Intorduction
This laboratory coating machine is designed for material formulation development, coating process evaluation, and pilot-scale trials. It integrates three coating technologies - slot-die coating, micro-gravure coating, and doctor blade coating - allowing users to select the most suitable coating method according to slurry properties and target coating requirements.
Equipped with a 2 m dual-zone drying oven, the machine enables independent temperature control of each drying zone, helping users evaluate coating performance and drying behavior under different process conditions. It is suitable for laboratory coating trials involving various slurry systems and flexible substrates, providing valuable data for material development, process optimization, and future production scale-up

Solutions
Multiple Coating Technologies on One Platform
The machine integrates three coating heads, allowing users to select the most suitable coating method based on slurry rheology, target wet-film thickness, coating speed, and surface quality requirements.
By conducting comparative coating trials on the same equipment platform, users can evaluate different coating processes while reducing the need for multiple dedicated machines during material development.
Coating Trials for Different Slurry Systems
Micro-gravure coating is suitable for low-viscosity coating materials within an appropriate operating range. Doctor blade coating can be used for process evaluation with various slurry viscosities and wet-film thickness requirements. Slot-die coating is suitable for applications requiring precise slurry delivery control and accurate coating gap adjustment.
The actual coating performance depends on slurry rheology, solids content, substrate surface properties, and target coating requirements. Viscosity alone should not be used as the only factor for determining coating suitability.
Dual-Zone Drying Process Evaluation
The 2 m drying oven features two independently controlled temperature zones, allowing users to adjust each zone separately and evaluate the effects of different drying conditions on coating formation, surface quality, and residual solvent levels.
The actual drying performance depends on slurry formulation, wet-film thickness, line speed, and oven airflow and heating conditions.
