In order to meet the market demand, our company has developed and produced a large environmental protection aluminum mirror line. Thus large float glass can be coated with high quality aluminum film by using plasma surface treatment and magnetron sputtering technology. Such films have some advantage like none of aluminum-DOT and trachoma, high definition. Its features are: 1) Maximum dimension of coating glass: 3600x2440(mm) or 2440x1830x2pieces 2)Equipped with double-end stucture, multi-chamber and multi-sputtering target configuration. All the processing including glass cleaning, coating, flow painting, drying and air cooling are accomplished in a lump. It has advantages of high efficiency, speeding, high output and laborsaving. 3)The production adopts fully automatic control to ensure industrial safety and stable quality.
