摘要

Analyzing single screw extrusion performance is usually a practice of watching the results at the exit end of the machine and guessing as to what is taking place inside the barrel. Pressure transducers, melt thermocouples, and high speed analysis equipment have been used for years by some extrusion engineers, but this practice is not universally understood. The data can be quite useful for op- timizing or troubleshooting extruder problems and is invaluable to screw design efforts, but the method of the measurements are important to the results. Extrusion supervisory systems often measure the data from transducers and thermocouples of trending and reporting functions. These devices must use data acquisition rates that are capable of adequately defining the process.
