  • The key and important parts with tensile strength greater than 1034Mpa should be relieved of stress at 200±10℃ for more than 1 hour before plating, and the carburized or surface hardened parts should be relieved of stress at 140±10℃ for more than 5 hours. The cleaning agent used for cleaning shall have no effect on the binding force of the coating and no corrosion on the substrate. Acid activation Acid activation solution should be able to remove corrosion products and oxide film (skin) on the surface of parts without excessive corrosion on the matrix.

  • The drawing process of the product drawing process has a great influence on the product function. Generally, a large total surface reduction rate of about 90% (see area reduction rate) and a small pass surface reduction rate (about less than 23%) are selected to ensure the endurance of the product. On the high strength spring steel wire, drawing should control the exit temperature of each passage of the steel wire is lower than 150℃, to avoid the steel wire due to strain aging and appear to change the crack, which is the formation of steel wire scrap the primary disadvantage.

  • Cold galvanized, generally speaking, do not need heating, galvanized amount is little, this galvanized parts are easy to fall off in wet environment. Hot dip galvanizing, also known as hot dip galvanizing, is to melt the zinc ingot at high temperature, put some auxiliary materials in, and then dip the metal structural parts into the galvanized groove, so that the metal members are attached to a layer of zinc layer. The advantage of hot dip galvanized is that its anticorrosion ability is strong, the adhesion and hardness of galvanized layer is better.
