Aluminum oxide ceramic perforated plate

Customer pain point: Why is my precision filtration project always stuck in the “punching” stage?
We need a material that can withstand high temperatures, corrosion, and achieve micrometer level precision filtration. Why do ordinary metal filters always fail quickly
Can the aperture of ceramic perforated plates really be below 0.1mm? Will long-term use cause blockage or breakage? ”
Are manufacturers willing to accept orders for small batch customized alumina ceramic perforated sheets? How long does the delivery time take
If you are looking for a ceramic punching element with high hardness, wear resistance, and strong hole consistency for vacuum suction cups, precision filtration, flow control, or semiconductor equipment – then alumina ceramic punching plates are designed to solve these problems.

Not only ‘punching’, but also a manifestation of precision engineering

1. Ultra high hardness and wear resistance
   Aluminum oxide (Al ₂ O ∝) ceramics have a hardness of HRA 85 or higher, second only to diamond. Even under long-term erosion by high-speed airflow and particulate media, the edge of the hole will not collapse and there will be no scratches on the surface.
2. Micron level aperture accuracy
   Using laser or precision mechanical drilling, the aperture tolerance can be controlled within ± 0.01mm. The minimum aperture can reach 0.05mm, with uniform spacing between holes, effectively preventing “cross flow” or “filtering blind spots”.
3. Corrosion resistance and high temperature resistance
   Not afraid of strong acids and alkalis, it can work stably for a long time in a high temperature environment of 300 ℃. Specially suitable for harsh working conditions such as chemical filtration, photovoltaic wet process, plasma cleaning equipment, etc.
4. Customization capability fully covers
   -Dimensions: Outer diameter 5mm~300mm, thickness 0.2mm~20mm
   -Hole type: circular hole, square hole, waist hole, honeycomb array
   -Layout: concentric circles, matrix, customized customer drawings
   -Edge treatment: chamfering, no burrs, flat polishing

What specific problems can it solve for you?
Metal filter NetEase corrosion and deformation: Ceramic chemical inertness, permanent no deformation
Large aperture deviation and unstable filtering accuracy: laser drilling+full inspection to ensure consistent size of each hole
Sealing failure at high temperatures: Ceramic has a low coefficient of thermal expansion and is stable when combined with metal seals
High cost for small batch customization: The flexible production line supports 1 piece for sampling, and 100 pieces for batch production using the same process
Frequent shutdown and cleaning of equipment: Smooth surface+self-cleaning hole design, extending maintenance cycle

Typical application scenarios (anonymous customer cases)
Case A: Demagnetization filtration of new energy lithium battery materials
Customer background: A manufacturer of positive electrode materials, whose original stainless steel filters are worn through every 2 weeks in the slurry, and the leaching of metal ions affects the purity.
Solution: Use 99% alumina ceramic perforated plates with a diameter of 0.2mm and an opening rate of 42%.
Effect: The service life is extended to over 8 months, with zero introduction of metal foreign objects, saving approximately 230000 yuan in replacement costs annually.
Case B: Vacuum suction cup for semiconductor wet etching equipment
Customer background: Equipment manufacturers need a suction cup sheet that does not generate static electricity and has extremely uniform pore distribution.
Solution: Customize aluminum oxide plates with a diameter of 152.4mm (6 inches), a hole diameter of 0.3mm, and a hole spacing of 1.2mm.
Effect: The wafer is adsorbed smoothly without any marks, and the vacuum response time is reduced by 0.3 seconds. It has now entered its global procurement list.
Case C: Food grade spray drying tower nozzle protective cover
Customer background: In the high-temperature steam environment of dairy enterprises, metal mesh covers are blocked and scrapped every month.
Solution: Aluminum oxide perforated plate, thickness 1.5mm, aperture 0.8mm.
Effect: It can run continuously for 9 months without replacement and can be cleaned in situ with a high-pressure water gun.

Whether you need sample production or bulk supply, whether the aperture is 0.05mm or 5mm, and whether the plate diameter is 5mm or 200mm.
