This time Balzers said it would do it. After returning to Mr. Angehrn, he returned to Suzhou very quickly and found another factory. I certainly tried my best. The empty factory was found, and the first general manager was also set. I remember that it opened to the public in early 2004.
During that period, Belekert, a Belgian company specializing in DLC coating, also settled in the Suzhou Industrial Park. It was only two kilometers away from Arnold and came to Singapore's Sebel coating. In 2005, it was in Arnold. Under the office building, IonBond, the world's second largest coating service company from Switzerland, arrived in Star Arc coating company StarArc in 2006...
In just three years, Suzhou Industrial Park suddenly became the hot land of coating, China's coating center!
In addition, in the past few years, the establishment of coating service centers in China is also the British Teer in Kunshan, Switzerland's Pla-tit in Shanghai, Germany's Sulzer in Shanghai, Japan's Sunstar in Wuxi, Shenyang, Germany. PVT is in Harbin.
Hula la for a while, the international mainstream coating companies have basically settled in China!
III Brief History <br> <br> tool coating means coating thickness of coated film is soft stage or the hard film on the surface layer of the tool microns, to improve wear resistance of the tool, the purpose of reducing the friction coefficient.
The hard coat coating technology originated in the 1950s and 1960s. It is an early practice to use the CVD method to perform TiN coating on cemented carbide indexable inserts to improve cutting performance. However, the coating temperature of CVD technology is too high to be used for the coating of high speed steel tools. The coating temperature of the PVD method can be set at 80 ° C - 480 ° C, so the coating problem of the high speed steel tool is well solved, but it is the 1980s that really began to be popularized in the market. At the exhibition in Stuttgart, Germany in 1980, the German company G exhibited the first gold-coated high-speed steel drill bit coated with TiN, which caused a great sensation in the cutting tool industry. However, it was generally believed that the cost of coating was too high to be promoted.
The fact is that TiN coatings for tools (bits, milling cutters, etc.) have been rapidly promoted in industrial countries such as Europe and the United States in the 1980s. The appearance of TiAlN and its composite coatings in the 1990s was also rapidly promoted.
Up to now, there have been many types of coatings, and their performance has been greatly improved. TiN, TiAlN, TiCN, TiC, CrN, etc. are the most common coating varieties. DLC has been promoted. Recently, the hardness of ta-C coatings introduced by coated rookie star arc coating company has been as high as HV7000!
The manufacturers of coating furnaces in the world used to be vacuum furnaces because the vacuum in the coating furnace was to be pumped up to 0.01 Pa to prevent the oxygen in the air from affecting the coating quality. At present, the best coating furnaces are still in Germany and Switzerland. There are also several companies that only provide furnaces, but the core technologies such as control software are developed by the manufacturers themselves. So don't be surprised when you see the coating furnaces of different coating equipment manufacturers look exactly the same and can get along with each other!
