Advantages of gear pump in plastic extrusion

When the gear pump in plastic extrusion is used in series with a single screw or twin screw extruder, the benefit of the whole production line can be significantly increased. The main advantages of using melt pumps are:

1. Stable output pressure - can effectively reduce the material output instability and pressure fluctuation caused by extruder parameters.

2. Improving product quality - minimizing dimension tolerance of extruded products and reducing waste and waste rate. Ordinary extruders can also produce high-precision products.

3. Increase the extrusion output-reduce the pressure requirement for screw, from screw to die, to melt pump to die, screw can extrude at high speed and high efficiency, and can adjust the back pressure of extruder, reduce the residence time of melt in the screw barrel, stabilize the plasticizing process, reduce the melting temperature, and improve the output and quality of products.
