Home plates stand up to high temperatures conveniently. They stand up to thermal shock successfully. Their permeable structure allows regulated air flow or fluid flow. This is essential for particular sintering or warm treatment procedures.

These plates are exactly formed into clean rectangular shapes. We offer numerous standard dimensions. Usual lengths are 100mm, 150mm, and 200mm. Typical widths are 100mm, 150mm, and 200mm. Thickness options generally include 5mm, 6mm, 8mm, and 10mm. Customized dimensions are readily available as well. Simply inquire about your certain requirements.

The vital function is the array of accuracy openings. These holes are machined making use of innovative CNC innovation. This makes sure stringent dimensional precision. Opening sizes correspond. We commonly machine openings from 1.0 mm to 3.0 mm diameter. Hole spacing is uniform. Regular spacing ranges from 2.0 mm to 5.0 mm center-to-center. Opening deepness is precisely controlled. It matches home plate thickness exactly. The hole pattern is usually a straight grid. This gives also circulation. The porous nature originates from the ceramic’s fundamental structure. It’s developed for controlled permeability. Porosity levels are typically between 20% and 35%. This help gas diffusion during shooting.

Material specs are essential. The alumina web content is top-quality. It is typically 95% or 99% pure Al2O3. This guarantees high solidity. Surface firmness commonly surpasses HRA 80. Home plates take care of severe heat. Optimum constant usage temperature is around 1600 ° C. They resist sudden temperature changes well. Their wear resistance is outstanding. This expands their usable life substantially. These properties make them suitable for kiln furniture. They are perfect setter plates for firing ceramics. They support electronic components during brazing. They function well in powder metallurgy processes. They are also utilized as wear linings.

Applications of CNC Precision Machining Holes Porous Wear-resistance Ceramic Rectangular Alumina Ceramic Plate Alumina Setter Plates

CNC precision machining produces permeable wear-resistant ceramic plates from alumina. These plates feature lots of accurately pierced holes. The holes are carefully sized and placed. This process makes use of sophisticated computer-controlled devices. The result is an extremely durable rectangular plate. Alumina ceramic is the base product. This product is extremely difficult. It stands up to wear exceptionally well. Alumina additionally deals with extremely high temperatures conveniently. Sudden temperature level modifications won’t crack these plates. They remain stable and strong under intense heat. This makes them perfect setter plates for kilns and heating systems.

Setter plates hold other ceramic items throughout firing. The porous openings are essential. They permit hot air and gases to flow freely around the items put on top. This ensures also heating throughout the firing cycle. Regular heating avoids bending or fracturing in the completed products. Consistent warmth distribution improves item quality considerably. Home plates themselves endure the severe heater environment every year. They resist chemical assault from lusters and fluxes. Their smooth surface area prevents sticking. Things release cleanly after shooting.

These CNC-machined alumina plates are essential in many sectors. They are necessary in manufacturing technical ceramics. Electronics components count on them. Battery manufacturing utilizes them thoroughly. Powder metallurgy processes rely on their performance. Any high-temperature procedure needing a secure, non-contaminating surface area advantages. Typical metal plates usually stop working under these conditions. Steel can warp, respond, or infect products. Alumina ceramic plates avoid these problems. Their durability reduces substitute expenses and downtime.

Custom sizes and opening patterns are readily available. Specific thicknesses can be generated. The CNC machining process permits specific modification. This fulfills precise application demands. The inherent toughness of alumina integrated with precision opening production provides unequaled integrity. Manufacturing facilities attain much better procedure control and higher yields.

5 FAQs of CNC Precision Machining Holes Porous Wear-resistance Ceramic Rectangular Alumina Ceramic Plate Alumina Setter Plates

What are these alumina ceramic plates?
They are rectangular plates made of alumina ceramic. We machine them precisely using CNC. This makes them very flat and accurate. They are porous. They have many tiny holes. This makes them resist wear well. People use them as setters in high-temperature processes.

Why use CNC machining for these plates?
CNC machining gives exact control. It makes the plates perfectly flat. This flatness is critical. It stops warping under high heat. It ensures even heat spread. The holes are machined very accurately. This precise hole pattern is vital for consistent airflow or gas passage.

How do the tiny holes help?
The tiny holes create porosity. This porous structure gives big advantages. It makes the plates lightweight. It helps gases pass through easily. This is important in furnace settings. It also improves thermal shock resistance. The plate handles sudden temperature changes better. The holes trap wear debris too. This extends the plate’s life significantly.

How hot can these plates get?
Alumina ceramic handles extreme heat very well. These plates work fine up to 1600°C (2912°F). They keep their shape and strength. They won’t melt or deform. They are stable for long periods in kilns and furnaces. This makes them reliable setters.

Are they hard to clean?
Not really. Their surface is very smooth after CNC machining. Grime and debris don’t stick easily. The hard alumina material resists scratching. You can usually wipe them clean. Sometimes a mild cleaner works. Avoid harsh chemicals. They stay looking good and functional for many uses.
