Specifications of Whole 10PPI 20PPI 30PPI Alumina Zirconia Sic Foam Ceramic Filter for Metal Casting

Below are the requirements for our alumina zirconia silicon carbide foam ceramic filters for metal casting. These filters come in 3 pore thickness: 10PPI, 20PPI, 30PPI. PPI suggests pores per inch. Higher PPI numbers mean better pores.

The major products are alumina, zirconia, silicon carbide. This mix produces a very solid filter. The product manages severe heat well. It resists thermal shock when hot metal flows with. The filters are chemically steady. They do not react with many molten metals.

Filter sizes are standard. Common sizes include rectangles like 180x180mm, 230x230mm. Density is normally around 50mm. Custom-made sizes and shapes are feasible. Simply ask.

The various PPIs offer specific purposes. Use 10PPI filters for preliminary harsh purification. They eliminate large slag chunks. Usage 20PPI filters for general spreading needs. They record tool contaminations successfully. Use 30PPI filters for high-precision spreading. They trap extremely fine incorporations.

All densities give exceptional filtration. Metal streams smoothly with the open foam framework. This decreases turbulence. Turbulence triggers issues. The filters capture oxides, slag, various other fragments. Cleaner metal boosts casting quality.

These filters endure extremely high temperatures. They run accurately above 1600 ° C. This matches steel, iron, copper, aluminum casting. The structure stays undamaged under liquified metal pressure. They withstand erosion well.

Checking shows constant efficiency. The filters maintain stamina throughout the pour cycle. They offer excellent dimensional stability. Contraction is minimal during firing and use. This makes certain a dependable suit filter housings.

Applications of Whole 10PPI 20PPI 30PPI Alumina Zirconia Sic Foam Ceramic Filter for Metal Casting

Metal spreading needs tidy fluid metal. Contaminations create weak points or openings in finished parts. Alumina zirconia SiC foam ceramic filters address this problem. These filters catch dust before steel gets in the mold cavity. Alumina gives stamina and handles high warmth. Zirconia includes toughness against thermal shock. Silicon carbide boosts wear resistance and chemical security. With each other they make a really long lasting filter.

The filter resembles a sponge. Metal moves via its several open pores. Solid bits like sand, slag, or oxides get captured inside the foam framework. Just tidy metal travels through. This leads to much better top quality spreadings with less issues. You see much less scrap and rework. Spreadings are more powerful and look far better.

Different pore sizes suit different demands. PPI means pores per inch. A 10PPI filter has larger pores. It permits much faster metal flow. Utilize it for rough cleansing on big, thick castings where speed matters. A 30PPI filter has very little pores. It catches the tiniest dust bits. Select it for vital thin-walled components needing extreme cleanliness. A 20PPI filter offers a middle choice. It stabilizes great dirt removal and decent circulation speed for numerous typical work.

Place the filter in eviction system. Normally put it right prior to the mold tooth cavity. Liquid metal goes into the filter box. It presses with the ceramic foam block. Dust stays entraped in the foam. Tidy steel departures right into the mold. These filters work for iron, steel, aluminum, and other steels. They handle the extreme warmth of molten metal without damaging down. Using the best PPI filter improves your casting yield and component efficiency considerably. It saves money and improves reliability.

5 FAQs of Whole 10PPI 20PPI 30PPI Alumina Zirconia Sic Foam Ceramic Filter for Metal Casting

What are these ceramic foam filters? They trap impurities in molten metal. Whole 10PPI, 20PPI, 30PPI Alumina Zirconia Sic Foam Filters are porous blocks made from a special ceramic mix. You place them in the metal path before casting. They catch dirt and slag floating in the liquid metal. This results in cleaner final castings.

How do these filters actually work? Molten metal flows through the filter’s tiny pores. Solid impurities get stuck inside these pores. The filter acts like a sieve. Only clean metal passes through to the mold. The ceramic material withstands the extreme heat easily.

What’s the difference between 10PPI, 20PPI, and 30PPI? PPI means pores per inch. A 10PPI filter has larger pores and fewer of them. It catches bigger impurities. A 30PPI filter has many more, much smaller pores. It traps finer particles. 20PPI sits in the middle. Choose based on how clean your metal needs to be.

Why use these specific Alumina Zirconia Sic filters? This ceramic mix is very tough. It handles high temperatures and doesn’t react with most molten metals. It lasts well during pouring. Using them means fewer casting defects. You get less scrap metal. Cast parts are stronger and look better.

How do I use the filter correctly? Place the filter firmly in the filter box or gating system. Make sure it fits snugly with no gaps. Preheat it properly before pouring metal. This stops thermal shock cracking. Position it so all metal flows through it. Replace it regularly.
