Lower Failure Rate

The stability of the equipment is directly related to production efficiency. GC20NA-C has undergone strict quality control during both design and production, ensuring its failure rate is far below industry standards.

Safety

The GC20NA-C controller features a unique shape design, ensuring perfect compatibility with explosion-proof electrical cabinets. It provides stable and safe powder supply and meets voltage control requirements in any environment.

DVC Digital Valve Technology / Precise Powder Flow Control

This technology achieves stability and high consistency in the spraying process through the precise regulation of powder output, atomizing air and delivery air.

PCC Precision Charging

Dynamic charge regulation and intelligent matching achieve efficient charging and uniform adsorption of powder particles, significantly improving coating quality and production efficiency. 

For workpieces with complex geometries (such as automotive wheel hubs and home appliance casings), its charge regulation system can dynamically enhance the electric field intensity in hidden areas like deep cavities and grooves, ensuring the powder adsorption coverage rate is further improved.

250 Programmable Spray Programs, Enabling Repeatable Coating Effects

It can be programmed individually, store 250 custom programs, and these programs can be recalled at any time, ensuring quick and convenient operation.

More efficient and convenient Coatpilot spraying system

Simpler handling of complex processes

The global modular management allows for quick deployment of process parameters among numerous types of wrokpieces,resulting in higher in higher efficiency and easier replication of quality.

Efficient and continuous coating

Activate the system's potential by incorporating automatic functions such as gap, height, and depth control. For the automation needs of highly complex workpieces, dynamic 3D coating solutions are available without programming.

Future-oriented control system

The Coatpilot system is open and can be integrated into your production environment through APls with ERP, MES , and other third-party systems. This allows for the formation of a powerful antomated prodcution systm wirh other equipment and systems.

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.
