PMMA Automotive Logo Billboard Chroming Machine, Car LOGOs and Signs Vacuum Coating Equipment
Aluminum Thermal Evaporation Coating System
Summary: The RTEP6638 resistance evaporation coating equipment is a cube chamber model for PVD Chrome metalizing system was customized designed and manufactured for Car LOGO board reflection film deposition.
Max. Size substrate: Diameter 5500mm, depth: <300mm.
Capacity: 2 pieces for max. Size product; 4~12 pieces depends on dimensions.
About Thermal Evaporation Filament Technology: It 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.
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.
