Corona treatment machines come in different structural forms depending on the shape of the object being treated, but the electrical control components are largely the same. Thin film corona treatment machines are suitable for treating the surface wetting tension of films, sheets, and plates made of materials such as PP, PE, PS, PET, PA, PVC, BOPP, OPP, and PT; metal film corona treatment machines are suitable for treating the surface wetting tension of films, sheets, and plates made of materials such as aluminum foil and aluminized film; sheet corona treatment machines are suitable for treating the surface wetting tension of plastic sheets made of materials such as PS, ABS, PP, and PE; three-dimensional curved surface corona treatment machines are suitable for treating the surface wetting tension of various irregularly shaped plastic parts; and cup corona treatment machines are suitable for treating the surface wetting tension of cups, hoses, and sheets made of various plastics and paper.
The manufactured corona machine main unit uses stable, advanced, and reliable imported high-power IGBT modules and devices as the main circuit components. The main components of the control, triggering, and display circuits are composed of integrated circuits with digital display, making the equipment very safe, reliable, and durable during operation with a low failure rate. It also has advantages such as automatic protection against overvoltage, overload, overcurrent, short circuit, and shutdown, which is a popular trend in the corona industry both domestically and internationally. Due to the use of IGBT power devices, the product has a simple structure, simple circuit wiring, high reliability, high efficiency, small size, is easy to use, has one-button operation, modular structure, convenient maintenance, and low price.
