What is the function of installing a metering melt pump on a small extruder in the laboratory?
An indispensable part of a small extruder with precision extrusion is a melt metering pump, a device that accurately measures flow rate, which can measure the capacity of polymers and increase fluid pressure.
The main role of melt pump for extrusion in laboratory small-scale extrusion systems is:
1. Accurate measurement control;
2. Reduce the impact of screw oscillation;
3. Convey uniformly melted resin to the mold head;
4. Avoid uneven melting density;
5. Improve product quality;
6. Smaller product tolerances;
7. Save on raw materials.
The role of a melt metering pump in extrusion stability is self-evident. In the laboratory stage, after configuring a small extruder with a melt metering pump, it can approach the actual production environment to a large extent and prepare sample samples well, which has a very positive role in guiding the production process.
