We manufactures custom technical ceramic parts and components, covering a wide range of customer reuquirements. We make use of several forming and machining techniques to process components made from alumina, zirconiz, cordierite. These materials may be used in applications that require wear or coorosion resistance. High temperature capability, or ceramic insulators for electrical resistance.
