NW-CoatML



General

ÕûÌå½éÉÜ

The NW-CoatML system is a medium-sized low-pressure plasma system capable of plasma

coating components using liquid precursors. The components to be treated are put in trays, which are inserted into the vacuum chamber.

Vacuum chamber

Õæ¿ÕÇ»ÊÒ


The process chamber is made of special grade aluminum with wall thickness of 30mm. All

welds are done in several passes at the interior and exterior of the chamber, which assures a long-lasting vacuum tightness for the full lifespan of the machine, which can easily be over 20 years.

Liquid delivery

ÒºÌåÊäËÍ

The system has standardly 1 LDM (Liquid Delivery Module) included. The LDM has all controls on board by its own internal PLC, which is connected to the main PLC of the system. It can easily be replaced by a spare LDM (plug-and-play).

The LDM allows to bring the process liquid into the right condition before supplying it as a vapor to the coating process. The LDM is connected to the process chamber by a heated and thermally insulated process line. The vapor flow gets further distributed into every process slot, by means of a proprietary heated and thermally insulated manifold.

The HMI is a 17” industrial touch screen PC and offers a very comprehensive and intuitive interface with the user. Depending on the allocated user-level, it allows to run the machine in manual or automatic mode, program process recipes or alter system settings. The HMI is also taking care of the optional historical data logging with exporting functions and standardly allows for remote access support over the internet.
