We manufacture customized technical ceramic parts and components, covering a wide range of series. We adopt advanced forming and machining techniques to process components made from alumina, zirconiz, cordierite. These materials can be used in applications which require wear and corrosion resistance, high temperature property, or ceramic insulators for electrical resistance.
