The Technology Days 2025 focused on seven practice-oriented presentations on key topics: spacer application, glass processing, plant planning, software integration, logistics processes, automation as well as sustainability.
A central topic was the use of digital simulation technologies, which will enable virtually all Lisec machines to be mapped virtually in the future. This allows cycle times, material flows and logistical processes to be simulated realistically as early as the planning phase.

Two concepts were presented: The “perfect factory” aims for maximum automation and throughput, while the “complex factory” is designed for high flexibility with low space requirements.
IGU manufacturing: New solutions for insulating glass production were presented, such as the FSI-A frame setting station with ergonomic climbing aids and the flexible FSA-A spacer applicator. These systems enable more comfortable working and more precise setting of spacers.

Processing: In glass edge processing, innovations ranging from edge grinding to laser processing were in the spotlight. The new Litec slider technology ensures high edge quality – even with critical breakage behavior – and significantly reduces scrap. This was supplemented by new laser applications: drilling (LDP-A), decoating and structuring (LSP-A), and glass marking (LMS-A).
Robotics and sorting: Lisec also presented fully automated solutions for end-of-line processes with its new IG-Sort systems: Robotics takes over the precise placement of the glass on shipping racks – even with sensitive thermoplastic spacers. Added to this are functions such as the ejection of rejects, the handling of remakes, and temporary intermediate storage.
Sustainability as a deciding factor
In terms of sustainability, Lisec presented resource-saving technologies such as IGD-A and Litec Temperature Control, which reduce water and energy consumption. Digital tools such as the open-source tool Grafana also enable targeted consumption analysis. Lisec was awarded the EcoVadis bronze medal in 2025 for this commitment.
Another highlight was the VSL-A double bridge solution for cutting. This features self-learning capacity optimization to increase efficiency. Lisec also showcased approaches to adaptive production planning: real-time data such as error messages and order details are used to continuously calculate the optimal production plan – including fault management to ensure on-time delivery.

Factory visit at Energy Glas
The event was rounded off with a visit to Energy Glas in Wolfhagen. The glass processor manufactures highly insulating glass using Lisec technology. The tour provided exclusive insights into automated production processes.
Lothar Schleiner, Operations Manager at Gethke Glas Gronau GmbH, was particularly impressed: “I found the LSG cutting of the VSL-A very interesting, which processes glass residues of only two centimeters – that's really very little. Seeing the entire organization and automation of the production process was also very impressive for me.”
The visitors agreed that the Technology Days 2025 demonstrated how Lisec combines innovation, sustainability and digital process optimization. Lisec has once again presented itself as a driving force for the glass industry.
