1. The size of the output or the specification of the extruder used (the range of output needs to be clear);

2. Requirements for the inlet and outlet pressures of the melt pump (it is necessary to clearly define the pressure range of the conveyed material);

3. What specific fields are applied to (such as composite, sheet/film extrusion, rubber extrusion, etc.);

4. Type and viscosity of transported polymers (such as PP, PET, HDPE, etc.);

5. Requirements for conveying temperature (low, high, normal);

6. The filler content of the conveyed material (percentage and type of filler/solid).
