High Speed Wear Resistant Corrugating Pressure Roll
Pressure roll is beneath the corrugating roll. It exerts pressure upon the lower corrugating roll, which sticks the cardboard paper and the top of the corrugating roll tightly. Because of the direct touch between the surface of pressure roll and cardboard paper, the surface of pressure roll should be cleaned frequently.

High Hardness from Vertical Quenching Process
Intermediate frequency quenching can guarantee both the hardness and harden depth we need. Our harden layer depth can reach to 8-10mm. With harder base material as foundation, the lifetime of our pressure rolls are greatly extended.
