Product Description Single Side Slot Die Coating Machine For LabEquipment Functions and PrinciplesThis single side slot die coating machineis used for precision coating of cathode and anode electrode of lithium-ion batteries. It mainly consists of unwinding part, machine head part, oven part, traction part, winding part, and electric control part. Evenly coat the stirred slurry onto the substrate, ensuring that the size, weight, etc. are within the process range. After drying treatment, roll it up and prepare for the subsequent process.
