In the past decade, slot die has become one of the most widely used coating methods in the world. While the majority of slot dies on the market require time-consuming bolt adjustments to obtain uniformity, the precision of the Yasui Seiki slot die is due to meticulous in-house machining, to the 1/1000th of a millimeter to guarantee coating accuracy. Technical Coatings International Capabilities Slot Die (Slot, Extrusion) Coating In the Slot Die process, the coating is squeezed out by gravity or under pressure through a slot and onto the substrate. If the coating is 100% solids, the process is termed ‘Extrusion’ and in this case, the line speed is frequently much faster than the speed of the extrusion. A review of the operating limits in slot die coating ... A major concern in slot die coating processes is how to determine the operating limits to set the appropriate range of operating parameters, including coating speed, flow rate, vacuum pressure, coating gap, liquid viscosity and surface tension, etc. Operating limits directly determine the effectiveness and efficiency of the process.
