The common specifications of coating machines are 650, 480 and 320, of which 650 and 480 are the most common, and 320 is 12 inch, which is relatively small.
I have been engaged in the coating machine industry for many years, and I know a little about this knowledge, so I can share it with you.
650 coater can be divided into smooth coater and non-woven coater. Smooth coater can be divided into smooth coater and pattern coater. Pattern coater has 10 different coating patterns.
