Roller Ink Coater

The roller-type ink Coater uniformly transfers ink onto the substrate surface through the rotation of rollers, achieving quantitative coating. It is used for surface treatment of materials such as paper and film, allowing for the adjustment of coating thickness and uniformity.
Selection
Select the roller material and hardness based on the substrate type, determine the roller gap and pressure according to the coating thickness requirements, match the roller speed with the production speed, and adjust the doctor blade angle considering the ink viscosity.

How to choose a laboratory coater? Which one should you buy: wire bar, scraper, or slot die?
This article introduces three methods for selecting laboratory coating machines: wire bar coating is suitable for low-viscosity coatings, offering low cost and simple operation; blade coating is ideal for medium-to-high viscosity slurries or those containing particles, with a wide range of film thickness control; slot-die coating provides the highest precision and is suitable for high-end applications such as electronic films.
Comparison of Coating Accuracy between Laboratory Blade Coater and Slot Die Coater
