Sheetfed Corona FR-33

Corona principle

Corona treatment machines are commonly known in the packaging industry as corona machines, electronic impact machines, and electric spark machines. It is academically called a dielectric barrier discharge. Mainly used for plastic film or plastic

For surface treatment of sheet metal products, when printing, laminating, film blowing, coating, gluing, material modification, polymerization, coating, casting,

Before pasting processing, in order to make the surface of the product having a stronger adhesive force (i.e. having a higher coefficient dynes), to prevent the raw materials in the production process it is now printing rejection colors,

Corruption of the compound, uneven coating leakage, etc. affect the product quality, so corona impact treatment must be performed first.

Functions and Features of Corona Machine

u The  corona machine is divided into different structural methods according to the shape of the object to be processed, but the electrical control part is generally the same.

u  Corona treatment machine for insulating materials is suitable for processingPP, CPP, BOPP, PE, PET, HDPE, LDPE, PS, PI, PS, PC, PA, PVC,ABS,

Non-woven fabric, synthetic paper and other material film, sheet, sheet surface wet tension treatment;

uThe  corona treatment machine for conductive materials is suitable for processing the surface wet tension of aluminum foil, aluminized film and other material films, plates and sheets;

u  Corona treatment machine for special-shaped materials is suitable for surface wetting tension treatment of various special-shaped plastic parts;

u  At present, the main body of the corona machine manufactured by Hefeng adopts stable, advanced and reliable imported high-power IGBT modules and devices as the main circuit components, which are controlled, triggered and displayed.

The main components of the circuit are composed of integrated block circuits and digital display, which makes the equipment very safe, reliable, durable, low failure rate, and has overvoltage , overload, and

The advantages of automatic protection such as current, short circuit and stall are the current trends in corona circles at home and abroad. Due to the use of power device IGBT, the product structure is simple,

The circuit connection is simple, reliable, high efficiency, small size, easy to use, one-button operation, modular structure, and easy maintenance.
