Preparation for Physical Vapour Deposition (PVD) Process or Electroplating

Before the PVD coating is applied, the substrate is cleaned by ultrasound in mass production facilities. The cleaning process is a multi-step process followed by rinsing steps and drying.

The ultrasonic cleaner system below was used to prepare burrs before a PVD process. Before coating, the parts need to be cleaned from oils, lubricants, cooling emulsion and particles as much as possible.

What is Physical vapour deposition (PVD)

Physical vapour deposition (PVD) are methods which can be used to produce thin films and coatings. PVD is a process in which the material goes from a condensed phase to a vapor phase and then back to a thin film condensed phase. The most common PVD processes are sputtering and evaporation. PVD is used in the manufacture of items which require thin films for mechanical, optical, chemical or electronic functions. Some examples include semiconductor devices such as thin film solar panels, aluminized PET film for food packaging and titanium nitride coated cutting tools for metalworking.
