Our production capacity for screws and barrels from 18 to 40 mm in diameter (0.7146 inch to 1.48 inch), for a maximum length of 9000 mm (357.3 inches) enables us to almost meet all demands from manufacturers and users. Considering the various types of granules which are converted in modern European plastics technology, the choice of the best type of steel quality becomes a key element in the process of producing a whole range of plastics. Euroviti offers its customers a wide range of steels, specifically adapted to plastics transformation, from tandard nitruration steels for non agressive granules to tempered-steels and bi-metals able to resist abrasion and corrosion phenomena, and finally to special alloys for screws and surface coverings ( P. V. D .) in order to lower friction coefficients.
