Slot Die Features

Slot Die is a core product that helps to apply anode and cathode active materials uniformly on the web during the coating process, an electrode process in the secondary battery manufacturing process.

Application Industries

  • Secondary battery – Cathode, anode, separator
  • Hydrogen fuel cell – MEA assembly coating
  • Semiconductor – Ceramic coating for multilayer structures
  • Building materials – Thermal conductivity and window film coating
  • Medical – Medical thin film for coating and specific thick film products
