Main feature of ST zirconia block:
● Select the best Chinse raw materials
● After dry pressed and cold isostatic: balanced pressure, better
strength: better color: more translucent
● More accurate scaling factor (the persistent and consistency of
scaling factor between each batch)
● Reliable, controllable, reusable production process to make sure
produce the products with the same quality.
● Easy to cut, no porcelain breakage, less scraps
● Every block has its barcode easy to control lot size, and it
including information such as scaling factor.
