SLOT-DIE-COATERS BY FOM TECHNOLOGIES

Slot-Die Coaters

Slot-Die Coating

M. Braun Inertgas-Systeme GmbH acts now as the exclusive distributor of FOM Technologies in:

- Germany, Austria, Switzerland and France
- USA, Canada and Brazil
- South Korea.

Slot-die coating is a highly scalable technique for rapidly depositing thin and uniform films with minimal material waste and low operational cost. Slot-die coating technology is used to deposit a variety of liquid chemistries onto substrates of various materials such as glass, metal, and polymers. This is achieved by precisely metering the process fluid; dispensing it at a controlled rate while the coating die is moved relative to the substrate.

Slot-die-Coaters Integration

Optimum system integration has always been one of MBRAUN's strengths. From small laboratory instruments to complex process equipment - MBRAUN will find the right solution for you to integrate your process tool into an inert gas system. Focusing on process stability, optimal ergonomic operation of the equipment and costs in terms of integration and operation, there is a wide range of solutions. Our team of specialists is ready to help you find the right solution for your application.

FOM products can be purchased not only as a stand alone part. Together with the specialists from FOM Technologies, the integration into a glovebox and the operation under inert gas (nitrogen or argon) were already taken into account during the development of the new Slot Die Coater systems. The slot die coaters from FOM Technologies are designed in such a way that subsequent integration into a glovebox is also possible. Whether in a simple inert gas enclosure or with laminar flow to effectively prevent particle contamination, the systems from FOM Technologies and MBRAUN are optimally matched to each other.

The coater is based on a digitally controlled platform and provides process control and complete process data logging with export functions to enable researchers to analyze this data.

Data management

Automated documentation is key to handle large data volumes. The complete coating conditions are automatically logged by the control software and can also be printed alongside the coated area by a synchronized barcode printer/reader.

Coating & printing methods

The FOM moduloR2C facilitates the integration of multiple coating and printing methods into the machine frame, for example, slot-die coating and flexographic, inkjet, or rotary screen printing. In principle, any deposition method can be integrated. Designed to handle a wide range of substrates it is currently running with carbon fiber tows, multiple plastics, paper, metal foils, and flexible glass.
