What are the application scenarios of plastic granulation melt pumps?

Plastic granulation melt pumps are primarily used for the conveyance, pressurization, and metering of high-temperature, high-viscosity polymer melts, playing a crucial role in the plastic granulation and related fields. Below is a detailed summary of their application scenarios:

I. Plastic Granulation Industry

Raw Material Conveyance and Pressurization

Plastic granulation melt pumps can stably and efficiently convey molten plastic raw materials to the die head of the granulator and ensure sufficient pressure to meet the needs of the granulation process.

Precise Metering and Control

During the granulation process, melt pumps can precisely meter the flow rate of molten plastic, thereby ensuring that the weight and size of each plastic particle meet standards, improving product quality and consistency.

II. Extrusion Molding Field

Production of Films, Tubes, and Sheets

In production lines for plastic films, tubes, and sheets, melt pumps are often used to pressurize and stabilize molten plastic raw materials before sending them to the extruder die head, ensuring stability and continuity in the extrusion process, thereby improving product quality and production efficiency.

Co-extrusion and Multi-layer Co-extrusion

In co-extrusion and multi-layer co-extrusion production processes, melt pumps can precisely control and convey different types of molten plastic raw materials, ensuring adhesion and overall quality between layers.

III. Chemical Fiber and Medical Plastic Tubing Industries

Chemical Fiber Production

In the production of chemical fibers, melt pumps are used to stably convey molten chemical fiber raw materials to the spinning die head, ensuring stability and continuity in the spinning process, improving the quality and output of chemical fibers.

Manufacture of Medical Plastic Tubing

Medical plastic tubing has extremely high quality and precision requirements. Melt pumps can ensure stable conveyance and precise metering of molten plastic raw materials, thereby manufacturing tubing products that meet medical standards.

IV. Other Application Scenarios

Wire and Cable Production

In the production process of wire and cable, melt pumps are used to stably convey molten plastic insulating materials to the extruder die head, ensuring the quality and uniform thickness of the insulating layer of wire and cable.

Wood-Plastic Composite Profiles Production Line

Wood-plastic composite profiles are a new type of environmentally friendly material, and melt pumps are also used in their production process to convey and pressurize molten wood-plastic raw materials.

In summary, plastic granulation melt pumps have wide applications in various fields such as plastic granulation, extrusion molding, chemical fibers and medical plastic tubing, as well as wire and cable production. Their ability to stabilize melt pressure and flow rate, along with precise metering characteristics, significantly enhances product quality and production efficiency in these fields.
