Function of plastic extrusion system with melt metering pump

The main functions of adding a melt metering pump to a plastic extrusion system include improving product quality, controlling flow rate, homogenizing the melt, reducing pulsation, reducing extruder load, improving production efficiency, improving product quality, extending equipment life, reducing unit energy consumption, reducing reflux and temperature fluctuations, and increasing extrusion output.

melt metering pump

The melt metering pump plays a key role in plastic extrusion processing, mainly manifested in the following aspects:

Stable pressure: The melt metering pump can provide stable melt pressure and prevent pressure fluctuations, which is crucial for maintaining the stability of the extrusion process and product quality. ‌

Control flow rate: By adjusting the speed of the melt metering pump, the flow rate of the melt can be precisely controlled to ensure consistency during the extrusion process. ‌

Homogenized melt: During the process of conveying the melt, the melt metering pump achieves shear and mixing of the melt through the rotation of gears or screws, thereby improving the uniformity and stability of the melt. ‌

Reduce pulsation: Reduce the pulsation of melt flow rate and improve the quality of extruded products.

Reduce extruder load: Using a melt metering pump can reduce pressure and temperature fluctuations at the feed end of the extruder, reducing the load on the extruder. ‌

Improving production efficiency: Melt metering pumps help improve the production efficiency of extruders by reducing the retention time of materials in the screw barrel and stabilizing the plasticization process. ‌

Improving product quality: Melt metering pumps can reduce the dimensional tolerances of extruded products, decrease waste and scrap rates, and enable ordinary extruders to produce high-precision products.

Extending equipment lifespan: By reducing wear and overuse of the extruder, the melt metering pump helps to extend the lifespan of the equipment.

Reduce unit energy consumption: Using a melt metering pump can improve mixing quality and output, thereby reducing energy consumption per kilogram of material processed. ‌

polymer melt gear pump

Reduce reverse flow and temperature fluctuations: The rotation and meshing of gears can seal the low-pressure chamber, reduce reverse flow, lower processing temperature, and facilitate the establishment of higher output pressure.

Increasing extrusion output: Adding a melt metering pump to the extrusion system can significantly improve product output. ‌

In summary, the melt metering pump plays a crucial role in plastic extrusion systems, not only improving production efficiency and product quality, but also extending the service life of equipment and helping to save energy.
