Surface treatment is a critical part of the fastener manufacturing process because it can affect the performance, durability and aesthetics of the final product. From electrogalvanizing to powder coating and hot-dip galvanizing. At Hofa, we can help you choose the right surface treatment. Below we have explained some of the options.
Sealinox is a surface treatment often applied to screws and other fasteners. The process involves applying a thin layer of a special coating to the surface of the screw, making it more resistant to corrosion and wear. The Sealinox coating consists of a combination of different materials, including chromium, nickel and molybdenum. These materials provide excellent corrosion resistance, even in aggressive environments such as salt water or acidic solutions. In addition, the coating helps to reduce friction between the screw and the material in which it is fastened, reducing the likelihood of wear and damage.
The benefits of Sealinox treatment for screws are numerous. In addition to improved corrosion and wear resistance, the coating can also extend the life of the propeller and improve performance. Screws treated with Sealinox are therefore an excellent choice for applications where durability and reliability are essential, such as in the shipbuilding, offshore and chemical industries.
Silver Ruspert is a surface treatment commonly used for screws and other fasteners. The process involves applying a thin layer of silver to the surface of the screw, followed by a coating of organic polymer layers to protect the surface from corrosion and wear. The Silver Ruspert treatment is designed to extend the life of screws and other fasteners and make them resistant to the effects of moisture, chemicals and temperature fluctuations. The coating also provides excellent adhesion and reduces the likelihood of corrosion between different metals.
This surface treatment is often used in the building and construction industry, where screws are exposed to the elements and other challenging conditions. The use of Silver Ruspert-treated screws can contribute to the overall durability and safety of construction projects and other applications. In short, Silver Ruspert treatment provides excellent protection against corrosion and wear and prolongs the life of screws and other fasteners.
