Our graphite crucibles are specially designed for aluminum evaporation in vacuum coating systems, offering high purity, excellent thermal conductivity, and strong resistance to thermal shock. These crucibles ensure uniform heating and stable evaporation during metallizing processes, making them ideal for applications in electronics, packaging, and decorative industries.
Key Features
High-purity graphite material (≥99.9%)
Excellent thermal conductivity and uniform heating
Low ash content (<0.1%), no contamination to aluminum
Resistant to high temperatures (up to 3000°C in inert/vacuum atmosphere)
Good anti-oxidation treatment available
Precision machining for perfect fit in evaporation systems
Aluminum evaporation for vacuum metallizing
Suitable for thermal evaporation coating in PVD systems
Widely used in:
Decorative films (e.g. PET, paper, plastic)
Packaging industry (e.g. food wrapping)
Electronics (e.g. capacitors, films)
Application
Aluminum evaporation for vacuum metallizing
Suitable for thermal evaporation coating in PVD systems
Widely used in:
Decorative films (e.g. PET, paper, plastic)
Packaging industry (e.g. food wrapping)
Electronics (e.g. capacitors, films)
We offer OEM services based on your drawing or sample, including:
Coating (SiC, Al2O3 for oxidation resistance)
Special shapes (conical, boat, rectangular)
Batch-size or high-volume supply
High Purity, No Contamination
Made from ultra-fine, high-purity graphite to ensure clean aluminum evaporation with no metallic impurities or ash residues.
Excellent Thermal Performance
With superior thermal conductivity and stability, our crucibles maintain consistent temperature distribution, reducing aluminum spattering and ensuring smooth film formation.
Strong Oxidation Resistance
Available with optional SiC or Al2O2 coatings, improving lifespan and oxidation resistance in high-temperature vacuum environments.
Dimensional Precision
Machined with tight tolerances for perfect fitting in evaporation systems, reducing downtime and material waste.
Customizable for Your Process
Shapes, sizes, coatings, and even surface finishes can be customized based on your machine type, deposition method, and film requirements.
Long Service Life
Stable performance in repeated heating and cooling cycles ensures cost efficiency and reduced replacement frequency.
