• Regen­er­a­tion of twin-screw cylin­ders

WAFO has developed a process to regenerate twin-screw cylinders

After regeneration, the cylinders are restored to their original dimensions. The process can be used for all sizes. Both conical and parallel twin barrels can be regenerated. 


Regeneration can be carried out at approx. 65% of the cost of a new cylinder.


The cylinders are welded on the inside along their entire length using a special device and a PTA torch.
A diluted nitriding steel is used as the welding material, which can be nitrided for a long time after application and finishing, just like a new cylinder.


WAFO guarantees that the regenerated cylinders are of the same quality as a new cylinder.
