Mack Rides roller coasters can be found all over the world. The company based in Waldkirch near Freiburg is a global player in the amusement industry and produces complete solutions in-house, including rails, vehicles, decorations, animations and much more. On board for the rail production: induction technology from EMAG eldec. It ensures precise heat treatment prior to final alignment of the components. A conversation with Marcel Martinetz, head of equipment design, about the special know-how of his company and the associated production solutions.
EMAG eldec is breaking new ground in the production of inductors for induction heating and relies on the latest manufacturing methods, such as additive manufacturing.
We discussed the advantages this provides and the new opportunities this opens up with Kadir Yilmazli, who is responsible for ongoing development in this area as a development engineer for additive manufacturing at EMAG eldec.
Networking @ EMO: Series of interviews with the experts at the EMAG Group with whom you can exchange views at the EMO.
“Smart technologies drive tomorrow’s production!” That is the motto for EMO 2019 in Hanover, Germany. Yet, we are convinced that not only smart technologies are important, but above all smart people—and they must be brought together to talk to one another.
That is why we will not only focus on networked technologies at the EMAG Group’s booth, but above all on networking with our visitors.
In order to let you look ahead and find out whom you absolutely should talk to at the EMO, in the coming weeks, we will regularly interview our experts who will also be attending the EMO in Hanover.
Fans are used in a number of production processes—they play a key role, for example, in extracting gases, cooling down materials or transporting solids at the heart of ventilation systems. Elektror airsystems, headquartered in Ostfildern, Germany, and with two production sites in Waghäusel (Germany) and Chorzów (Poland), is one of the international leaders in the manufacturing of industrial fans and side channel compressors. About 60,000 devices are produced here every year. For the production of its electric motors, used in a variety of fans, the Waghäusel site has been relying on UNI HEAT from EMAG eldec since May 2018: The system ensures precise induction heating of the empty stator housing before the joining process. An interview with Roland Sand, Head of the Production team at Elektror airsystems, about choosing the right supplier, the collaboration with EMAG eldec and the meaning of process reliability follows below:
Welding processes in the automotive industry pose a special challenge for production planners. The process must be performed within seconds and without any negative impact on the material – anything but a trivial requirement when one considers the high process temperatures. Pre-heating before welding, therefore, takes a key role. The component is heated precisely to the required process temperature of around 160 to 180 degrees Celsius. This prevents unwanted heating of the material structure in the heat-affected zone, the area directly surrounding the weld. Pre-heating effectively prevents the formation of cracks in the component after welding.
Induction heating is ideally suited for setting up automated production processes. The technology is easy to integrate into the overall process flow and enables the machining of very large part quantities quickly, precisely and safely. Hardening, joining, brazing and pre-heating are examples of applications that benefit from this flexible technology.
Combined with innovative drive and clamping solutions, the MIND-M plus by eldec provides its users with huge increases in productivity for induction hardening, leading to a decrease in overall unit costs. The powerful generator inside plays an extremely important role.
“Customized” is the key word when it comes to delivering a perfect production solution for building systems and machinery. Each technology is individually tailored to the customer’s environment, guaranteeing a highly efficient and optimally configured process. Induction heating in particular is one of the technologies that requires customization because the quality of the customer’s process depends on a whole range of very specific details. As the energy source, the generator plays an important role here. The experts at EMAG subsidiary eldec, based in Dornstetten, Germany, know this very well.
Experts are predicting an increased production of cars with electric motors. Though most of these cars will be hybrids, the increase in production will still pose a challenge to production planners. The question is how to process these larger quantities?
Brazing offers many benefits to every user, including: low heat input, good electric conductivity and permanently leak-tight connections. However, the method of choice is critical. For example, if ovens or gas flames are used, heat transfers into the material relatively slowly. Induction brazing, on the other hand, has many advantages over flame soldering or furnace soldering.
