*    We choose the best Zirconia powder and utilize a COLD ISOSTATIC PRESSING system to form shapes. Isotactic pressing is the method of creating ceramic blocks from dry powder and applying uniform pressure from all directions.

*    The process involves enclosing the powder into a deformable mold and collapsing the mold using a fluid medium to apply hydrostatic pressure.

*    The main advantage of isotactic pressing is the uniform application of pressure, which leads to a very homogeneous density and shrinkage, yielding a very reproducible process.

*    The production cost by using isotactic pressing is much higher than UNIAXEL DRY PRESSING. But the quality is also much higher. All Zirconia blocks come with a lifetime warranty Zirconia Blocks Color
