Our Core Advantages:
Precision Manufacturing, Exceptional Performance
CNC machining ensures uniform wall thickness, smooth inner surfaces, and precise geometry. This delivers superior thermal uniformity and thermal shock resistance, significantly reducing material sticking and extending crucible lifespan.Customized Solutions, Flexible Response
We produce non-standard sizes, shapes (cylindrical, conical, complex geometries), capacities, and interfaces. Whether you require special tilt angles, flanges, embedded threads, or specialized coatings, we can manufacture to your drawings or specifications.Material Expertise, Optimal Selection
Based on your application—such as melt type, maximum temperature, and atmosphere—we recommend and process the most suitable graphite grade, from high-purity isostatic graphite to cost-effective molded graphite.Surface Treatments, Enhanced Capability
Options include high-purity coatings (for oxidation/penetration resistance) and precision polishing (for easy release and reduced contamination) to further optimize performance for your process.
Primary Applications:
Metal Metallurgy & Refining
For melting, refining, and casting of precious metals (gold, silver, platinum), copper, aluminum, and their alloys.
Custom designs for vacuum induction furnaces, medium-frequency furnaces, and other setups.Photovoltaic & Semiconductor Crystal Growth
Graphite susceptors/guard plates for quartz crucible coatings in polysilicon and monocrystalline silicon ingot production.
Crucibles for growing compound semiconductors like sapphire and indium phosphide.New Material Synthesis & Lab Research
High-temperature sintering, powder metallurgy, synthetic diamond production, and more.
High-precision, small-volume lab-grade crucibles for R&D and pilot production.Chemical & Glass Industries
For processing corrosive chemicals or glass fiber drawing.
