Heavy Hex Bolt Manufacturers Introduces The Use Requirements Of Surface Treatment In the production process of non-standard bolts, it is very important to do a good job of surface treatment. In the production of non-standard bolts, what is the method of surface treatment introduced by Heavy Hex Bolt Manufacturers? 1. Mechanical plating: by coating metal particles and cold welding the coating to the surface of the product, it will affect the surface of the product. 2. Electroplating: The electroplated parts are immersed in an aqueous solution containing deposited metal compounds, and the electroplated metal is deposited by the electric current through the electroplating tank and deposited on the components. General electroplating is zinc, copper, nickel, chromium, copper-nickel alloy, etc., sometimes black (blue), phosphating, etc. 3. Hot-dip galvanizing: the carbon steel parts are immersed in a molten pool with a temperature of about 510℃. As a result, the zinc-iron alloy on the surface of the steel part gradually becomes passivated zinc on the outer surface of the product. Hot-dip aluminum plating is a similar process. Therefore, non-standard bolts need to choose an appropriate surface treatment method according to the actual situation to ensure their good performance. https://www.ydfastener.com/
