Introduction
--The largest professional corrugated roller manufacturer in northern of China
--50CrMo refined forging steel supplied by the best manufacturer in China.
--A, C, B, E, F, G, N flute corrugated rolls
--High Speed can reach to 200m/min
--Hard Chrome 0.06-0.08mm
--Medium frequency quenching heating treatment machine makes --the hardness of base steel more than HRC58 and harden layer 8-12mm.
--High precision and high performance CNC grinding machine equipped with Germany Siemens control system.
--We design the flute profile according to customer’s medium paper GSM, speed, FCT requirement. The flute profile is more reasonable, suitable to customer’s machine
--Our corrugated rollers has been exported to many countries such as Korea, Russia, Egypt, India, Thailand, Myanmar, etc.
--Supply corrugated rollers for all kinds of corrugator line such as Fosber, BHS, BW Paper System, K&H, HSIEH HSU,Fuli, Wanlian, TCY, Champion, West River, Mingwei and so on.
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.
