Applications
● Lithium-ion battery electrode coating (cathode & anode)
● Sodium-ion battery electrode research
● Pilot-scale battery production line
● Advanced material coating development
● High-precision thin film coating processes
Working Principle
The machine operates using a slot die coating system, where slurry is delivered through a precision die head and uniformly coated onto a moving substrate.
The substrate is transported under controlled tension, ensuring stable coating conditions. The combination of controlled flow, substrate speed, and tension results in highly uniform coating thickness and excellent product consistency.
The TOB-JS350-3.0 is a high-performance slot die coating machine designed for battery electrode production and process development. With precise coating control, stable tension system, and wide material compatibility, it is an ideal solution for pilot-scale and advanced laboratory applications.
