1. Selection of extruder

1) Reasonable matching of extruder models;

2) High filling formula should be equipped with high shear screws;

3) Vacuum is used to improve the vacuum degree and reduce the volatile components of materials;

4) Heating and cooling system to prevent the material from being over-molded;

2. Extrusion mold matching

1) The amount of extrusion matched with the extruder

2) The appropriate compression ratio of the split cone of the extrusion die head to reduce mold expansion:

3) Setting the temperature of the die forming plate;
