Core Value and Machining Advantages
Precision Machining, Stable Performance
High-precision CNC machining ensures strict control over the boat’s carrying surfaces, positioning structures, and overall dimensions. This guarantees stability during workpiece placement, uniform thermal distribution, and batch-to-batch consistency, effectively improving product yield.Excellent Thermal and Chemical Properties
High-purity graphite materials are selected for their superior thermal conductivity, thermal shock resistance, and high-temperature strength. They maintain structural stability in oxidizing, reducing, or inert atmospheres and offer good corrosion resistance to most acids and bases, withstanding severe thermal cycling.Customized Design, Process Compatibility
We provide comprehensive customization tailored to your specific process requirements:Structural Optimization: Designs with appropriate wall thickness, reinforcing ribs, and airflow channels to balance strength and thermal efficiency.
Functional Integration: Machined positioning slots, workpiece separators, temperature measurement holes, lifting holes, etc., for immediate use.
Specialized Designs: Dedicated boat designs tailored for industries such as photovoltaic silicon wafers, lithium battery materials, and sapphire.
Scientific Material Matching
High-Purity Isostatic Graphite Boats: High purity (>99.99%), excellent isotropy, and superior thermal shock resistance—ideal for semiconductor, photovoltaic, and other high-end applications.
