The twin-screw extruder, with its excellent material conveying, mixing plasticization, and shear dispersion capabilities, has become the core equipment for the production of various types of masterbatch such as color masterbatch, filling masterbatch, and functional masterbatch. The quality stability (such as dispersion uniformity, particle size consistency), performance compliance rate, and production efficiency of masterbatch products…

As a core equipment in the field of polymer material processing, the stability of the extrusion output of the twin-screw extruder directly determines the consistency of product quality, production efficiency, and production costs. In actual production, fluctuations in extrusion output are a common problem, which not only lead to deviations in product dimensions and uneven…

As a core equipment in polymer processing, the twin-screw extruder is widely used in plastic modification, profile extrusion, composite material preparation and other fields. The die head, as a key component for material molding and output, its discharge status directly determines the product quality and production efficiency. In actual production, unsmooth discharge or blockage at…

Abstract: The extrusion system of a twin-screw extruder is the core unit for plasticizing, mixing, and conveying materials. Its faults directly lead to product defects (such as rough surfaces, bubbles, and strand breaks), production interruptions, and equipment loss. This document focuses on 7 core fault types including temperature abnormality and pressure fluctuation, detailing specific fault…

As the core power source of the twin-screw extruder, the operational stability of the main motor directly determines the production efficiency, product quality, and service life of the extruder. Under long-term high-load and continuous operation conditions, the main motor is prone to various faults affected by multiple factors such as process parameters, operating specifications, and…
