Customized Twin Screw Extruder Screw Elements to Meet Special Process Needs

In modern extrusion production, screw elements play a critical role in determining product quality, efficiency, and stability. Standard components often cannot fully meet the unique processing requirements of different industries, which makes customized twin screw extruder screw elements an essential solution.

Why Choose Customized Screw Elements?

Customized screw elements allow manufacturers to adjust geometry, material, and surface treatment according to their process needs. Whether the requirement is for improved wear resistance, enhanced corrosion protection, or optimized mixing performance, customized solutions ensure the extruder operates at peak efficiency.

Materials and Precision Processing

High-performance materials such as W6Mo5Cr4V2, 38CrMoAl, Cr12MoV, SKD61, and PM-HIP alloys (SAM26, SAM39, CPM10V, CPM9V) are commonly used to manufacture screw elements. Combined with advanced CNC machining and strict quality control, these materials guarantee durability and dimensional accuracy, ensuring reliable performance in demanding applications.
