Abstract: The melting behavior of the plastics in iniection and extrusion screws was discussed and com-pared.The influences of processing conditions and screw structure on the melting behavior were studied. The position of melting delay and the axial temperature difference along injection screws were deter mined and correlated with processing conditions like back pressure, rotation rate, temperature, and reservation time. Proper structures for screws with high efficiency were suggested
