4. Ultrasonic Welding Applications:
Ultrasonic welding is found everywhere where thermoplastics are used and strict demands are placed on the method of joining. Compared with other welding methods, ultrasonic welding is particularly suitable where rapid process times, coupled with good process reliability are demanded or if no other fillers or solvents are to be used. Ultrasonic welding is also characterised by the quality, strength and accurate reproducibility of the welds.The process itself is very special. Depending on the application, the welding results depend upon various parameters. In ultrasonic welding, high-frequency mechanical oscillations cause molecular and interface friction in the joining zone. This creates the heat required for welding and the material is plasticised. Following the effect of ultrasound, homogeneous stabilisation of the joining zone is achieved as a result of brief cooling times, whilst maintaining the welding pressure. In addition, both the geometry of the sonotrodes and the anvil, as well as the shape in the welding zone itself, affect the welding result.
ultrasonic weldings cater for widely different applications in various sectors. For example, in the automotive industry, it is mainly interior or exterior components, which are welded, whilst in the packaging industry, packaging is sealed by ultrasound. In the textile industry, textiles made from thermoplastic fabrics can be joined with absolutely tight seams by fusing the materials, Other plastics industries, such as domestic appliances, electronics and electrical engineering or medical engineering, make use of the advantages of ultrasonic welding for appropriate applications.
