Nanjing, China — [ZHITIAN Extrusion Technology]
In the twin screw extrusion industry, screw elements are among the most critical components determining mixing efficiency, throughput, and product quality. With the continuous demand for higher precision and durability, precision machining has become a key factor in ensuring the superior performance of screw elements.
Twin screw extruder screw elements operate under extreme conditions such as high torque, pressure, and temperature. Even the smallest deviation in size, geometry, or surface finish can significantly impact the extrusion process, causing inefficiencies or premature wear. Precision machining ensures that each screw element achieves tight tolerances, accurate geometry, and smooth surface finishes to guarantee optimal performance.
ZHITIAN applies state-of-the-art CNC machining, multi-axis grinding, and strict quality inspection processes to achieve micron-level tolerances. Combined with surface treatment technologies such as nitriding, laser cladding, and HIP materials, ZHITIAN delivers screw elements with exceptional wear and corrosion resistance.
As extrusion technology evolves, precision machining will continue to play a pivotal role in improving efficiency, reliability, and sustainability in twin screw extruder systems. By integrating advanced machining techniques and high-grade materials, ZHITIAN ensures its screw elements not only meet but exceed customer expectations worldwide.
