The application fields of melt glue gear pumps (also commonly known as hot melt glue precision gear pumps or melt gear pumps) are quite extensive, mainly including the following aspects:

I. Polymer Production Processes

Resin and Chemical Fiber Industries: Melt glue gear pumps are primarily used in these industries for the reactive transfer of high-temperature, high-viscosity polymer melts, such as the bottom discharge, piping transfer, and pressurization of final polymers like resins and chemical fibers. These pumps are typically large in size, featuring high precision, high reliability, and long service life, making them critical transfer equipment in polymer reaction processes.

Rubber Industry: In the production of rubber products, pump for hot glue melt also play an important role in the transfer and pressurization of rubber base stocks and prepolymers.

II. Chemical Processes

Petroleum, Chemical, Pharmaceutical, and Food Industries: Melt glue gear pumps can be used for the transfer of various pure fluids with a certain viscosity in these industries. Their transfer medium has a wide range of viscosities, capable of adapting to the needs of different operating conditions. In large polymerization plants, gear pumps can also be used for material transfer when the viscosity of the material at the front end of the polymerization reaction is low.

III. Extrusion Systems

Plastic Industry: Gear pump hot melt glue are widely used in plastic extrusion molding processes, such as the production of pellets, films, pipes, sheets, plates, and other products. They are usually installed between the extruder outlet and the die head to boost pressure, stabilize pressure, and meter the material, ensuring the thickness, uniformity, and dimensional accuracy of the products.

Other Extrusion Industries: For example, in cable manufacturing, they transfer and pressurize insulating and sheathing materials to ensure cable performance and quality. In co-extrusion and mixing processes, melt glue gear pumps can precisely control the raw material ratio and mixing uniformity, safeguarding the performance and quality of the final product.

IV. Other Applications

Melt glue gear pumps can also be used in various extrusion industries, such as sheet, plate, pipe, film, pelletizing, wire drawing, cable, co-extrusion, mixing, precision extrusion, etc., suitable for the extrusion transfer of polymer melts with viscosities ranging from low to extremely high.

In summary, melt glue gear pumps play an important role in multiple fields due to their high precision, high reliability, and stable performance. With continuous advancements in technology and the expansion of application fields, the performance and applicability of melt glue gear pumps will further improve.
