     If there are pimples on wire surface?
Causes are:
The set temperature is too low,  the material is not completely plasticized before extruded from the head;
Some impurities is introduced into the feed hopper, causing impurities pimple;
The material itself is poor quality, there is difficult plasticized resin which is not completely plasticizing before extrusion.
Proposed measures:

appropriate to increase the extrusion temperature or reduce the screw and pulling speed; strict inspection of impurities when feeding, and to prevent mixed with other materials; reasonable set the processing temperature, regular cleaning of the extrusion system, to choose a suitable machine and reasonable model to prevent scorch knots; replace the material.
