Spot welding - Import export

The STS-spiral roller brush range from Kullen-Koti contains all measurements from small to extra large and this unbeatable selection of diameters makes this brush a totally reliable tool for light brushing tasks. Due to the high fill density and precisely ground surface it achieves outstanding results. A flawless radial true runing is a requirement in most cases to achieve the desired brush effect. Therefore the brush cores are electrodynamically pre-balanced and re-balanced according to the required RPM after assembly of the spiral brushes. The balancing quality refers to quality grade G 2.5 as per ISO 1940. As core material we have available: mild steel, stainless steel, non-ferrous metal or plastic coated steel. Fixing of the spiral coils The coils are generally mounted onto the roller cores with pressure rings (PRB) in order to prevent the brush from roating on the core. Depending on the work and the rotation speed of the brush the coils can also be spot-welded or screwed...

With zippers it is possible to realize simple bag packages with re-sealing option. With the Zipper Crush module, Herrmann Ultrasonic provides a suitable solution for many different types of zippers, for fixing the zipper ends at the left and right sides of the bag by means of spot welding. Tools with high-quality finishing in combination with heavy-duty generators ensure great output quantity.

The most simple way of welding thermoplastic materials is to use the ultrasonic manual welding device. This is particularly well suited for applications in prototype design, for processing of single products, small series and repairs. Regardless of caulking, swaging, staking, cutting, or spot welding, the HSG ultrasonic manual welding device is easy to use, provides variable power rating, and can be equipped with all types of conventional sonotrodes (35 kHz).

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
