The corona machines are categorized into different structural methods based on the shape of the objects to be treated, but the electrical control parts are largely similar. The film corona treatment machine is suitable for the surface wet tension treatment of materials such as PP, PE, PS, PET, PA, PVC, BOPP, OPP, PT, etc., as well as sheets and plates; the metal foil corona treatment machine is suitable for the surface wet tension treatment of materials such as aluminum foil and aluminum-plated films, sheets, and plates; the sheet material corona treatment machine is suitable for the surface wet tension treatment of plastic sheets such as PS, ABS, PP, PE, etc.; the three-dimensional curved surface corona treatment machine is suitable for the surface wet tension treatment of various non-standard plastic parts; and the cup corona treatment machine is suitable for the surface wet tension treatment of cups, tubes, and sheets made of various materials such as plastic and paper. The main units of the corona machines currently produced use robust, advanced, and reliable imported high-power IGBT modules and devices as the main circuit components, with the main components of the control, triggering, and indicating circuits composed of integrated circuits, featuring digital indication. This makes the equipment operate safely, reliably, and durably with a low failure rate, and offers advantages such as overvoltage, overload, overcurrent, short circuit, and automatic shutdown protection. It is a popular trend in the corona industry at home and abroad. Due to the use of power devices IGBTs, the product structure is simple, the circuit connections are straightforward and reliable, with high efficiency, small size, easy operation, one-button control, modular structure, convenient protection, and low cost.

The oil-immersed high-voltage transformer features an aluminum alloy shell with die-cast monolithic molding, offering an elegant exterior, superior heat dissipation performance, durability, rust-resistant, and no leakage.

To effectively prevent incidents such as fires caused by the stoppage of corona rollers, the constant attack of corona machine sparks on the film and silicone layers, the product must be equipped with a stoppage protection feature. This not only effectively prevents such incidents but also significantly extends the lifespan of the silicone layer on the corona roller (tube), thereby effectively reducing the costs associated with routine maintenance and vulnerable parts.
