Overview

With MEF technology, the plasma is generated by an electric barrier discharge and the beam is directed onto the surface with the aid of compressed air.

Whether a single nozzle for high-precision pretreatment, multiple nozzles for wider applications or plasma modules for extensive substrates - any application that our customer might have is possible with this technology.

Various process gases can be used to create special functional groups on the polymer surface.

Technical data MEF

Output: 200 W per nozzle
Channels: 1-2
Process gas: Air, oxygen, argon, nitrogen
Potential-free: Virtually
Transformer: internal & external
EDC technology: Integrated
NDC2 technology: Can be integrated

Scalability

The technology can be adapted to any material width. This is done by lining up together as many 140 mm wide plasma modules as needed to achieve the desired width.

Process integration

The supply lines to the MEF modules can run parallel or perpendicular to the nozzle.

Models

The following Plasma MEF models are available:

  • Single nozzle
  • Multiblock with 20 nozzles
