Screw elements

• The screw elements are processed by CNC thread grinding, and the three-dimensional meshing curve has high precision;
• All mix function are processed by machining centers, with good identity and strong process repeatability;
• The screw elements rotate in the same direction and clean each other, so they have good self-cleaning properties;

• Screw elements with different leads and lengths;

• Mix function at different angles, numbers or thicknesses;
