MELT TEMPERATURE HOMOGENEITY IN SINGLE SCREW EXTRUSION: EFFECT OF MATERIAL TYPE AND SCREW GEOMETRY

摘要

Thermocouple meshes have successfully been used to measure melt temperature across the material exiting from a 60mm single screw extruder. Temperature profiles are shown to be dependent on screw geometry, set wall temperatures, throughput and material type. Differences in average temperature profile and transient fluctuations have been determined.
