What is PVD Coating?

       PVD stands for physical vapour deposition; one of the important new technology for thin film coating i.e., Material Science, Nano-Technology, Surface Engineering etc.

       In PVD coating technology the vapour is generated by physical mean such as Arc, Electron beam, Sputtering etc. then condenses and deposits on the wanted surface.
       Therefore there are various PVD coating systems and normally the coating is done in high vacuum equipments.  PVD can coat many kinds of Thin Film coatings with different properties to meet the varied requirement.
 
        At present many PVD systems are used in the decorative field, computer industry, electronics and as hard coating for tools and dies. 

       In Tools coating industry the PVD technology called "Cathodic Arc Plasma Deposition" is highly regarded as the best in term of economy and film quality. 

       Cathodic Arc Plasma Deposition has higher ion/neutral ratio and extremely high energetic ion when compared with other competitive systems such as Magnetron Sputtering, Electron Beam or Hollow Cathode Discharge, so it can produce stronger film with better microstructure. 

       Modern Cathodic Arc technology was developed in Soviet Union around 60's in the 20th century for millitary, aerospace and nuclear technology use. And success of this technology makes Soviet Union become the first user of Cathodic Arc Plasma Deposition for industry around 70's. 

       By the late 70's Soviet Union released this technology to the West. Since then the Cathodic Arc technology becomes widely accepted around the world and it is the very technology behind the success of major tools coater in Europe, Japan and USA.

about our coating system

     PVD system we use for coating tools and dies employ the Cathodic Arc Plasma Deposition system with our proprietary hardware improvements.

     It can coat tools below the annealing temperature of tools at 200 - 450 degree Celsius to meet the tolerance of the material/metal used. Usually high speed steel (HSS) tools are coated at about 300 - 350 degree Celsius which is below the annealing temperature of HSS so that the HSS tools will not lose its hardness.
