Barrel Refurbishment.


TWS can in most cases refurbish worn extruder barrels by honing parallel oversize and then refurbish the screw to suit the new barrel size, If the barrel is made from En41B it will be re-nitrided to the original hardness, bimetallic barrels do not require re-hardening as the hardness is still present.

If the barrel is too worn to hone out we can manufacture a new replacement barrel in either Nitriding steel (EN41B) or with a bimetallic bore please Click Here
