- 3. 3 RIVTAC速 Automation The technology The high-speed joining RIVTAC速 occurs in a simple and fast process. In a single step, the tack penetrates the materials and joins them efficiently without pre-punching. The tack connects with the components to be joined at high speed. The speed, which can be controlled via the adjustable pressure, is optimised to suit the materials and their thicknesses. The tack penetrates both components. A momentary rise in temperature in the joining zone and the resulting improved flowabilty, causes the parent material to be displaced into the annular grooves on the shank of the tack. As a result, there is a high form fit within the joint. Moreover, for higher-strength steel materials, there is a non-positive connection due to grouting and compression of the material. n Joining without pre-punching in case of one-sided accessibility n Reduction of joining and cycle times to a minimum n Joining of high-strength materials without distortion in the component n Flexible application for mixed joints, multiple-layer joints and hybrid joints n Optimal possibility of combining with adhesion technology n Environmentally friendly workplace design: No fumes, air extraction is not necessary n Energy saving processing Your benefits n High-strength n Suitable for visual inspection n Reproducible and process reliable n No pre-punching n Strengh and reliability Joints RIVTAC速 High-speed joining The innovative joining process for numerous materials Procedure 1.

- 4. 4 RIVTAC速 Automation The material combinations Variable material combinations become increasingly important, especially during the development of innovative automobile and car body concepts. RIVTAC速 is particularly suitable for joints of aluminium, steel, plastics, non-ferrous metals as well as for mixed joints, multiple-layer joints and hybrid joints of these materials. Example material combinations Steel sheet / Steel sheet Aluminium sheet / Aluminium profile Aluminium sheet / Aluminium profile with adhesive Joints: n Aluminium (pressure cast, extruded, sheet) n Steels n High strength steels with Rm up to 1,500 N/mm2 Plastics and fibre-reinforced plastics (e.g. fibre glass or carbon) n Also material combinations with magnesium, copper, films, metal mesh, wood, sandwich materials n Joining of mixed joints, multiple-layer joints and hybrid joints of these materials n Adhesive as a laminate layer
- 5. 5 RIVTAC速 Automation The joint qualities High-strength joints The following chart illustrates the joining strength of example material combinations under sheer and cross tension load. In addition to the pure steel and aluminium joints representing the joining technology, mixed joints are shown as well. The force-vs-displacement curves of both pure and classic mixed joints can be seen in the charts below. In spite of a lower force transmitting shank diameter of 3.00 mm, high joining strengths can be transferred by the RIVTAC速 tacks. This result signifies the further development of the mechanical joining in addition to the unique benefit of the one-sided accessibilty.
