The aim of the proposal is the development of a new process technology for joining dissimilar and incompatible materials. Currently, there are no machines for combined hot-melt bonding and clinching in one-step (one clamping of the joining components) available. It is necessary to design and build this system technology. In the first founding period of this project, the required clinching machine with servo-hydraulic spindle drive and a torsional ultrasonic-welding machine were purchased. These were used previously to perform the respective joining processes clinching and hot-melt bonding by using torsional ultrasonic separately. With these separated technologies excellent strengths were already achieved. During the requested founding period, the single processes will now be combined in one machine. A circular horn with a concentric die is provided for the combination. In addition to the melting of the thermoplastic material (hot-melt adhesive), the horn is also used as holding-down device for the clinching process.

该提案的目的是开发一种用于连接不同和不兼容材料的新工艺技术。目前，还没有一个步骤（一次夹紧连接部件）的组合热熔粘合和铆接的机器可用。设计和构建该系统技术是必要的。在该项目的第一个创始阶段，购买了所需的伺服液压主轴驱动的铆接机和扭转超声焊接机。这些都是以前使用的执行各自的连接过程中，铆接和热熔粘接分别使用扭转超声波。通过这些分离的技术，已经实现了出色的优势。在所要求的创建期间，单个过程现在将被合并到一台机器中。为组合提供了具有同心模具的圆形喇叭。除了熔化热塑性材料（热熔胶）外，焊头还可用作铆接过程的压紧装置。
