Automatic closed-loop adjustment method
It can be understood as software-controlled micro-servo electric cylinders controlling the slurry extrusion thickness in each area through T-shaped blocks; the adjustment accuracy is 0.002mm, which not only ensures better consistency, but also realizes intelligent adjustment, improves efficiency, and saves labor
Our Core Advantage 
1,The Manual Mocrometer head adjustment is insteaded of fully automatic coating die mode controlled by a micro
cylinder. The whole process data is tracked to understand the production status in real time, and the material waste is
reduced by 8%. Intelligent production levels and competitiveness have been enhanced, coating consistency has been
significantly improved, and COV/CPK values have increased by 50%. .
2,According to the data of wet film and dry film, a dry-wet fitting model is established, and the dry film is predicted
by inference from the latest wet film data. There is no need to wait for the coating to pass through the oven! The
die head closed-loop adjustment is realized in advance, which reduces waste and the error is less than <0.2%
