Planetary screw and barrel

Planetary screw and barrel are a type of extrusion equipment used in the plastics industry. They consist of a screw and barrel that rotate around a central axis, which creates a planetary motion. This motion allows the material being extruded to be mixed and melted more efficiently, resulting in a more consistent and higher quality product.The screw and barrel are made of high-quality materials such as nitride steel or bimetallic alloys, which provide excellent wear resistance and durability. The planetary motion of the screw and barrel also reduces wear and tear on the equipment,
