Productive Technology:

   Wearable ceramic is the special corundum ceramic that has been sintered under 1800°C with the main raw material of Al2O3 and flux of rare metal oxide.Using the high strength organic/inorganic bond to felt together, and then grinding to the size as drawing required.

Advantages:

   1.High temperature

   2.Good insulation

   3.High strength

   4.Precision Process

  We can produce ceramic flange according to client's specifications and even by molds

or drawings provided by the client!
