Estcom Cz – Oxidová Keramika A.S.

We continue in the production of oxide ceramics, which has the tradition in area since 1967. The first products produced in the plant were pyrometric tubes and capillaries made of mullite or mullite-alumina ceramics. Further new products were put into production and the assortments of oxide ceramics were extended too. Technology The main production processes are the technology of vacuum press extrusion, dry pressing technology, injection casting technology and wet pressing technology. The most important products are through these technologies realised. 1. Extrusion technology on vacuum press machinestubes and capillaries with the working temperature 1500 – 1800 °C 2. Dry pressing technology seal elements made of high alumina ceramics with good abrasion resistance. Working surfaces are cut and polished up to toughness Ra 0.3 – 0.1 µm with flatness up to 0.6 µm 3. Injection moulding technology construction alumina parts of abrasion resistant materials with fracture toughness up to 4.6 MPa, ceramic cores for precision casting process made of porous aluminosiliceous ceramics containing 80% SiO2 4. Wet pressing technology crucubles, lids, funnels, heads of porous materials T 02, LUNIT 20/1350 Ceramic substances and materials 1. Dense mulite ceramics trade mark Lunit 73 (see IEC 672 C 610) 2. Mulite-alumina ceramics trade mark Lunit 20 (see IEC 672 C 530) 3. Dense high alumina ceramics trade mark Luxal 203 (see IEC 672 C 799) 4. Dense high alumina ceramics trade mark AG 202 (contents IEC 672 C 795) 5. Porous alumino-silicate ceramics trade mark Lusil (obsah SiO2 80%) 6. Porous siliceous ceramics trade mark T 02 (contents SiO2 80%) 7. Equipment for industrial laboratories Our products include the following: Tubes, rods and capillaries, fibre, crucibles, construction parts and cores --- We are first and foremost a manufacturing company.
