[0002] Vacuum winding coating equipment is an effective means to realize the metallization and functionalization of flexible substrate surface, which has the advantages of wide plating raw materials, high uniformity of coating, easy plating of multi-layer composite film system and high precision of film thickness. In recent years, with the progress of technology, vacuum winding coating equipment has been developing towards large-scale and multi-chamber.
