  • Three surface treatment processes

    Three surface treatment processes

    1)electro-galvanized
    Zinc plating is the most common coating for commercial fasteners. Moderate cost, the appearance is relatively good, include blue zinc-plated, white zinc-plated,color zinc-plated and black zinc-plated, corrosion-resistance performance is moderate

    2)Nickelage
    Mainly used for both anti-corrosion and good conductivity products.

    3)Dacromet
    There is no hydrogen embrittlement problem, and the torque and preload are consisten

  • why The internal thread of the product after the electroplating often lock teeth or lock into the phenomenon?

    why The internal thread of the product after the electroplating often lock teeth or lock into the phenomenon?

    The main reason for bad tooth pattern:

    1) the process of filament wear

    2)the pre-treatment is not clean

    3)the plating layer is too thick

    4)The teeth of the test teeth (teeth) used too long, there are wear
