Bad plasticizing before extrusion, the wire surface has hairy and no gloss, or even appear like a toad skin, or there is an obvious line at the adhesion of extruded layer

Main reasons:
The set temperature is too low, especially at the die;
improper operation, the screw and traction is too fast, the material is not fully plasticizing.
Uneven mixing of the material in granulation or the material has itself quality problems;
proposed measures:

To improve the body and die temperature; to reduce the screw speed and traction speed; replace the material
