Zirconia ceramic (ZrO₂) precision structural parts, mainly including ceramic plungers, ceramic shafts and special ceramic probes/capillary tubes.
These are ultra-high precision functional parts made from zirconia ceramic material through isostatic pressing and diamond precision machining. Zirconia ceramics are widely used in fields that require extremely high precision, wear resistance and biocompatibility due to their extremely high toughness (known as "ceramic steel"), hardness and corrosion resistance.
1. Detailed analysis of components
Thick cylindrical part on the left: This is the ceramic plunger. Its top is designed with a special star-shaped or spline groove for connection with a driving mechanism (such as a servo motor or pneumatic motor) to achieve precise rotation or reciprocating motion. It is often used in high-pressure plunger pumps, dispensing valves or precision metering devices to ensure the accuracy and stability of fluid delivery.
Slender rod-shaped part on the right:
Most of them are ceramic shafts/guide rails: extremely smooth surfaces, used for guidance, support or transmission in precision instruments, such as shafts for wafer transmission in semiconductor equipment.
The ultra-fine tip component on the far right: This is the ceramic probe or capillary. The tip is extremely fine and sharp and is used for contacting, spotting, injecting or detecting at the microscopic scale. For example, it is used for cell puncture in biological laboratories or for inspection of tiny solder joints in electronic packaging.
2. Core advantages
Ultra-high hardness and wear resistance: The hardness is close to that of cemented carbide, far exceeding that of stainless steel, and it is suitable for long-term high-frequency movement conditions.
Excellent toughness and impact resistance: The fracture toughness of zirconia is much higher than that of alumina, it is not easy to crack and has high reliability.
Biocompatibility: Non-toxic, non-allergenic, can be used in medical implants or in vitro diagnostic devices.
Precision machinability: Micron-level dimensional tolerances and surface roughness can be achieved to meet the stringent requirements of high-end equipment.
3. Typical application areas
Medical devices: syringe plungers, scalpel handles, dental implant abutments, blood analyzer probes.
Semiconductor and electronic manufacturing: wafer handling robot shaft, etching machine lining, precision dispensing needle.
Precision fluid control: high-pressure pump plunger, micro-dispensing valve, inkjet printer nozzle.
Laboratory analytical instruments: liquid chromatograph syringe, mass spectrometer ion source probe.
