Problems solved by technology

In order to better meet this process, the vertical magnetron coating machine adopts glass heating and infrared heating, which is simple in design and meets the needs of the process, but there are some problems in itself, which lead to low quality of anti-reflective conductive film coating and low production capacity.

Many companies use horizontal continuous magnetron coating machines to better overcome the above problems, but there is a bottleneck in uniform heating on the panel before the anti-reflective conductive film
