Car Logo Aluminum Vacuum Metallizing Machine Working Theory
About Thermal Evaporation Filament Technology: Its Introducing the work pieces into the vacuum chamber, when the chamber's vacuum pressure is up to 5.0*10-2~8.0×10-3Pa with different stage of vacuum pumps ( Rotary Piston Vacuum Pump, Rotary Vane Pump, Roots Vacuum Pump,Diffusion Pump) , and then evaporate the Chrome filaments which hold in the tungsten filament ( or board). When the work pieces are turning around in a rotary driving system, the chrome material would deposit on the substrates surface and generate a highly uniform coating layer.
Car Logo Aluminum Vacuum Metallizing Machine Coating Properties
Finishing Properties: PVD chrome on PMMA (Acrylic) surface, which generates the outstanding coating layers as below: During the day time, sign symbols look like solid metal ( stainless steel effect);
while at night, they are illuminated ( LED light inside is installed ) from front, back and side views.
