The manufacturing of profiles and panels involves a wide variety of materials, including PVC, PP, PE, WPC, aluminum, wood, and composites, as well as combinations of these materials. Different coating processes are also utilized. Window and construction profiles are coated with films, and adhesives are used to bond the materials together. Furthermore, paints and inks are employed to achieve a high-quality, customized appearance.
In every case, the adhesion of the materials to each other is the decisive factor that determines the quality of the surface.
In profile coating, numerous factors influence the outcome, affecting the production of rejects or achieving stable manufacturing.
With regard to 360° coating, the seam area—that is, the film overlap—is subject to mechanical and thermal stress. In the event that the surface is not adequately activated in that area, there is a higher probability of seam detachment, which could result in customer complaints or the necessity for rework.
In this PlasmaTalk, we will demonstrate how Openair Plasma® activates surfaces in an inline, dry, and local manner, thereby establishing a foundation for reproducible adhesion. The primary focus of this software is the profile wrapping of window and façade profiles, as well as applications that can be transferred to many other profile geometries and materials, depending on the substrate, film, coating system, and line layout.
The following topics will be covered in detail:
- Profile coating of PVC window and façade profiles: stable activation as the basis for secure film adhesion
- 360° coating and film overlap: targeted treatment in the overlap area to reduce seam detachment
- Scaling to other profiles: which boundary conditions are decisive and how to transfer the process cleanly
- Integration into existing lines: compact, inline, without additional chemical steps
