2000mm Shengli Tungsten Carbide Corrugating Rolls Fingerless Single Facer

Corrugating roll is one of the most important components in corrugated carton production. Usually, it is an essential part of single facer. Corrugating rolls consist of two parts: upper roll and lower roll. The lower corrugating roll is the driving roll, which is generally fixed while the upper one is the driven roll.

Durable from Supersonic Tungsten Carbide Spraying

Tungsten carbide corrugated roller producing technology is different traditional corrugated roll. Because of the particularity of tungsten carbide material, the requirement of the base material hardness is higher, flute profile before tungsten carbide spraying is more precise, which is needed to match the performance of tungsten carbide. Spraying technology is the key, which can ensure the hardness and binding force of tungsten carbide.Most advanced Praxair JP 8000 HVOF tungsten carbide spraying equipment and technology is adopted and Praxair 1342 super hard tungsten carbide powder is used for our corrugating roll. Before tungsten carbide spraying, we do sand blasting treatment on the surface which make rough surface to increase adhesion of tungsten carbide powder.

Repeatedly Polished, Smooth As a Mirror

Meijia adopts special polishing crafts, such as the corrugated rollers use America Praxair 1342VM series super hard tungsten carbide roller, special customized polishing wheel. With our company’s fully automatic CNC corrugated roller producing process’s special polishing machine and our independent grinding polishing technology R&D, the tungsten carbide roller’ s surface finish degree can reach Ra<0.6μm, which will improve the accuracy of the flute profile, and make sure the quality of the corrugated roller.
