi-angle elbow nozzle (90°, 120°, 180°) meets various application scenarios

100kV high-performance booster module / extremely high powder deposition rate and coating coverage

International brand accessories / Static release more stable, durable and non-degrading

Electrode needle self-cleaning / three-time intake technology

The internal design of the spray gun features three cleaning gas channels, which can continuously clean the electrode needle tip, effectively preventing powder condensation, thereby ensuring excellent electrostatic release. This helps to improve the charging efficiency and powder application rate of the powder, thus enhancing the coating efficiency. At the same time, a clean electrode needle aids in sustained and non-decaying electrostatic release, allowing for more stable and thorough charging of the powder.

Millijoule Energy Control System

The system is built-in with an advanced "Hao Jiao Energy Control System". When the distance between the workpiece and the spray gun is below the preset safe distance, the output voltage of the spray gun will automatically decrease adaptively, effectively avoiding the phenomena of arc and sparking caused by excessive current, ensuring the safety of operation and production.

Two installation methods: base installation and integrated extension rod.

Integrated extension rod installation: The cable is wrapped inside the tube, which has good sealing properties, is less prone to accumulate dust, and can effectively avoid dust interference and aging, making the equipment more stable.

Base installation: easy to install, simple to maintain, and high cost-performance.

What Is an Electrostatic Powder Coating Line?

An Electrostatic Powder Coating Line is an advanced surface finishing system that uses electrostatic charging technology to apply powder coatings onto metal parts. The charged powder particles adhere evenly to grounded workpieces and are then cured in a high-temperature oven, forming a durable, smooth, and attractive finish.

1.A complete Haztek Powder Coating Line typically includes:

Pre-treatment System – cleans, degreases, and prepares the metal surface for coating.

2.Powder Spray Booth – equipped with manual or automatic electrostatic spray guns for uniform powder application.

3.Curing Oven – melts and solidifies the coating to achieve strong adhesion and corrosion resistance.

4.Conveyor & Reciprocator System – ensures continuous and efficient part movement.

5.Intelligent Control System – synchronizes all components for stable, energy-efficient operation.

Haztek's electrostatic powder coating lines deliver high transfer efficiency, minimal powder waste, and long-lasting coating performance, making them ideal for aluminum profiles, automotive parts, home appliances, and metal furniture.

Benefits of Electrostatic Powder Coating Line

An Electrostatic Powder Coating Line offers numerous advantages over traditional wet painting or manual coating methods. Designed for efficiency, sustainability, and superior finish quality, it helps manufacturers achieve higher productivity and lower operational costs.

Key Benefits:

1.High Transfer Efficiency – Electrostatic attraction ensures more powder adheres to the part, reducing material waste.

2.Durable and Uniform Finish – Produces a consistent coating with excellent adhesion, corrosion resistance, and impact strength.

3.Environmentally Friendly – 100% solvent-free process with minimal VOC emissions and recyclable overspray powder.

4.Low Maintenance and Easy Cleaning – Automated systems reduce downtime and simplify color changes.

5.Energy-Efficient Operation – Optimized curing ovens and intelligent control systems lower power consumption.

6.Cost-Effective Production – Less powder waste, reduced labor, and shorter curing times increase overall profitability.

7.Wide Application Range – Suitable for coating aluminum profiles, automotive parts, steel furniture, home appliances, and more.

With Haztek’s automatic electrostatic powder coating solutions, you gain consistent coating quality, long-term reliability, and a cleaner production environment.
