ARNOLD UMFORMTECHNIK GMBH & CO. KG

Lightweight structures in the automobile industry demand savings in materials and weight, while using materials and components with high load capacities. Plastic-moulded bushes take account of this development. They reinforce the plastic, make weak points for load-bearing functional elements and receive the pre-load forces of screw fastenings. The use of aluminium bushes saves even more weight, providing sophisticated solutions when combined with TAPTITE 2000® thread-rolling screws. Conform® bushes indicate high accuracy in length and diameter.

Toothing is a frequent design element. They are complex in geometry, and their manufacture requires heavy machine use. Previously, toothed parts were mainly manufactured in a cutting process with a finishing process that followed the heat treatment stage. But we produce toothed parts in a cold-form process, thus providing the following benefits: customer-specific external geometries greater endurance strength greater mechanical load resistance press-smooth surfaces high accuracy of shape and position saving on materials

The requirements of modern screwdriving systems are becoming increasingly complex. Besides achieving the best possible seat for the tool, the most important criteria for driving tools are service life and torsional stability. The TORX PLUS® provides enormous advantages. TORX PLUS® provides these advantages, due to the following design characteristics: The actual working angle is 0° Larger cross-section on cam faces Lower chamfering on application of force Where TORX PLUS® drivers are used the head height can be minimised, thus reducing the overall weight of the component. This is made possible with the improved force application process, which ensures decreased penetration depth.

Time and again, our systematic research and development work results in multi-functional fasteners that, because of their shape, are able to combine two or more functions. Some examples of multi-functional combinations: joining and sealing and decoupling joining and bearing and drive with articulated joint receptacle with shear-off element

The trend – particularly in the automotive industry – is towards lightweight materials. Aluminium and magnesium alloys are in increasing use in many fields of technology. So fastening technology needs to adapt too. Aluminium offers countless options because the material is so versatile for cold forming. Under the Alufast® name ARNOLD UMFORMTECHNIK has brought together screw fasteners and form parts made from aluminium. Our many years of experience working with aluminium, including extensive research are your guarantee of optimum fastening results. We are constantly optimising our processes, ensuring that our Alufast® products are always at the latest state of technology.

Using TAPTITE 2000® ensures that in metal-joining applications, you can eliminate work processes such as tapping and the use of additional fastening elements. The fastener is screwed straight into a cast or drilled core hole. The polygonal cross-section geometry of the shaft of the screw ensures that the thread is chiplessly formed, so that if a repair is needed it can accept a conventional threaded screw. This provides some significant quality advantages: easy to position the screw low tapping torque high vibration resistance high vibration resistance high pre-load forces high assembly reliability Your commercial benefits: The overall cost of fastenings is reduced by up to 88%.

Using Sheetite® ensures that in metal-joining applications, you can eliminate work processes such as thread tapping, and also dispense with additional fastening elements. The fastener is screwed directly into a metal rim-hole or a pre-drilled metal sheet, using existing plant and equipment. The polygon-shaped cross-section geometry in the thread-tapping section of screw's shaft ensures that the thread is chiplessly formed, so that if a repair is needed it can accept a conventional threaded screw. reliable low cost flexible easy to assemble very stable reduces number of variants

Manufacture by machining is battling against the rising cost of materials and long machining times. That's why many companies are finding our forming process for hollow parts of increasing interest. We have other forming options for machine-finishing in-house. Our cold-forming process is distinctive – including for thin-walled hollow parts because of: rolled (chip-free manufacture) external threads suitable surfaces for maximum corrosion requirements Some examples of Conform® hollow parts and nuts: sensor housing union nuts for hydraulic, brake and fuel lines clinch nuts

The Flowform® screw is a polygonal screw based on TAPTITE 2000®, which makes use of the technology known as "flowhole-forming" in manufacturing processes. Using this technology the Flowform® screw causes the sheet metal to heat, using a combination of axial force and relatively high screwdriver speed . Once the material has been penetrated the polygonal shape of the screw forms a calibrated metric female thread which can accept a metric screw in the event that a repair is required. After the torque-controlled assembly process the formed through-hole adjusts optimally to the contours of the screw. This gives the following advantages: Higher process reliability in the screw fastening with the option of a larger screwdriver shut-off window More flexibility when selecting the screwdriver, and more straightforward monitoring of the assembly process. In addition the Flowform® screw considerably reduces screw-in times.

Considerable reductions in time and money can be made by using LocTec® lock fasteners to create lock fastenings. The screw is simply screwed in using the special locking bit - job done. There's no need for any further locking measure - such as driving in steel balls, or using breakaway elements. The special flank geometry on the screw drive allows the screw only to penetrate inwards. Any attempt to drive it out, even using the locking bit that was used to fit it, will result in the fitting tool being automatically driven out. It means that the fastening can be undone only by mechanically adapting the screw head.
