Plasticizing Screw - Most of the screws are made using Nitraded steel (EN-41B), chrome alloy steel, H-13 tool steel or stainless steel. Special corrosion-resistant alloys are also available. For each type of screw, we can advise you on a specific profile according to the material processed and its processing conditions. Our engineers are also available to advise you on the choice of steels and treatments.
