ESTCOM CZ - oxidová keramika a.s.
Your Oxide Ceramics Specialists
ESTCOM CZ - oxidová keramika a.s. is based at
the site of Elektroporcelán Louny a.s. which is located west of the Town of
Louny (Louny-západ exit when driving on the Prague-Chomutov Road) in the
foothills of the Central Bohemian Highlands. For better orientation please see
the map.
We continue in the proud tradition of oxide
ceramics production which started here back in 1967 with mullite and
mullite-corundum pyrometric tubes and capillaries. Later on the production
expanded to include a wide range of oxide ceramic products.

Manufacturing process
The main manufacturing processes include vacuum press forming, dry pressing, injection molding, and overflow pressing technology.
Vacuum press forming
Tubes and capillaries for use at up to 1500-1800°C
Dry pressing technology
Sealing elements, made of abrasion-resistant corundum materials, with functional surfaces polished to a roughness Ra of 0.3-0.1 µm and a flatness of up to 0.6 µm
Injection molding technology
Structural and abrasion-resistant corundum parts of a fracture toughness of up to 4.6 MPa, ceramic cores for precise casting made of porous aluminosilicate material containing 80% SiO2
Overflow molding technology
Cups, lids, funnels, heads - all from T 02, LUNIT 20/1350 porous materials.
