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.
