Dual Coating Machine

The dual Coater processes the substrate twice through two coating units, enabling the application of two different coatings simultaneously or achieving a double-layer overlay. It is used for the production of composite coatings on materials such as paper and film to enhance functionality or improve surface properties.
Selection
When selecting, consider the compatibility of substrate width with machine width, the precision of coating thickness control, the adaptation of the drying system to the characteristics of the coating, the equipment's operating speed range meeting production requirements, and the maintenance convenience and energy consumption indicators aligning with production conditions.

Application of Two-Step Method with Pre-Coating and Fine-Coating in Eliminating Bubble Defects for Dual-Blade Coater
The dual-blade coater employs a two-step method of pre-coating and precision coating to eliminate bubble defects during the coating process. In the pre-coating stage, high shear force is applied to break the bubbles in the slurry, causing them to rupture and rise to the surface. The precision coating stage then precisely controls the coating thickness, removing any remaining bubbles to form a uniform wet film.
