A new coating technology is available for twin screw flights (conical and parallel types) based on a Vanadium-Alloy material (Product Specification X-FeCrV15). In combination with HMG Extrusions high quality nitrided barrel the VCr-coated screw flights will increase the lifetime by approx. 1.5 times vs. a standard Mo-coating at the same cost level. The higher wear resistance is achieved due to hard carbides with exceptional metal to metal wear bearing properties. The coating is applied by a LASER WELDING method which ensures a perfect bond to the base material. Take advantage of this new technology for your future purchases of replacement screws and barrels and ask us for an offer or for additional specifications.
