Solution to the pollution source of vacuum coating of PVD vacuum coating machine
The vacuum coating of PVD vacuum coating machine has many pollution sources, and the surface formation process is usually the first pollution. Adsorption phenomena, drying and leaching processes, chemical reactions, mechanical treatments, and diffusion and segregation processes all increase various surface contaminants. Therefore, the surface of the coating before coating must be clean, otherwise the coating will not have good adhesion. This is also true in the vacuum diffusion welding process. The strength of the welded joint is closely related to the surface cleaning treatment.
The scale of China's vacuum coating machine market ranks among the top in the world, accounting for 24.06% of the total international market sales in 2016, and Japan ranks second, accounting for 22.49% of the global market. In the same year, the market share of North America and Europe was 16.10% and 10.38% respectively. However, Chinese companies currently focus on low-end products for vacuum coating, and large-scale production lines and high-end markets are still in the hands of companies in the United States, Japan, and other countries.
Applied Materials ranks first in the global vacuum coating machine market in terms of revenue share, accounting for 23.64% of the market share in 2016. ULVAC has a market share of 14.80%, ranking second; manufacturers in Germany, the United States and Japan dominate the high-end market. Chinese manufacturers are working hard to capture market share.
In the next five years, the global consumption of vacuum coating machines will further show an upward trend. It is estimated that the market size will reach around US$4 billion in 2022. Due to fierce competition, the downward trend of industry product prices still exists, and at the same time, due to stable demand and the development of related industries. Investors are still optimistic about this industry. More new investors will enter this field in the near future.
