Drop-on-demand - coating without material loss

With drop-on-demand technology, coatings can be applied almost loss-free without overspray and without material losses. This can reduce material consumption by up to 60-70 percent.

Production processes are coming under increasing pressure: material costs are rising, sustainability targets are becoming more specific and, at the same time, quality and cycle time requirements are increasing. Many coating processes continue to struggle with overspray, masking or rework. This is precisely where the solution from IPR GmbH comes in: With Accura drop-on-demand technology, components can be coated precisely and without contact - without material loss and time-consuming reworking. Instead of spreading material widely and correcting it later, it is applied directly to the right place. For production, this means less effort, more stable processes and significantly better material utilization.

With the Accura drop-on-demand application, individual drops are created at the exact moment of application. An electrical impulse ejects the medium from the jet nozzle - without component contact and without any infeed movement. Intelligent overlapping creates lines or surfaces with clear edges. For users, the advantage is evident directly in the process: they achieve defined layer thicknesses with precisely controlled droplet sizes. A single application is sufficient instead of several passes. Even complex geometries can be coated cleanly - regardless of the surface or component topography. Accura processes a wide variety of media - from aqueous solutions, adhesives and waxes to highly viscous materials. This makes it suitable for applications ranging from electronics production and battery technology to medical technology.

The benefits are particularly evident in ongoing production operations The virtually loss-free application reduces material consumption by up to 60-70 percent. At the same time, extraction systems, filter systems or complex cleaning processes are no longer required in many applications. Protective coatings on electronic assemblies, functional coatings for battery modules or precise dosing in medical applications can be implemented reliably and reproducibly.

Technology is only convincing when it works reliably under real conditions. This is why IPR GmbH offers companies the opportunity to test applications under real-life conditions before deciding on a series solution. Components, materials and processes are jointly analyzed and optimized in the IPR Technical Center. Instead of theoretical simulations, reliable results are obtained from real tests - including achievable cycle times and stable process sequences.

Helge Schneider, Head of Development at IPR, describes how closely practice and development work together: "In the IPR Technical Center, we combine problem-solving and engineering expertise with robotics know-how under real production conditions. Together with our customers, we make applications visible, reduce technical risks and create a sound basis for safer and faster decisions - from the initial idea to series production."

This gives companies clarity at an early stage as to whether a process works technically and can be implemented economically. Ottmar Kern, Head of Sales at IPR, also emphasizes the practical benefits: "For our customers, the IPR Technical Center is the place where questions become clear answers. We use real components to test whether an application works technically, what cycle times can be achieved and how reliable the process is. This provides clarity at an early stage - and a secure basis for rapid implementation in practice."

The combination of precise drop-on-demand technology and practical process development provides a clear advantage: new applications can be transferred to production safely, quickly and economically. In the end, it is not the technology alone that counts, but its benefits in everyday life: stable processes, less material consumption and less rework. If you want to further develop your application or safely test new processes, you can start your project directly in the IPR Technical Center - together with the experts who combine technology and practice (OM-3/26).
