Structure and Function of Twin Screw Extruder Parts: A Focus on the Screw Barrel

A twin screw barrel, critical in twin screw extruder parts manufacturing, is divided into three essential functional sections: the feeding section, compression section, and homogenization section (also referred to as the metering section). Each of these sections is designed with specific features, such as varying groove depths and transitions in the screw diameter, to optimize extrusion performance.

Feeding Section:
In this section, the groove depth remains constant, which allows for the preheating and consistent transport of the solid plastic material. The plastic material must begin to melt by the end of this section for smooth functioning, which is crucial for any screw barrel manufacturer aiming to provide high-efficiency solutions for extruder systems.

Compression Section

The groove depth decreases progressively in this section, allowing the plastic raw material to melt, mix, and undergo shear compression. This section is key in reducing the plastic volume and managing pressure buildup, which is why the compression ratio becomes a vital design parameter in twin screw barrels. Optimizing this ratio ensures that the plastic is properly melted, compressed, and vented.

Homogenization Section

Also known as the metering section, the homogenization section maintains a fixed groove depth. Its primary purpose is to ensure proper mixing, transportation, and measurement of the molten plastic. Adequate pressure must be provided to keep the temperature uniform and ensure a stable flow of molten plastic, a vital feature in twin screw extruder parts used for high-precision applications.
