1. Strict Selection High Quality Material
50CrMo alloy steel is specialized material for manufacturing corrugating rolls. Our raw material shell thickness is more than 70mm, the thicker shell can reduce deformation and keep stability during production.

2. Precision Welding Can Be Inseparable
Both ends of the roller body should be heated to release the size of the inner bored hole. After the spindle heads are put in, the roller body and the spindle heads should be held tightly after natural cooling.When the welding process finished, the work piece shall be put into the furnace for high temperature tempering to reduce stress.
3.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 8-12mm. With harder base material as foundation, the lifetime of our corrugating rolls are greatly extended. After different heat treatment process, the corrugated roller surface becomes more wear-resistant and durable. After heating treatment we cut slots of lower roll though this process needs more time but makes uniform hardness.

4. Rigorous for Precise Grinding
After heat treatment and the cutting slots, the roller shall be put on high precision automatic CNC grinding machine to do finish grinding. By grinding wheel grind each flute several times until the accuracy is within our technical permitted requirement. The Siemens control system play a key role in guarantee the accuracy.

5. Flute Profile
Almost every set of corrugating rolls are needed to be designed and customized separately according to the width, diameter, flute height, corrugated paper GSM, speed and cardboard physical index requirement.


6.Strict Test to Keep Improving
Before and after the surface treatment including tungsten carbide plating or hard chrome coating of corrugating rolls, it 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.
