Hirano DV Die Coater

A die coater is also basically a closed coating method, and it has the advantage of coating stability, allowing for ultra-high precision coating.
There are significant variations in the wetting methods and edge shapes for a die coater, which must be determined according to the resin being applied, the substrate and the coating thickness. Depending on the fluid characteristics, it is also necessary to achieve optimal conditions including the internal shape.
To determine a die method, it is desirable in most cases to perform not only simulations but verification tests using the actual coating fluid.

Therefore, the Hirano DV Die Coater has a wide range of applications. For example, it is for thin to thick coating. Explicitly used in low viscosity thin coating. To explain, by using a vacuum box to form the film. Thus, introduced in the upper stream of the die, aiming at suppression of air entrainment and bead stabilization.
