    Surface coating

    In order to fulfill our dear customers’ demand , we have use below coating types to make improvement on some of our mold part product quality

    TiN (Titanium Nitride) PVD (Physical vapor deposition) Coating

    TiN is the most economical and commonly used PVD wear resistant coating and it has the following advantages.

    1. Excellent wear resistance
    2. Superb performance of lubrication
    3. Thermal stability for most cold work metal working applications
    4. High micro hardness up to 2.300 Vickers

    Note: TIN is recommended to be used with lubricants, and it is not applicable to stainless steel, nickel or copper applications

    TiCN ( Titanium Carbon Nitride ) PVD coating

    TICN can be widely applied to PVD coating on stainless steel , nickel and copper metals , and it has the following advantages:

    1. Higher hardness and lower coefficient of friction than that of TIN coating, thus, it has extremely high wear resistance
    2. Improved performance of lubrication
    3. Extremely high micro hardness up to3.000 Vickers

    Note: it’s suitable for stainless steel, nickel of copper applications

    TiAlN (Titanium Aluminum Nitride) PVD Coating

    Particularly suitable for application generating heat on surface, TiAN can covert the aluminum constituent to aluminum oxide, which provides an extra protection against shear stress and wear resistance on cutting edges. TiAN has the following features.

    1. High thermal stability
    2. Extremely high micro hardness up to 3400 Vickers.
