Together with our partner SG-Engineering, we want to fully exploit the potential of the digital twin from the point of view of a design office and plant implementer and transfer it into practice. SG-Engineering’s practical know-how meets ASCon Systems’ software know-how. SG-Engineering knows the needs of building/plant operators and supports ASCon Systems in the design, implementation and commissioning phases of digital twin projects in real industrial plants/lines.
SG-Engineering is also working on setting up its own Digital Twin Laboratory and various practical demonstrators in order to be able to demonstrate the potential benefits of a Digital Twin Approach from practical experience for practical use. “The twin opens up so many opportunities – we must not leave them behind, but must help our customers to make a significant leap forward through the right type of digitalization”, Stefan Glanz, Managing Director at SG-Engineering.


Solution with future potential – SG-Engineering works on the digital twin

Posted by ROTOUR on Jan 8, 2019 in WIRTSCHAFT

You can have success everywhere, even in Rothenburg. It doesn’t always have to be hip hotspots like Berlin or Munich to start your own business. It all depends on vision and commitment. Stefan Glanz shows how it works. Together with his team, he is working to turn the technology of the future into reality. Digital twin is the name of the vision that drives
SG-Engineering as its new goal.

Stefan Glanz already had many years of experience in project management and in setting up a design department for production plants in the automotive industry when he dared to take the step into self-employment with his company
SG-Engineering in 2014.

Hard work at the start

As a one-man company he worked on the orders in the basement of his house. His first employee Mario Liebmann joined the company in 2016 and his second one, Peter Butzer, in 2017. SG-Engineering now has twelve employees and has been located at Ansbacher Straße 56 since April 2018. Since September, the company has even expanded to two floors, one for the twin digital laboratory and the other for the design department.

Engineers, designers, industrial mechanics and programmers form a motivated team, “because the well-being of the individual comes first,” says Glanz. Together with his wife Evi Glanz, who manages the administration, he attaches great importance to a good atmosphere, because this is the only way to work creatively and with fun. And this is reflected in his success.

Mario Liebmann and Peter Butzer are there from the very beginning.


SG-Engineering’s clients include prestigious automotive OEM’s (Original Equipment Manufacture). These are manufacturers, original equipment manufacturers or component manufacturers. Stefan Glanz and his team plan, develop and construct production plants for prototypes and bodyshells in the automotive industry, as well as special machines for medium-sized and large industrial companies.

From planning on the computer to the interaction of mechanics and electrics to the program in the stored program control of a plant, everything comes from a single source. “We always work in a team and thus make use of all our competences,” explains Glanz.

Stefan Glanz has additionally established a cooperation with the Baumann company in Rothenburg, which is responsible for the execution work. SG-Engineering also has its own assembly area at Baumann and a robot here. Here, what will shape the future of SG-Engineering is currently being developed: A model for the realization of a digital twin.

Always one step ahead

A digital twin is the virtual representation of a machine, a production cycle, a complete work or life process. Using perfect simulation, processes in the virtual world can be adapted, changed, optimized and tested in real time. The changeover to a new product requirement then takes place in reality without any time delay or production congestion and costs are saved. For industry, this means the dawn of a future with undreamed-of possibilities. “With the digital twin, one achieves an optimization that strikes through the ceiling,” says Stefan Glanz.

In 2017, Glanz came into contact with the decision makers of ASCon Systems GmbH, an innovative software company headquartered in Stuttgart with many years of experience in digital change processes in industry. They exchanged ideas, encountered the same problems, and looked for solutions. The third in the group was the Würzburg-based company Indtact GmbH, which was awarded the German Founders’ Prize. Indtact develops innovative sensor systems in the field of component and condition monitoring. Combining their strengths in the areas of software, sensors, design and planning, the three now set out to make the digital twin a reality, especially for medium-sized companies.

“We are ideally positioned for this,” says Glanz. A prototype plant is currently being built under the management of mechanical engineer Andreas Uhl. “ASCon needs hardware for the digital twin,” says Uhl. Using a manufacturing process for ballpoint pens as an example, the system will demonstrate what the digital future can achieve.

Java programmer Rui Gomes has been with SG-Engineering for almost a year. Together with ASCon he develops parts of the software for the digital twin. The system and the digital image are thus produced simultaneously and can be expanded and optimized from the outset.

Wolfgang Reu joined the team at the beginning of the year and, in close cooperation with ASCon, forms the link to the companies. This summer, the digital twin based on real industrial hardware and electronics will demonstrate its potential at the trade fair. If virtual technology becomes reality, it will revolutionize industry and life.

Converting systems to meet new product requirements costs a lot of money. With a digital twin as a counterpart to the system, not only can ongoing operation be monitored, but changeover processes can be simulated without risk and problems detected in advance. An example: Sensors can be used to measure the viscosity of oil on the basis of the flow noise. If the noise changes, you can react immediately.

All signal streams, system data, control or environmental data are recorded and processed by the digital counterpart using sensors and data from the software programs and are ready for optimization. “A digital twin therefore represents reality with all its components,” says Stefan Glanz.

Industry-independent use

However, the development of a digital twin is not only in demand in manufacturing sectors such as the automotive industry, but can also be implemented in any industry. Wolfgang Reu is thinking, among other things, of building systems, municipal management or logistics companies. The digital twin can optimize all processes, from major events where crowds have to be transported quickly to accident prevention at the workplace. The implementation into reality is then almost just a matter of form.

Stefan Glanz and his employees forge visions that could soon become reality. And not in any metropolis, but in the middle of Rothenburg.
