Design Issues for Slot-Die Coating Heads - Case Study

ABSTRACT

In this article, the authors briefly present the development, features, operating principles, and typical applications of slot-die technology. Slot-die technology is a coating method in which a consistent thickness, coating layer, can be applied to a receiving surface in an almost completely closed system. The technology was first used in the production of films but is now used for the application of a wide variety of coatings (e.g., plastics), from battery production, through semiconductor production, to solar cell production. It can also be used to make membrane air filters / filters, which can help to overcome today’s covid epidemic. Due to the proliferation of electric cars, the production of batteries has become an increasing slice of industrial production. In this article we present in detail, in a systematic way, the information gathered during the literature search, which we used in our work. In this article we present with a case study, the problems and experiences that arose during the design and manufacture of a coating machine operating under laboratory conditions. The construction of the machine was done with the technical assistance of a joint project with an industrial partner. The laboratory machine will be suitable for sheet-to-sheet coating. The article presents strength and deformation simulations along with the experience gained during the production of the coating machine.
