High frequency induction heating evaporation source is another evaporation source widely used in PVD vacuum coating equipment technology
High frequency induction heating evaporation source is another evaporation source widely used in PVD vacuum coating equipment technology. This method of heating and evaporation is characterized by high thermal efficiency, large evaporation capacity and simple equipment. Therefore, it has been industrially applied. Its main problem is that boron nitride crucibles with good thermal shock resistance and stable high-temperature chemical properties must be used. Examples of industrial high-frequency induction heating evaporators: in large-scale vacuum coating machine, for example, on steel belts In large-scale equipment for continuous vacuum aluminum plating, the high-frequency induction heating evaporation process has achieved satisfactory results.
In the past ten years, my country's vacuum coating equipment has developed rapidly due to the large demand of enterprises. Various types of vacuum coating equipment of various coating processes are constantly increasing, and their functions are becoming more and more perfect.
As far as China is concerned, the people who have paid more attention to the vacuum coating industry in the past two years are mainly concentrated in the two regions of East China and South China. The attention paid to vacuum coating in the three provinces of Guangdong, Zhejiang and Jiangsu is far ahead of other provinces. There are more than 5,000 domestic vacuum coating companies, and there are more than 2,500 in Guangdong and Zhejiang provinces, accounting for up to 50%. The two provinces play a pivotal role in leading the development of the domestic vacuum coating industry.
At present, vacuum coating machines are used in optics, glasses, plastic films, metals, lamps, ceramics, glass, cheap plastics, ceramics, as well as various plastic toys, plastic daily decorations, artificial jewelry, Christmas decorations, household appliances decoration, electrical appliances The surface of the instrument is metallized and coated, and the vacuum coating machine is widely used.
The customers we contact often have such confusion. After the demand for the coating layer of the product is large, they know what material their products need to be plated, and they also know that a layer of film should be coated on the material. However, coating machine manufacturers at home and abroad There are too many coating machines that have a significant impact on the processing of the entire product and need to be purchased. However, I don't know what vacuum coating machine to purchase, and I don't know how to purchase a vacuum coating machine suitable for my company. So, how to choose a suitable brand coating machine?
