For atmospheric plasma treatment of thin, flexible materials
VITO's PlasmaZone® cleans, activates or coats thin and flexible web materials or thin plates. VITO also provides the optimal plasma process for your specific application.
Main characteristics
- The design ensures uniform treatment of large ares
- Direct plasma contact limits gas consumption and allows high speed processing
- The equipment is suited for treatment of thin and flexible web materials or thin plates
- The compact design enables easy integration in existing production lines, up to a length of several meters
- Cooled electrodes allow processing at moderate temperature
- A wide variety of chemical products can be injected directly into the plasma for permanent surface modification
- The optimised generator design ensures efficient power-to-plasma conversion
- Unique load matching enables independent power and frequency regulation
- VITO's Aplaus software allows full process automation
