Absolute world first at WAFO

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. 

Advantage:

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

Process:

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.

Guarantee:

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