EW Evaporation Web Coating Systems

EW Series models are deposition systems for evaporation of metal or oxides onto continuously-wound plastic film, paper or metal foil. Models range from compact types for research, to systems for mass-production. They can be used to manufacture products such as packaging materials, capacitors and magnetic tape.

Features

The substrate transfer system uses the latest winding control technology, ensuring stable transfer for every substrate material and size.

Induction heating, resistance heating, and EB heating evaporation sources are available. The optimum source for the application can be selected.

A wide range of pre- and post-process mechanisms are available to enable optimum process conditions.

Film thickness monitors for online measurement are available (transmission film thickness monitor, eddy current film thickness monitor, resistance value monitor, other)

Applications

  • Packaging materials, transparent gas barriers, gold/silver thread
  • Capacitors
  • Magnetic tape
  • Optical films
