Corona discharge rack

Category：

The product adopts a split structure. The control system and the high-pressure oil tank are separated, so the high-pressure oil tank can be installed near the discharge rack, which can greatly shorten the transmission distance of the high-voltage lines and greatly avoid the impact of excessively long high-voltage lines on the safety of personnel and machines.

Corona Treater Features Summary

I. The product adopts a split structure. The control system and the high-voltage oil tank are separated, so the high-voltage oil tank can be installed near the discharge rack, which can greatly shorten the transmission distance of the high-voltage line and greatly avoid the impact of excessively long high-voltage lines on the safety of personnel and machines.
II. Integrated drive control design. It can be installed in the cabinet, which is more convenient and beautiful.
III. The human-machine interface provides digital tube display and touch screen display, which can be used alone or in combination.
IV. The bit control and registers of RS485 can be opened to customers, and customers can design their own host computers (touch screen or PLC) according to their needs, making it easier for customers to use.
V. Rich external ports provide convenient solutions for more functions.
1. For speed sensors, low-cost Hall sensors and high-precision encoder interfaces are available.
2. There are independent external start and emergency stop ports.
3. Small signal OC alarm output and relay alarm output.
4. With material shortage and blockage detection.
5. With automatic power adjustment. Automatically adjust the power output according to the material output speed, without manual adjustment.
6. High-power corona treater with ground current detection. Even if the corona treater works in a very humid environment, the corona treater can still work normally and adaptively, and will not damage the corona control system.
7. Sensitive high-voltage open circuit, short circuit, and overcurrent detection make the equipment run more safely.
8. Automatic adjustment of output power PID makes the output more stable and reduces the impact of power grid voltage fluctuations. Greatly improves product consistency

Accessories

The Corona discharge rack is a specialized component designed to generate high-energy plasma for surface treatment applications, ensuring optimal adhesion and coating performance on non-conductive materials. By utilizing a controlled corona discharge process, the Corona discharge rack effectively increases the surface energy of substrates such as plastic films, foils, and sheets. This process enables better bonding of inks, adhesives, and laminations, which is essential in industries such as printing, packaging, and extrusion. The Corona discharge rack provides a uniform and efficient treatment, enhancing the surface characteristics of materials that typically resist wetting and adhesion.

Built with precision and durability in mind, the Corona discharge rack features high-quality electrodes and insulated dielectric components that ensure consistent and stable corona output. The design allows for even energy distribution across the treatment area, eliminating the risk of over- or under-treatment. Its modular and compact structure makes integration into existing production systems simple and efficient, whether for narrow or wide web applications. With advanced power control and feedback systems, operators can easily adjust voltage, frequency, and discharge intensity to match different material types and line speeds, guaranteeing reliable and repeatable treatment results.

Engineered for industrial-grade performance, the Corona discharge rack is constructed with corrosion-resistant materials and efficient cooling systems to ensure long-term stability in demanding operating environments. It includes built-in safety features such as overcurrent protection and automatic shutdown for fault conditions, minimizing operational risks and maintenance downtime. By improving ink adhesion, print clarity, and coating durability, this system contributes to enhanced product quality and production efficiency. Whether applied in film conversion, flexible packaging, or electronic component manufacturing, the Corona discharge rack delivers exceptional surface activation performance, making it an indispensable tool for modern material processing and finishing lines.
