Dual Doors Vacuum Metallizing Coating Machine

Vacuum evaporation is a form of physical vapor deposition used in the a process of depositing thin films of material onto surfaces. Such a technique consists of pumping a vacuum chamber to pressures of less than 10−5 torr and heating a material to produce a flux of vapor in order to deposit the material onto a surface. The material to be vaporized is typically heated until its vapor pressure is high enough to produce a flux of several Angstroms per second by using an electrically resistive heater or bombardment by a high voltage beam.
