Plastic extruder gear melt pump - metering pump

Optimizing plastic extrusion processes - unleashing the power of an extruder gear pump/metering melt pump in sheet, pipe, film, and tube production lines.

Melt pump can also be called a polymer pump, extrusion gear pump, or metering pump.
It is used in various plastic extrusion lines, including sheet, film, tube, cable, pipe, and profile production lines.
Its main function is to control melt flow and regulate pressure to achieve consistent product quality.

A complete melt pump set includes the melt pump body, drive system, and control system. The drive system consists of a motor and reducer that drive the pump shaft rotation. The control system is composed of electrical components and is mainly used to control pump speed, temperature, and pressure.

An extruder gear pump is used on the extruder for transporting and metering high-temperature, high-viscosity polymer melt. At the same time, it increases and stabilizes the pressure of material from the extruder and then transports it to the die. Its stabilizing and metering performance for various plastics is better than in standard extrusion alone.

Melt pumps are widely used in extrusion molding in the plastics, resin, and rubber industries. They are essential parts of extrusion equipment used in granulation, film, pipe, plate, sheet, and other applications, and can be applied for PP, PS, PET, PVC, ABS, PE, PA, rubber, etc.
