8 Production process:

raw Materials (tungsten powder) --- isostatic pressing --- mechanical processing - --IF induction sintering --- mechanical processing-detection check--- tungsten cruciblesSpecial sizes can be manufactured based on customers' requirements.





9 Production equipments: CNC vertical turning machine, CNC milling machine, wire cutting machine



10 Application:

Since the melting point of tungsten has reached 3410ºC, tungsten crucible is widely applied in industry

furnace such as sapphire growth furnace, quartz glass melting furnace, and rare earth smelting furnace.

The temperature in working environment of tungsten crucible is above 2000ºC.

For sapphire crystal growth furnace, high-purity, high- density, no internal-crack tungsten crucible with

Other features of exact measurement and smooth surface has decisive influence on success ratio of

seed growth, quality control of pulling crystal, metamictization pot-committed and service life during

sapphire growth process, and we are willing to be checked by professional units.
