High-end thermal spray finish products
The appeal of metal decoration lies in the variety of expressions it can produce. There are a variety of methods to create expression. Typical examples include luster by polishing, intentional lines by scraping, and discoloration like a blur due to chemical reactions. Among these, the method of creating textures on the surface is popular as a method that can create a complex expression, such as a completely new look on the metal or unevenness when light hits it. However, if the surface is simply created, it can easily peel off due to environmental factors, or it can come off with the slightest impact. In such a situation, thermal spraying technology can create not only sacrificial corrosion resistance with zinc but also design and high-grade products, and we have been refining this technology.
Type of Polished Finish
Thermal spray treatment is not our company's exclusive patent, but has long been used in the construction and shipbuilding fields to improve corrosion resistance and strength. However, because of the large capital investment required in the field of decorative treatment, it has a history of not being considered due to cost considerations. At our company, we have been trying this technology for more than 5 years now. We have been making a lot of technical trial-and-error and research, including equipment, and have been making a lot of study in the field of thermal spray treatment in the decorative field. There are a wide variety of metal surfaces that can be created by thermal spraying. The roughness and fineness alone vary from cast metal to shark skin and yuzu (citron) skin. If we add brush finishing, decoration, and polishing, the unevenness of the sprayed surface becomes a pattern as it is, and a rich expression can be obtained. In addition, combining painting and other techniques will give the surface unlimited expressive power. Furthermore, the extremely high strength of thermal spraying provides excellent durability.
Metal lineup that expands the range of design possibilities
Thermal spraying involves spraying hot metal, which may distort or melt some materials. Nevertheless, it can be used for a wide range of materials as long as the counterpart is metal. For example, copper, brass, bronze, aluminum, stainless steel, and iron. The important thing is the sealing process. In the case of stainless steel and other metals, you do not need to be that careful because the original material does not rust, but in the case of iron and other metals, you need to improve the corrosion performance. Therefore, if careful sealing treatment is not applied at the same time as the decorative treatment, the possibility of rusting or corrosion due to weathering increases. Of course, we have conducted research and development in these areas, and have now achieved a treatment that virtually eliminates these problems. The possibilities for decoration and thermal spraying are endless. However, it is also a process that is difficult to apply without the right equipment, research, practice, and improvement.
