We produce extruded ceramic filter with different appearance specifications, wall thickness, hole type and aperture.
Material: Cordierite, Mullite, Alundum mullite, Zircon mullite.
The advantages of extruded ceramic filter as follows:
Good thermal shock properties.
Uniform hole make metal liquid reduce the swirl, more conducive to change metal liquid from laminar to turbulence.
Accurate extrusion die make product quality extremely stable and consistency.
Extruded ceramic filter is mainly used in filtration molten metal foundries and cast houses. As per client's requirements, we produce a variety of materials, sizes, shapes and apertures of the extruded ceramic filter.
Material: Cordierite and mullite, cordierite/mullite, mullite/zirconia, high aluminum, silicon carbide, and etc.
Application: grey iron and ductile iron, aluminum, aluminum alloy, copper, stainless steel, and etc.
