    Product Introduction

    DSC07785

    Nitriding screw barrel is a kind of screw barrel after nitrogen treatment, which has excellent wear resistance, corrosion resistance and fatigue resistance, and is suitable for some special process requirements and high-demand processing fields. The following are some nitriding screw barrel applications: Extruders: Nitriding screw barrels are often used in plastic extruders and rubber extruders to process products made of various plastics, rubbers and composite materials, such as plastic films, pipes, plates, profiles, etc.

    Injection molding machine: Nitriding screw barrels are also widely used in injection molding machines for processing various plastic products, including plastic parts, containers, molds, etc. Stirring equipment: Due to the wear resistance and corrosion resistance of the nitriding screw barrel, it can also be used in some special mixing equipment, such as high temperature mixers, chemical reaction mixing equipment, etc. Food processing equipment: In the food processing industry, nitriding screw barrels are often used in extruders and injection molding machines for processing food packaging materials, food containers, etc. Medical devices: The corrosion resistance of nitrided screw and barrel makes it suitable for use in the manufacturing process of medical devices, such as syringes, infusion tubes, etc. In conclusion, nitriding screw barrels are mainly used in the fields of extruders, injection molding machines, mixing equipment, food processing equipment, and medical equipment. In these fields, it can meet special process requirements and high-demand processing needs, ensuring Product quality and production efficiency.
