In the automotive industry, consistent high quality processing is a requirement for efficient and cost-effective production.
The extensive and steadily growing use of adhesives, especially in the case of plastic connections, requires a consistently high level of surface adhesion so that a secure and long-term stable adhesive connection can be created.
The surface properties of polyolefins such as PP, PE with their inherently very low surface energies are the reason that subsequent adhesive processes such as gluing, painting and printing are a challenge.
Plastics such as PVC, PU, PC and others, as well as metals and glass, often need their adhesive properties to be optimized and homogenized before further processing.
Classic pretreatment processes, such as priming or flame treatment, are often associated with complex implementation and handling, high running costs for consumption and storage, high health and environmental requirements and difficult process control.
Plasma pretreatment at atmospheric pressure is a simple, inexpensive and, in particular, controllable type of pretreatment. The so-called activation enables optimal adhesive forces and wettability.
The plasma nozzles can easily be integrated into existing production lines or robot handling systems.
Due to the low plasma temperature on the surface, the pretreatment of very sensitive materials is also possible if the parameters are selected correctly. During the pretreatment, the electrical plasma process works residue-free on the surface.
Reproducible, homogeneous pretreatment, even with sensitive surfaces, through adjustable and regulated plasma discharge.
Plasma generators continuously adapt the parameters to the preset target values so that the correct treatment parameters are always used.
All process-relevant parameters are monitored by real-time monitoring with TIGRES SQI(System Quality Index) and are available for evaluation.
Through suitable processors, interfaces and protocols, the devices are fully Industry 4.0 capable.
