EMG presents EMG SOLID® DFT at ESTAD 2025 in Verona – the European Steel Technology and Application Days, a leading conference for innovations in steel production and processing.
We are proud to announce that EMG will contribute to this year’s ESTAD Conference in Verona, taking place 6–9 October 2025, with a presentation on one of the most pressing challenges in electrical steel production: the precise measurement of insulating coatings. Electrical steel is a key material for motors, generators, and transformers – and its performance strongly depends on the quality and consistency of these ultra-thin insulating varnish layers.
Our presentation, titled “Advanced Coating Thickness Measurement in Electrical Steel Manufacturing with EMG SOLID® DFT”, introduces a new approach to quality assurance that sets a benchmark for the industry. It is both a technology showcase and an invitation to discuss how quality assurance can support the energy transition.

Why this topic matters
The world is rapidly electrifying. Electric vehicles, wind turbines, transformers and smart grids are driving unprecedented demand for high-quality electrical steel. Its effectiveness depends on a thin insulating coating applied to the strip. These coatings, only a few micrometres thick, provide insulation, protect against corrosion, and extend tool life.
Producers face rising demand and stricter quality expectations while established methods are reaching their limits. Beta backscattering systems, once standard, are restricted due to isotope availability. Infrared methods cannot deliver the accuracy and stability required for today’s thin coatings. The industry therefore needs reliable, real-time control of coatings in demanding production environments.
This is where EMG SOLID® DFT comes in. By applying laser-induced fluorescence technology to insulating layer measurement, EMG offers a reliable, scalable and safe solution that overcomes the weaknesses of older methods.
EMG SOLID® DFT – a future-proof solution
Our presentation will explain how EMG SOLID® DFT works, why it was developed, and what benefits it offers. The system uses ultraviolet laser pulses to excite the insulating varnish, capturing the emitted fluorescence signal. From this signal, the layer thickness is determined with great precision – even at variations as small as 0.1 µm. Because the method is optical, it is unaffected by substrate roughness and surface structure.
Key takeaways include:
- Process stability: Real-time monitoring ensures uniform coatings and fewer rejects.
- Sustainability: Less scrap and reduced use of materials support resource efficiency.
- Flexibility: The system is suitable for a wide range of insulating varnishes, from C3 to C6 classes, including self-bonding varnishes.
- Safety and ease of deployment: No radioactive sources are required, simplifying operation and certification worldwide.
Insights for industry professionals
The ESTAD audience will gain more than just an overview of a new measurement device. The presentation is designed to provide context: why coating thickness measurement matters, how the industry is evolving, and what opportunities lie ahead for those who adopt innovative solutions. Inline trials show how small variations in coating thickness can impact efficiency and downstream processing.
Attendees will see how EMG SOLID® DFT integrates seamlessly into production. Its compact design allows installation in confined spaces, and its high measuring frequency provides dense, high-quality data. The result is not only better quality assurance but also enhanced transparency across the value chain.
What visitors will take away
Visitors can expect technical insight, application experience, and strategic perspective. They will understand why coating thickness measurement is critical, how EMG SOLID® DFT provides a solution, and what advantages this brings. More importantly, they will leave with ideas for strengthening their own processes and preparing for future challenges.
