  • Surface treatment method of screw fastener

    Screw fasteners are the most widely used mechanical basic parts and are in great demand. Surface treatment is the process of forming a covering layer on the surface of the workpiece through a certain method. Its purpose is to give the product surface a beautiful and anti-corrosion effect. The surface treatment methods carried out are attributed to the following methods:

  • What are the requirements for screw fastener plating?

    Electroplating is a common method of surface treatment for hardware screws and other fastener products. Under normal circumstances, the quality of electroplating is mainly measured by its corrosion resistance, followed by appearance. Corrosion resistance is to imitate the working environment of the product, set it as the test condition, and conduct a corrosion test on it. The quality of electroplating products is controlled from the following aspects:

  • Development and Application of Online Thickness Measurement System for Galvanized Sheet

    Galvanized steel sheet is to prevent corrosion on the surface of the steel sheet and prolong its service life. The surface of the steel sheet is coated with a layer of metal zinc. This kind of galvanized steel sheet is called galvanized sheet. Galvanizing is an economical and effective anti-rust method that is often used. About half of the world's zinc production is used in this process.
