Turnkey Plasma Unit for Strong Plastic/Metal Bonds

Plasmatreat

The automated manufacturing cell includes a plasma nozzle for cleaning and activating the surface, and a nozzle for applying the coating layer (© Plasmatreat)

With injection molded plastic/metal hybrid components, it is possible that in the course of time corrosive media can penetrate through the boundary layer and damage the component. Plasmatreat GmbH in Steinhagen, Germany, and their systems partner plastics producer Akro-Plastic will present a process that creates a corrosion-inhibiting plasma polymer layer on the metal insert at atmospheric pressure. After overmolding with plastic, and due to the coating, a media-resistant and durable bond is formed.

For applying the layer, a fully automatic PT1200 plasma cell is used, which can be adapted to every conventional injection molding machine. The cell contains everything required for the process: generator and a robot, control technology, a PCU plasma control unit, the plasma jet, plus all the cables and consumables. The plasma system itself consists of two separate plasma nozzles. The first, an Openair plasma nozzle, cleans and activates the surface of the robot-guided insert. Immediately after, the second plasma nozzle applies the functional coating. The process is based on the patented PlasmaPlus technology – developed by Plasmatreat several years ago together with the Fraunhofer IFAM – with which functional layers can be created with the help of a precursor added to the plasma.

The time required for pre-treating the metal is minimal; plasma cleaning and coating involve a matter of seconds. The inserts can be processed further immediately after being coated. A small conveyor belt transports them from the plasma cell to the injection molding machine. At the end of the belt, a second robot picks up the part and places it into the injection mold after being briefly warmed under an induction heater. Here, the PlasmaPlus layer creates a strong, covalent bond between the metal and the plastic.
