Professional Manufacturer and Exporter of Ceramic Foam Filter In China

Hebei CangChen, a professional manufacturer of foundry filtration products, specializes in research & development, production, sales, service and solutions.

We are the recognized leader in the development and production of casting filters at home and abroad, and possesses the excellent innovation and customization capabilities in filter manufacturing technology.

For Ceramic foam filters, Four kinds of materials at our factory now, Let's see what they are!

1. SIC Ceramic Foam Filter

Silicon carbide ceramic foam filter adopts Japan imported polyurethane foam sponge as the carrier, the slurry which mainly contains silicon carbide is extruded into the foam sponge, and then extrude slurry, the remaining slurry coated around the foam fiber is dring, roasting and sintering at high temperature, polyurethane is decomposed by heat, foam shaped ceramic products are left, namely, silicon carbide(SIC) foam ceramic filter.

● SIC ceramic foam filter with foam sponge three-dimensional mesh interworking structure can make the metal liquid reflect the rectification, mechanical screening, filter cake, adsorption filtration mechanism to effectively improve the purity of metal liquid, reduce scrap rate, reduce machining losses so as to improve production efficiency and reduce production costs.

● SIC ceramic foam filter has the characteristics of high strength, good thermal stability, large specific surface area and high dimensional accuracy.

● SIC ceramic foam filter mainly used for filtering and purifying nodular cast iron, gray cast iron, copper and other alloy metal liquid filtration.

2. Alumia Ceramic Foam Filter

Alumina foam ceramic is a kind of foam material made from high purity alumina. The foam ceramics have the characteristics of uniform porosity, high temperature resistance, heat shock resistance, wear resistance and chemical stability.

● Widely used in casting processing, water treatment, chemical industry, environmental protection and other industries. It is the ideal liquid aluminum filter; Catalyst support, and good sound insulation, thermal insulation material. Product shapes, sizes, and voids PPI can be designed and manufactured on request.

● Alumina foam ceramic filter plate is very important to the quality of aluminum melt, which affects the subsequent processing performance and the quality of final products to a great extent.

● Therefore, all countries in the world attach great importance to the purification of aluminum melt.

3. Zirconia Ceramic Foam Filter

The basic material of zirconia foam ceramic filter is ZrO2. The heat resistance temperature higher than about 1760℃, and it has very high strength and excellent high-temperature impact resistance.

● Cast steel parts are widely used in aspects that require high strength and elongation requirements. Therefore, cast steel parts are very sensitive to defects caused by impurities.

● The excellent characteristics of the zirconia Ceramic Foam Filter can effectively remove impurities that ultimately lead to product quality defects.

● The impurities mainly consist of non-metallic particles, slag, and refractory material fragments.

● It improves the surface quality and mechanical properties of the casting parts, reduces the scrap rate. 

● The zirconia Ceramic Foam Filter can make the molten steel fill the cavity more uniformly.

● During pouring, the molten metal has a higher tendency for turbulence, and the turbulence after passing through the three-dimensional pore structure of the zirconia Ceramic Foam Filter is ultimately converted into a very stable laminar flow. The laminar flow has better filling properties for the cavity, thereby reducing the impact and corrosion of the molten metal solution on the casting cavity and significantly reducing the scrap rate.

4. Honeycomb extruded ceramic filter

Honeycomb extruded ceramic filter is a kind of porous industrial ceramic with an internal structure of many parallel channels in the shape of honeycombs, which are divided by thin interlayers in a grid-like pattern. It is widely used in the metallurgical and foundry industries for filtering molten metal substances.

Produced based Mullite with kinds of hole sizes, which can withstand heavy pouring thermal shock and extreme pouring temperature.

● The extruded ceramic filters have excellent properties of precise dimension, good thermal stability, high specific surface area and resistance to acid and alkali.

● The cellular design also provides an engineered balance between flow rate and strength and it can effectively capture inclusions and reduce turbulence of the molten metal.

● It has a large metal flow rate and quite stable (different from ceramic foam filter whose flow rate gradually decreases with the increase of the number of inclusions being captured). Even if there is much inclusions in the filter, the normal use will not be influenced.

● Widely used for ferrous and non-ferrous metal castings, ductile iron, gray cast iron, aluminum casting.

After more than ten years' export experience, we continue to update and iteration. We manufacturing enterprises focusing on foundry filtration products, mainly for foundries and private brand importers or want to start their foundry business customize products and provide OEM services.

Providing & customizing the most suitable filters with the best service is the ultimate goal of Hebei CangChen.

"Always Better" is our Business Philosophy.
