1. Plastic Processing Industry

Extrusion Molding: The melt gear pump is often installed between the extruder outlet and the die head, used in the extrusion molding of plastics, resins, and rubber products, such as pelletizing, film, tubing, sheet, and plate production. Its primary roles here are pressure boosting, pressure stabilization, and metering, ensuring that the melt enters the mold with consistent pressure and flow rate, thereby enhancing product quality and production efficiency.

Injection Molding: During the injection molding process, the melt gear pump can deliver molten materials to the mold at a constant pressure, ensuring the stability of the molding quality.

2.Chemical Fiber Industry

The melt gear pump plays a vital role in chemical fiber spinning and other production processes, handling the transportation and pressure boosting of molten materials. It ensures the continuity and stability of the spinning process, improving the quality of chemical fiber products.

3.Rubber Industry

In rubber production, the melt gear pump is utilized to convey molten rubber raw materials and additives. It guarantees the uniformity and stability of rubber products, contributing to enhanced product quality.

4.Chemical Industry

The melt gear pump also finds extensive application in the chemical industry, particularly when it comes to transporting high-viscosity, high-temperature chemical raw materials and products, such as resins and coatings. Its corrosion resistance and high-temperature, high-pressure capabilities enable it to cope with complex chemical production environments.

5.Pharmaceutical Industry

In pharmaceutical processes, the melt gear pump is used to convey various high-viscosity pharmaceutical liquids and solvents. It ensures precise metering and control during drug production, enhancing the quality and safety of pharmaceutical products.

6.Other Industries

In specific production processes within industries like food, textiles, and papermaking, the melt gear pump may also be required to convey specific high-temperature, high-viscosity media.
