Using the precision forged hi-quality alloy steel as raw material, the roller surface is sprayed with tungsten carbide, a metal compound with the same hardness as diamond. The service life of tungsten carbide corrugated roll is 3-6 times that of ordinary chrome-plated corrugated roll. Various cardboard shapes with higher strength and lower paper consumption rate can be designed according to customer's requirements. The high hardness and high wear resistance of tungsten carbide make the flute profile more optimized.
◆ Outer suction type corrugating roll with ring shape slot
◆ Inner suction type corrugating roll with cross shape slot
◆ Inner suction type corrugating roll with fishbone shape slot
High durability, high service life.
