     The extruded speed is slow, the motor current is too high, and there is friction sound between the screw and barrel.
The main causes are:
The viscosity of the material is too large;
The feed zone temperature is too high;
The screw compression ratio is too large;
Proposed measures:

To increase the stencil aperture, to choose a small mesh size filter (clean); to reduce the temperature of the feed section, appropriately increase the temperature of compression section and metering extruder; use the low compression ratio screw to assure the plasticizing
