Tungsten boat is also called tungsten evaporation boat or coating boat. It is shaped by punching tungsten sheet when they are heated with designed mould. We could design different mould according to customer’s requirements or sample.
Tungsten boat has good electric conductivity, thermal conductivity, high temperature resistance and good corrosion resistance ect. It is widely used in vacuum coating industry like gold coating, sinter furnace sintering or vacuum anneal industry.
Under ideal condition, tungsten boat would be connected at both ends with electric wire, the middle of the boat body loads film material. After electric get through, the temperature goes up to around 2000℃, the film material will evaporate and cover on the surface of the workpiece.
Our tungsten boat could be alkaline washed surface or bright polished surface.

Above are standard normal tungsten boat mould. 102# & 112# is very popular in gold coating. It has higher surface requirments.
If you have special shaped requirments, inform us please, we will design the mould for you.
