What is the application scope of the melt pump for plastic sheet extruders?

The application scope of the melt pump for plastic sheet extruders is quite extensive, mainly covering the following aspects:

Plastic Sheet Extrusion:

During the extrusion process of plastic sheets, the melt pump can ensure a stable supply of melt and eliminate the influence of screw pulsation from the extruder. This helps improve the dimensional accuracy and appearance quality of the sheets, enabling them to perform better in subsequent processing and use.

Plastic Pipe Production:

In the extrusion process of plastic pipes such as PVC, the melt pump can stabilize and pressurize the high-temperature, high-viscosity melt extruded by the extruder and then deliver it stably to the extruder die. This ensures the dimensional accuracy and quality stability of the pipes, improves production efficiency, and reduces scrap rates.

Plastic Film Manufacturing:

The melt pump can precisely control the flow rate and pressure of the melt, making the thickness of the film more uniform and the surface smoother and flatter. This helps improve the quality and performance of the film, meeting the requirements of different application fields for film.

Other Extrusion Molding Applications:

Besides sheets, pipes, and films, melt pumps are also widely used in extrusion molding fields such as plastic plates, artificial fibers, optical fibers, and medical plastic catheters. In these applications, the melt pump can also provide stable melt conveying and pressurizing effects, ensuring the quality and performance of the extruded products.

Pharmaceutical and Food Processing:

In the pharmaceutical and food processing industries, melt pumps are also used to convey high-temperature, high-pressure drugs and food raw materials. This requires the melt pump to have high reliability and stability to ensure product safety and quality.

Other Special Applications:

Melt pumps can also be used in special applications such as co-extrusion, mixing, and precision extrusion. In these applications, the melt pump can provide precise melt metering and conveying effects to meet the production needs of special products.
