Three Preset Spray Modes (Flat Workpieces, Re-sprayed Workpieces, Special-shaped Workpieces)

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.

Stable Performance 

Electronic components from world-class brands ensure the stability and maximum performance  of the control unit. The aluminum alloy body features excellent heat dissipation, reducing  malfunctions and extending the equipment's service life.

GCS Spray Gun Control System 

A good helper for large-scale spray gun deployment 

The GCS Spray Gun Control System is developed based on the x86 platform, featuring excellent  adaptability and scalability. It reserves digital interface APIs and supports access via the  CANBus industrial bus and external I/O signals, facilitating interconnection and  intercommunication with other production equipment (such as robots, automated powder booth  equipment, and production line PLCs) or intelligent systems (such as MES and ERP). This  enables the realization of a highly intelligent coating production process, as well as data  collection and traceability 

The system can be expanded to a maximum of 120 spray guns, capable of meeting the needs of  large-scale production, and can be freely combined according to the actual type of workpiece,  providing flexible and customized spraying solutions. 

The system can store thousands of spray formulas, ensuring quick access under different  requirements such as workpieces, colors, thicknesses, etc., reducing production changeover  time, and significantly improving production efficiency. 

By integrating the MES system, the system can automatically match the optimal coating formula  based on order requirements and workpiece specifications, flexibly adapt to various production  tasks, and achieve true flexible manufacturing. 

The built-in self-diagnosis function can monitor the device status in real time, automatically  detect and prompt for faults, ensuring that the device always operates in the best condition and  reduces the risk of downtime due to faults. 

The system supports remote monitoring functionality, allowing users to remotely view the  operating status of devices, adjust parameters, and even perform remote maintenance, greatly  enhancing the convenience and efficiency of management.

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.
