corrosion resistance alumina ceramic rings flanges pulley

corrosion resistance alumina ceramic rings flanges pulley Reputation depends on quality,  quality comes from Hard! Alumina Ceramic: Alumina wear-resistant ceramic dry pressing technology is limited to objects with a simple shape and an inner wall thickness of more than 1 mm and a length to diameter ratio of not more than 4:1. The forming method is uniaxial or bidirectional. The press is available in hydraulic or mechanical form and can be semi-automatic or fully automatic. The maximum pressure of the press is 200Mpa. The output can reach 15 to 50 pieces per minute. Since the hydraulic press has a uniform stroke pressure, the height of the pressed parts is different when there is a difference in the filling of the powder. However, the pressure applied by the mechanical press varies depending on how much the powder is filled, which may cause a difference in dimensional shrinkage after sintering, which affects product quality. properties:…
