2025-03-28 Structural Optimization of PVC-Specific Melt Pumps
To address PVCs thermosensitivity and susceptibility to carbonization/decomposition during extrusion, the design of specialized melt pumps achieves high-efficiency adaptation through the following structural optimizations: Flared Inlet Channel Function: Expands the inlet diameter to reduce material entry resistance and minimize localized overheating caused by pressure fluctuations or unstable flow. Advantage: Prevents material accumulation at the inlet, shortens residence time, and reduces thermal degradation risks. Optimized Internal Flow Channel and Gear Structure Channel Design: Employs smo
2025-03-27 Specialized Melt Pump for Extruders: A Critical Equipment in Polymer Industry
In the polymer industry, extruders are the key equipment for producing various plastic products, rubber products, and chemical fiber products. The specialized melt pump for extruders is a vital component of the extruder, responsible for conveying high-viscosity polymer melts from the extruders screw to the mold or the next process stage. The working principle of the melt pump is to transport the melt from a low-pressure area to a high-pressure area through precise gear engagement, thereby achieving pressure boosting and stable conveyance of the melt. This type of pump is characterized by high
2025-03-25 Function and advantages of film extrusion melt pump
The thin film extrusion melt pump is mainly used for the transportation, pressurization, and metering of high-temperature and high viscosity polymer melts, and is a key equipment in the thin film extrusion process. Its function is to pressurize and stabilize the high-temperature plastic melt from the extruder, and then send the flow rate steadily into the extruder head, ensuring the continuity and stability of the film extrusion process. Its advantages are mainly reflected in the following aspects: 1. Improving film size accuracy: Melt pumps can effectively reduce material output instability c
