Isostatic pressing graphite tooth roller

Ceramic Furnace Rollers

The water content of the isostatic pressing roller blank is about 1%, and the forming pressure can be between 80-150 MPa, depending on the blank composition and the diameter and length of the roller blank. The advantage of isostatic pressing is that there is no dry and deform of the blanks, and the strength of the blank is large.
