Qidong Quanxin Electronics Co., Ltd. is a professional manufacturer of corona treatment machines (corona machines, electronic shock machines), with a team of experts in corona treatment equipment research. Utilizing cutting-edge electrical theories—resonant pulse width modulation technology (PWM), microcomputer control technology (Microprogrammed Control Unit), and digital signal control technology—the company produces a full range of single-phase and three-phase corona treatment machines, 3D plasma corona treatment machines, plastic cup and drum corona treatment machines, wire and cable corona treatment machines, film edge sealing machines, and static eliminators. After years of practical use by numerous customers, these products have been confirmed to be stable in performance, reliable in quality, easy to use, compact in size, lightweight, efficient, and highly reliable.
The company produces a full range of single-phase and three-phase power supply film capacitors, metal capacitors, sheets, plates, wire and cable corona treating machines, 3D series three-dimensional plasma corona treating machines, SC series cup and drum corona treating machines and film sealing machines, static eliminators, and other equipment. Mainly used for surface treatment of polyethylene, polypropylene, polyvinyl chloride, PET, nylon, fabrics, aluminum foil, and various materials' metal films. During operation, the electrodes generate corona discharge, which forcefully impacts the material surface with a large amount of plasma, penetrating into the molecular structure. This creates strong polarization of the material surface molecules, removes surface oil, and enhances the surface adhesion of the treated material, ensuring reliable printing, glue application, and lamination. Currently, corona treating equipment has become an essential pretreatment device in the production processes of printing, blowing, lamination, casting, coating, aluminum coating, fabrics, woven fabrics, sheets, plates, pipes, cups, drums, and plastic components.
