Screw elements are key components in extruders, and their design and material selection have a direct impact on the performance and efficiency of the entire machine.
When evaluating the quality and suitability of screw elements, wear and corrosion resistance are two crucial indicators. Wear resistance determines the ability of screw elements, to resist wear during long periods of operation, which affects their service life and maintenance frequency.
Corrosion resistance is related to the stability of screw elements, in different chemical environments, especially when dealing with more corrosive materials, this performance of corrosion resistance is particularly critical.
Therefore, a high-quality screw elements not only need to have good mechanical properties, but also should be excellent in terms of wear and corrosion resistance to ensure efficient and stable operation of the extruder.

Processing Features and Advantages

All component materials used are from either domestic first-line brands or professional material suppliers of Europe. Elemental and metallographic analysis and inspection are conducted to ensure foolproof raw materials. The internal splines of all components are checked with a spline plug gauge to guarantee interchangeability. All parts are made by the most advanced CNC machining center, and CNC grinding is adopted after heat treatment, and the shape error is controlled within ±0.015. Kneading block spacing and sheet thickness tolerances are maintained within ±0.03, length tolerance within ±0.01, and surface roughness of the shape is less than or equal to Ra0.8. This eliminates the impact of heat treatment deformation on component quality.
