Yasui Seiki precision slot die is suitable for coating thicker layers with higher viscosity coating fluids.  SLOT COATING IS USED IN THE MANUFACTURING PROCESS OF MANY DIFFERENT PRODUCTS  PRE-METERED METHOD: THICKNESS IS SET BY FLOW RATE  FLOW UNIFORMITY IN THE COATING BEAD IS STRONGLY AFFECTED BY OPERATING PARAMETERS FUNDAMENTAL ASPECTS OF SLOT COATING. . Similar to full width and stripe coating, machine direction edge quality is controlled by:. Proper cavity design for uniform fluid velocity from edge to edge. Proper die shim thickness for optimized die pressure. Shim design to minimize flow disturbances at the edges of the slot opening.
