A melt pump is a power equipment used for conveying high-temperature, high-viscosity polymer melts. It plays a crucial role in the extrusion molding process of plastics, resins, rubbers, and chemical fiber products. Below is an overview of its functions and applications:

In terms of functionality, the melt pump is primarily used for conveying, pressurizing, and metering high-temperature, high-viscosity polymer melts. It can pressurize and stabilize the high-temperature plastic melt from the extruder and deliver it with a stable flow rate to the extruder head. Its ability to stabilize melt pressure and flow rate is superior to various types of extruders. The melt pump can also effectively isolate the impact of pressure and flow fluctuations in the feed area on the discharge area, achieving stable flow conveyance. Furthermore, by adjusting the pump's rotational speed, the melt pump can achieve precise flow control, which is crucial for producing high-quality products.

In terms of applications, melt pumps are widely used in the extrusion molding of plastics, resins, and rubber products, such as granulation, films, pipes, sheets, plates, artificial fibers, optical fibers, medical plastic catheters, etc. They can be used in series with single-screw or co-rotating twin-screw extruders, significantly improving the efficiency of the entire production line. Additionally, combining a co-rotating twin-screw extruder with a melt pump to form a mixing and extrusion granulation production line significantly improves the mixing quality and output compared to standalone twin-screw granulation units, while also reducing energy consumption. By installing a melt pump and extruder heads for pipes, plates, films, etc., on original single-screw or co-rotating twin-screw granulating extruders, the granulation process can be eliminated, directly extruding products, simplifying the production process, and shortening the production cycle.

 

Melt pumps are used for conveying, pressurizing, and metering high-temperature, high-viscosity polymer melts, stabilizing flow rates, and achieving precise control. They are widely applied in the extrusion molding of plastics, resins, and rubber products, improving efficiency, reducing energy consumption, simplifying processes, and bringing significant economic benefits to the industry.
