STT Corporation's atmospheric pressure counterless corona treatment machine
indirect discharge electrode
No worries about back leakage! A corona treatment machine that doesn't require a counter electrode, capable of processing even thick materials!
The corona treatment machine from STT has a different electrode structure compared to conventional corona treatment machines. In typical corona treatment machines, the film is sandwiched between the anode and cathode, which can unintentionally lead to issues such as back discharge. However, thanks to the special structure of the electrodes, where the anode and cathode are integrated, such back discharge does not occur, and there are no limitations on the thickness of the materials being processed. This makes it suitable not only for webs but also for molded products with height differences. (Effective plasma zone = up to 10mm) With the STT corona treatment device, even boards with a thickness of several centimeters can be processed! If you want to treat the surface of thick sheets but think plasma treatment is too expensive, please consider the STT corona treatment machine. Thanks to the special electrodes, film processing can be done without worrying about back discharge. If you are struggling with back discharge issues, please feel free to reach out. We have a demo machine available, so please do not hesitate to contact us.
Inquire About This Product
basic information
The width of the electrodes can be set arbitrarily. Normally, corona treatment is associated with thin films, but since no counter is needed, it is not limited by the thickness of the substrate. There is no concern about back discharge since the corona discharge is completed on one side. Main applications include improving the wettability and adhesion of films and sheets, and surface modification of thick resin products. *Note: This corona treatment machine cannot be used for processing metal foils or metal laminated films.*
