Film coating coating machine CAP series

roll-to-rolloptical

The LEYBOLD OPTICS CAP series is an innovative solution and the reference machine in the capacitor film metalizing market. The roll-to-roll vacuum metalizing system is designed with the future in mind and to meet the demanding requirements of an unlimited range of metalized films for capacitors. From standard to high-end applications, from thick to thin films, from plain to segmented designs, from thick to thin layers, from pure layers to layer stacks, every conceivable combination can be realized in one system. Flexibility is the key to success. The LEYBOLD OPTICS CAP series is available in two different sizes, 650 and 900. High productivity granted by the revolutionary SuperBias system SuperBias is a revolutionary system that consists of an electron-beam gun and two plasma cathodes. The substrate is charged by the electron-beam gun prior to the coating process, with the aim of reaching maximum adhesion of the substrate on the cooled process drum and of transferring the thermal load efficiently. After completion of the coating process, the substrate is neutralized via a plasma cathode treatment. With this technology, the maximum peak temperature of the substrates is lower in comparison to conventional systems and hence allows comparable processes to run at faster speeds. High flexibility based on flash evaporation- The development of a new free margin oil evaporator, based on a process called “flash evaporation”, is another ground-breaking innovation. This patented invention by Bühler Leybold Optics provides numerous advantages such as higher productivity, efficiency and flexibility of the system, improved quality of the products, reduced costs and operator convenience.
