Product Name:
Zirconia Ceramic Filling Pump Fluid Control Structural Components
Product Material:
Yttria-Stabilized Tetragonal Zirconia Ceramic (Y-TZP). For areas requiring extreme wear/corrosion resistance or higher thermal conductivity, Zirconia-Silicon Carbide (ZrO₂-SiC) or Zirconia-Aluminum Nitride (ZrO₂-AlN) composite ceramics can be utilized.
Material Characteristics:
Exceptional fracture toughness (impact resistant, K₁c: 8-12 MPa·m¹ᐟ²), Ultra-high hardness (HV >1200) and extremely low wear rate, Superior chemical corrosion resistance (tolerant to strong acids, alkalis, organic solvents, and Li-ion battery electrolytes), Extremely low metal ion leaching and zero magnetic properties, Good biocompatibility and food safety, Moderate coefficient of thermal expansion (~10×10⁻⁶/K) compatible with various metals, Capable of achieving nano-level ultra-smooth surfaces (Ra < 0.02 µm) to reduce flow resistance and adhesion, High mechanical and flexural strength (>1000 MPa).
Application Fields:
Pump bodies, chambers, pistons/plungers, valve seats, valve cores, diaphragms, and fluid manifold plates for high-precision filling pumps; Quantitative filling and transfer of lithium battery electrolytes and electrode slurries; Sterile filling of high-value pharmaceuticals and protein preparations in biopharmaceuticals; Precise dispensing of high-purity chemicals in the semiconductor industry; Micro-dosing filling of high-end cosmetics and fragrances.
Application Industries:
New Energy (Lithium battery manufacturing equipment), Biomedical (Pharmaceuticals, high-end medical devices), Fluid Control (Precision metering and filling), Semiconductor Manufacturing, Advanced Mechanical Equipment.
Processing Difficulties:
Machining pump bodies and manifolds with complex 3D internal flow channels, high aspect ratio holes, and irregular curved surfaces; Ensuring ultra-high straightness and roundness of pistons/plungers and achieving micron-level dynamic clearance with pump chambers; Achieving nano-level flatness and super-mirror finish on large-area sealing planes (e.g., valve seats); Controlling deformation and stress concentration in thin-walled, multi-cavity structures during sintering and machining; Guaranteeing all flow channels and contact surfaces are free from machining defects to prevent media retention or contamination.
Processing Flow:
Formulation of high-purity nano-zirconia powder and slurry homogenization → Precision Ceramic Injection Molding (CIM) of complex structural green bodies → Catalytic debinding and staged presintering → High-temperature atmosphere-controlled sintering (HIP optional) for densification → Rough machining and datum establishment using high-rigidity CNC machines → Ultra-precision slow wire cutting/grinding of core flow channels and mating surfaces → Ultrasonic-assisted precision drilling and polishing → Multi-step Chemical Mechanical Polishing (CMP) to achieve ultra-smooth functional surfaces → Full dimensional inspection via Coordinate Measuring Machine (CMM) → Surface cleanliness and ion leaching analysis → Performance simulation testing (flow, pressure) → Vacuum packaging in a class 1000 cleanroom
Delivery Period:
Standard piston/valve seat components: 55-85 days
Complex integrated pump bodies, manifolds, or multi-component成套 solutions: 90-150 days
