The Crucial Role of Melt Pumps in Polymer Extrusion Molding
A melt pump is a power equipment used for conveying high-temperature, high-viscosity polymer melts. It plays a pivotal role in the extrusion molding processes of plastics, resins, rubbers, and chemical fiber products. The following is an overview of its functions and applications:
In terms of functionality, melt pumps are primarily used for conveying, pressurizing, and metering high-temperature, high-viscosity polymer melts. They can pressurize and stabilize the high-temperature plastic melts from extruders and then deliver them with a stable flow rate to the extruder die. Their ability to stabilize melt pressure and flow rate surpasses that of various types of extruders.
Melt pumps can also effectively isolate the impact of pressure and flow fluctuations in the feed zone on the discharge zone, achieving stable flow conveyance. Additionally, by adjusting the pump's rotational speed, melt pumps can achieve precise flow control, which is crucial for producing high-quality products.
Overall, melt pumps play a significant role in the extrusion molding processes of plastics, resins, rubbers, and other products due to their characteristics of stable conveyance, precise control, and high efficiency and energy saving. They have brought remarkable economic benefits to related industries.
