In the pharmaceutical industry, more than half of all tablets receive a film coating. A commonly used technique is drum coating, where a film solution is applied to the moving tablets by a spray nozzle. Important process parameters include the amount and temperature of drying air, as well as spray nozzle position.

The coating process is important step in the manufacture of modern pharmaceutical tablets. The coating itself can serve several function – it can strengthen the tablet, control the release of active ingredients, improve its taste, provide colour, make it easier to package and handle, and protect it from moisture.
SLOT DIE COATING TECHNOLOGY Mark David Miller, Market Development Manager, Extrusion Dies Industries, LLC, Chippewa Falls, WI Abstract Slot die coating technology is a function of the coating process, auxiliary system and fundamental technique. Slot-die processing of lithium-ion battery electrodes ... Highlights Homogenous lithium-ion battery electrodes were slot-die coated at high velocities. Coating defects were found which match but could not be explained by the low-flow limit. The film-roughness increases when the dimensionless gap width increases. A range of coating parameters was found, that defines a “quality window”. Improved Coating Window for Slot Coating | Request PDF Coating quality in the slot coating is divided into nozzle direction quality and machine direction quality. Nozzle direction quality is related to flow uniformity inside the die whereas machine ... Slot-Die Coating: Theory, Design, & Applications – Ossila
