A non-detachable fastening for sheet metals can be produced at optimum cost by using self-clinching screws under the brand names of RIVTEX® (for sheet thicknesses between 0.75 and 2.00 mm) and STRUX® (for sheet thicknesses between 2.0 and 5.00 mm). The clinching technology is suitable for steel and aluminium sheets, causes very little cost in inspection and control, and allows several clinch screws to be processed in a single stroke.

How the fastener functions The material is peeled and a collar formed so that a flush and positive fit of the fastener is created with the sheet metal material. This can either transfer very high forces (e.g. AX 20x14) or with the version that is flush with the sheet, the fastener can be used to directly mount connected parts (e.g. AX 16x4). This principle can be applied to almost every material. The benefits of the RIVORM® HR clinch nut one nut for all sheet metals up to 4.5 mm cost-saving due to fewer variants high-strength, press-hardened and hot-stamped steels very good torsional strength regardless of metal strength high pull-out force The benefits of the RIVORM® TR rivet for fitting ties and springs fully automated processing possible in the subsequent composite tool can be applied universally for different assembly jobs, such as fastening electrical control units, or other plastic parts, simply by clipping them in

By using REMFORM® screws to join synthetic materials, the cost of the inserts and the associated work step can be omitted in the injection process. The screw simply screws into an existing core hole, forming its own thread as it goes in. The asymmetric thread geometry of the REMFORM® screw ensures that the synthetic material flows towards the load flank as the thread is formed. Thus: low turning torques high vibration resistance low cracking risk high assembly reliability Additionally: The radial force offset to the radius enables a much higher tightening torque simultaneous with a smaller tube geometry. Result: much higher clamping force. Your commercial benefits: The overall cost of fastenings is reduced by up to 72%.

The future is lightweight – with Flexweld®. Flexweld®, the unique joining process, offers countless benefits, with one of the biggest advantages being the considerable weight ­reduction in the age of lightweight construction. Moreover, no additional machinery is required to incorporate it into an existing car body assembly line. significant weight saving, which provides long-term reduction in CO2 emissions joins lightweight materials to high-strength metals can be incorporated into existing assembly lines since it is possible to use the same production and welding equipment no additional qualification for workers needed complete system including full feeder and processing technology mixed production possible by adapting the spot weld gun software

TriPress® is a triangular rapid fastening system that can be clinched into plastic and light metals. During the clinching operation, the two components of the TriPress® fastener connect together quickly and economically. It is available in the following designs: Triangular shank and knurl parallel with axis provide greater torsional strength. Circumferential locking flutes on triangular shaft generate high pull-out resistance. Combination of grooves and knurls permit positive-fit fastenings and achieve high torsional torques and pull-out forces (figure 4). So the fastener can be clinched into pre-prepared holes or injected as inserts into plastic housings.

As a general rule, aluminium inserts are mainly used for joining plastics. They are used to stiffen components (tube supports) or as the counterpart to a direct fastening. With the appropriate choice of geometry and alloy they obtain outstanding fastening results. The benefits of aluminium inserts as metal-metal fastenings become evident, particularly for components that are subject to vibration stress or where operating temperatures are high. lightweight flexible durable stable environmentally friendly corrosion resistant The benefits of a trilobular cross-section approx. 35 % greater torsional torques compared with round-knurled inserts greater vibration resistance permits greater core hole tolerances when press-fitting

Every day, industries throughout the world encounter assembly problems caused by cross-threading. Cross-threading occurs when the screw is misaligned into the female thread. This creates a new thread, which destroys the female thread. Now Arnold UMFORMTECHNIK is able to supply the patented MAThread® dog-point, an innovative solution to this problem. Screws with MAThread® dog points are shorter, lighter and can be used in more applications than other special fasteners. They are easy to fit, and robust, and thus eliminate every problem that commonly occurs with regard to fitting threaded fasteners. The MAThread design allows the designer to select the point shape best-suited to feed well in the application. As the threads come into contact, the patented anti-cross thread MAThread design begins to cam over the female thread. The MAThread design now forces the two thread helixes to align every time without fail.
