Plastic extrusion process control method and parameters adjustment system

A parameters adjustment system for a plastic extrusion process, comprising:

• a storage device arranged and configured to store a database and a computer executable command, wherein the database is configured to store a plurality of historical process data of the plastic extrusion process, and each of the historical process data comprises a plurality of critical parameters and a plurality of quality values;
• and
• a processor electrically coupled to the storage device and arranged and configured to execute the computer executable command to perform a plastic extrusion process control method, wherein the plastic extrusion process control method comprises:
• receiving the historical process data from the database;
• dividing each of the critical parameters into a plurality of levels;
• grouping the historical process data according to the levels of the critical parameters to obtain a plurality of parameter sets;
• calculating a quality indicator of each of the parameter sets to build an empirical response surface according to the historical process data corresponding to the parameter sets;
• and
• configuring the critical parameters of the plastic extrusion process to an automatic manufacturing system according to the empirical response surface, such that the automatic manufacturing system performs the plastic extrusion process according to the critical parameters.
