Specification of China Made 10 – 60 Ppi Molten Metal Liquid Filtration Open-cell Reticulated White Alumina Ceramic Foam Filter Plate

This filter plate is made in China. It filters molten metal liquids. The filter uses white alumina ceramic foam. This material is strong and durable. It has an open-cell structure. This structure is a network of connected pores. The pores let liquid metal flow through. The filter traps solid impurities. Impurities include slag and oxides. These impurities are removed before casting. The filter improves metal quality. It reduces defects in cast parts.

The filter plate comes in various PPI grades. PPI means pores per inch. The range is 10 to 60 PPI. Lower PPI means larger pores. Higher PPI means smaller pores. Choose the PPI based on your metal. Thicker metals need coarse filters. Finer metals need fine filters. Common applications include aluminum, iron, copper, and zinc alloys.

White alumina ceramic offers advantages. It withstands intense heat. It handles high pouring temperatures. It resists thermal shock. Sudden temperature changes won’t crack it easily. The material also resists chemical attack. Molten metal won’t easily corrode it. This ensures long filter life. It provides consistent filtration performance.

The filter plate is pure white. It contains no harmful additives. It won’t pollute the molten metal. It is safe for use. The plate size is customizable. Common sizes are 170x170x50mm, 230x230x50mm, 300x300x50mm, and 400x400x50mm. Other sizes are available. The thickness is usually 50mm. This thickness provides good flow control. It offers effective filtration.

Applications of China Made 10 – 60 Ppi Molten Metal Liquid Filtration Open-cell Reticulated White Alumina Ceramic Foam Filter Plate

China made alumina ceramic foam filters help clean molten metal. These filters catch impurities. They remove slag and oxides from liquid metal. This makes the metal cleaner and better for casting.

The filters have an open-cell structure. This structure looks like a net. Molten metal flows through this net. Solid particles get trapped inside the net. Only clean metal passes through to the mold.

These filters come in different pore sizes. The sizes are measured in PPI. PPI means pores per inch. We offer filters from 10 PPI to 60 PPI. The 10 PPI has larger holes. The 60 PPI has much smaller holes. You choose the PPI based on the metal type.

Smaller PPI filters work well for dense metals. Iron and steel casting often uses 10 to 20 PPI. Larger PPI filters are good for lighter metals. Aluminum and magnesium alloys usually need 30 to 60 PPI. Copper alloys fall somewhere in between.

Using these filters improves castings. You get fewer defects in the final parts. Shrinkage porosity is reduced. Inclusions causing weak spots are removed. This leads to stronger, more reliable products. It saves money by reducing scrap rates.

The filters handle very high heat. Alumina ceramic withstands molten metal temperatures. It does not melt or break down easily. The white color shows it is pure alumina. This purity ensures no contamination.

Foundries use these filters daily. They are placed in the pouring system. Metal flows through them before entering the mold cavity. This step is simple but very effective. It is a key step for quality control.

Many industries rely on these filters. Automotive parts need clean metal. Aerospace components require high integrity. General engineering castings benefit too. Good filtration means better performance.

5 FAQs of China Made 10 – 60 Ppi Molten Metal Liquid Filtration Open-cell Reticulated White Alumina Ceramic Foam Filter Plate

What is this ceramic foam filter plate?
This is a special filter made from white alumina ceramic. It has an open-cell structure full of tiny connected pores. The filter comes from China. It cleans molten metal by catching impurities.

Why use this ceramic foam filter?
Metal factories use these filters during casting. Molten metal flows through the filter before entering the mold. The filter catches slag, oxides, and other junk floating in the hot metal. This makes the metal cleaner. Cleaner metal makes better castings with fewer problems.

What does PPI mean?
PPI stands for Pores Per Inch. It tells you how many holes are in one inch of the filter. A lower PPI like 10 means bigger holes and less filtering. A higher PPI like 60 means smaller holes and finer filtering. Choose the PPI based on your metal type and how clean you need it.

How does the filter improve castings?
The filter removes unwanted particles from the liquid metal. This stops defects in the final cast part. You get fewer holes, cracks, or weak spots. Your castings are stronger and look better. This saves money by reducing waste and rework.

What metals can it filter?
This white alumina filter works for many melted metals. It handles aluminum alloys really well. It also works for other non-ferrous metals like copper, zinc, and their mixes. Check the specific filter grade for your exact metal temperature and chemistry.
