Aluminum, Chromium & Nickel Mirrors Production Equipment (High Vacuum Thermal Evaporation Glass Vacuum Coating Metallization Machine)

Structure

Vacuum Chamber

It is a sturdy welded carbon steel structure and is reinforced by #18 steel profiles. Dome liked door is open outward.
Special design hinge allows easy door opening and closing.
Durable gaskets and relevant accessories guarantee perfect air seal.
There is view window allowing observation during operation. There are track rails on chamber floor.

Vacuum system consists of diffusion pump, roots pump, rotary pump and slide valve pump.
Diffusion pump core is made of stainless steel. Pump case is made of carbon steel. Two steps cooling water runs in copper tube around the case.
All vacuum valves are pneumatic controlled.
Flanges are made of carbon steel and pipes are made of stainless steel.
Vacuum meter is multiplex.

There is a transformer for evaporation. Evaporation power supply employs pneumatic electrode input structure.
Pressure regulator is oil base. Evaporation speed is adjusted by frequency converter. Evaporation ammeters are installed in three phases. Evaporation electric currents are displayed clearly during evaporation.
Pneumatic input electrode connectors are installed on top of vacuum chamber. This is to guarantee electric contact at best performance.

Substrates are put inside this rack. The substrates could be flat, curve, large or small. If necessary, proper jigs and fixtures may be required to hold substrates in positions.
Rack runs on track rails lie on chamber floor. The rack easily moves in and out vacuum chamber.
If substrates are sheets such as glass, plastic and metal panels, they are usually placed vertically in the rack.

The vacuum system is controlled by PLC. It could be run in automatic or manual mode.
All electrical and electronic parts and components are reliable and durable.
When there is no water, it alarms.
