What is the application scope of PE packaging board extrusion melt pump?

The application scope of the PE packaging board extrusion melt pump is extensive, mainly embodied in the following aspects:

1.Material Processing

High-temperature and High-viscosity Polymer Melts: The melt pump is primarily used for conveying, pressurizing, and metering high-temperature and high-viscosity polymer melts, such as PE (polyethylene). These materials require stable pressure and flow control during the extrusion process to ensure product quality and consistency.

Versatility with Multiple Polymer Materials: In addition to PE, the melt pump can also process other polymeric materials like PC (polycarbonate), PP (polypropylene), PVC (polyvinyl chloride), HIPS (high-impact polystyrene), PS (polystyrene), PA (nylon), and TPUR (thermoplastic polyurethane rubber). This versatility grants the melt pump significant potential for widespread application in the plastics processing industry.

2.Production Line Applications

Extrusion Molding Lines: The melt pump is widely utilized in plastic extrusion molding lines for the production of various products, including granules, films, pipes, boards, sheets, and more. In the production of PE packaging boards, the melt pump ensures a stable pressure and flow of the melt into the extruder head, enhancing product dimensional accuracy and surface quality.

Compounding and Extrusion Granulation Lines: Combining a co-rotating twin-screw extruder with a melt pump into a compounding and extrusion granulation line significantly improves mixing quality and output. This configuration is particularly suitable for scenarios requiring high-precision and high-quality extruded products.

3.Functional Characteristics

Stable Extrusion: The melt pump eliminates feeding errors from the feeding system and mitigates fluctuations transmitted from upstream processes, making the extrusion process more stable. This contributes to reducing waste rates and improving product dimensional accuracy.

Increased Output and Reduced Energy Consumption: By transferring the pressure reduction function from the extruder to the melt pump, the extruder can operate under low pressure and temperature conditions. This not only enhances productivity but also reduces energy consumption and extends machine life.

Linear Extrusion Characteristics: The conveying capacity of the melt pump is essentially linear with its rotational speed, facilitating coordination with upstream and downstream equipment. By collecting information such as pressure and temperature at the inlet and outlet of the gear pump, online monitoring and feedback control of the entire extrusion process can be achieved.

4.Industry Applications

Plastic Packaging Industry: As one of the essential products in the plastic packaging industry, the stability and consistency during the production of PE packaging boards are crucial to product quality. The application of the melt pump ensures stable melt pressure and flow during the production of PE packaging boards, thereby improving product quality and production efficiency.

Other Related Industries: Beyond the plastic packaging industry, the melt pump is also widely used in other industries related to the processing of polymeric materials, such as chemical fibers, wire and cable manufacturing, wire drawing, and compound extrusion.

In conclusion, the PE packaging board extrusion melt pump boasts a broad application scope and powerful functions, making it an indispensable piece of equipment in the plastics processing industry.
