Product Description

Forging / Sintering Tungsten Crucible 0.5 - 100 Litres

 

Tungsten Crucible Feature

 

1. According to different processing methods, tungsten crucibles for vacuum coating can be mainly divided into sintered molding, press molding, spinning molding, turning forming, and welding forming.
2. Turning to form is mainly applied. We recommend the working temperature of the tungsten crucible for vacuum coating should be controlled below 2600℃.
3. We can produce a tungsten crucible for vacuum coating according to the customer's drawing.
