Grinded corrugated rollers require further surface treatment, such as tungsten carbide spraying or hard chromium plating. Before the surface treatment of corrugated rollers, iit is needed to check the size, hardness, precision, flute profile, and simulation feeding paper. Special projector is used to check the flute profile and feeding different GSM paper to ensure the performance of corrugating rolls. So that each group of corrugated rollers successfully completing their mission can be ensured.
