Complete turnkey solution for coating with the Plasma-SealTight® process

The turnkey, fully automated PTU1212 plasma cell was developed by Plasmatreat to enable the shop floor implementation of Plasma-SealTight® technology. The cell, which can be adapted to suit any conventional injection molding machine, enables the very rapid and environmentally friendly inline pretreatment of mass-produced plastic-metal components.

The PTU1212 contains everything the pretreatment process needs, from generator, robot, control technology, PCU plasma control unit and plasma jets to cables and consumables.

Plasma process engineering in the automated manufacturing of hybrid components

Two plasma systems placed side by side perform the plasma treatment. In the first step the robot – or in the case of smaller versions, an XY axis system – passes the metal inlay beneath an Openair-Plasma® nozzle. Here the surface of the inlay is cleaned to molecular level to remove all contamination and create the conditions for optimum wettability. Immediately after cleaning, the second plasma system applies the functional coating to the metal inlay using the Plasma-SealTight® process.
