Precision customization: drilled and deep-drawn crucibles with custom sizes, tapers, and wall thicknesses; small-batch sampling available.
High-temperature stability: reliable to 1800 °C (continuous) and 2400 °C (peak) for demanding melt and sinter processes.
Corrosion/oxidation resistance: stable performance in reactive environments; suitable for acids/alkalis (except HF).
Process control & QA: dimensional/visual/chemical/NDT inspections ensure consistency for capacitor, metallurgy, and evaporation duty.
Rare-earth metallurgy: high-temperature melting containers resisting metal erosion and reactions.
Electronic capacitors: anode load plates and sintering crucibles for precise, stable production.
Chemical processing: corrosion-resistant vessels for acidic/alkaline media (except HF).
Evaporation systems: evaporation crucibles and liners for thin-film coating.
Dimensional inspection
Visual & surface appearance check
Chemical analysis
NDT: liquid penetrant, eddy current, ultrasonic testing
