In the case of complex component geometries that cannot be realised in a single injection mould, the geometry must be divided and then joined together again.
Components with demanding geometries that require high strength and a high level of technical cleanliness can be joined together particularly well using hot gas welding. In this process, both components are heated with nitrogen in the joining zone, the plastic melts and the parts are joined under pressure.
In contrast to mechanical welding, this thermal welding process is particle-free. Oxidation of the material is prevented by the use of shielding gas in the welding seam area, thus ruling out thermal damage to the plastic.
Another advantage is that the hot gas welding process can be used for a wide range of technical materials. In addition, the process is also suitable for complex 3D geometries.
