As time goes by, tooling, resins, formulations and simply processing requirements change. In comparison, our screws feature up to 50% more screw surface area and a lower compression ratio than typical extruder screws. This enable a more gentle plastification and better wear resistance. All of our screws are nitrided and coated on the outer diameter with a low COF molybdenum coating, by means of LASER WELDING.

Make extended use of your equipment by upgrading your machine with HMG Extrusions screw technology.

Our screws are made from highly wear resistant nitriding steel and our barrels meet the tightest tolerance specs and help maintaining your production rates at max !

For our twin screw barrels we only use high quality steel and machine it on state of the art manufacturing equipment. The barrels are nitrided, using a proven two step heat treating process, to provide an extra thick, wear resistant layer.

Bimetallic barrels for extra long life are available on demand.

We apply our manufacturing experience to every single piece of equipment we supply

Sizes for screws and barrels range from as small as 35 mm up to more than 160 mm and maximum length of 5 meters. Screw geometries can be customized or made as an exact match
