What is ion plating (Physical vapor deposition)?

Ion plating (physical vapor deposition: PVD) is a vapor deposition method that forms a ceramic film by reacting metals such as titanium and chromium that have been plasmatized in a vacuum with nitrogen, carbon, and oxygen.
We have three types of equipment: "Electron Gun Fusion Ion Plating", "Arc Discharge Ion Plating", and "Magnetron Sputtering". can be selected, and we are good at design coloring that is resistant to scratches and abrasion peeling on metal products, and has excellent corrosion resistance and weather resistance. In addition, workpiece shapes can range from spherical to long, and we have a track record of processing even insulating materials that do not conduct electricity.

Features of our ion plating coloring

  • Stable coloring on the entire surface is possible by forming a film using a workpiece mounting jig or rotating movement.
  • A coating quality that is strong in wear resistance and has adhesion and conformability that does not peel off in bending tests.
  • A highly corrosion-resistant film that does not discolor or corrode even in CASS tests.
  • Biocompatibility is considered by using Titanium and chrome materials.
  • The load temperature on the workpiece is relatively low, 160℃ to 300°C for the gas reaction film.
  • We are good at appearance quality control, which is important for design products.

Metal plating processing as a conductive/electromagnetic wave shield on hard-to-plate materials

Metal films such as gold, silver, copper, and brass are sputtered to rotate and revolve the workpiece, and the entire surface is processed under a heat load of 100°C or less.
(Various plastics, coatings, glass, ceramics, FRP, chemical fibers, etc.)
*We cannot perform electromagnetic shielding effect confirmation tests such as EMC tests.
