In the compound processing, it is necessary to guarantee not only the quality of the manufactured product but also the stability of the manufacturing process. In this paper, the construction of the system to manage the operation of extrusion processing was examined. The system developed in conformity with the production process. Only in the display of the measurement value, it is difficult to understand what situation of extrusion processing. The system can have done not only the watch of the state of the processing but also the analysis of the state of the processing. Therefore, it was made to display in the trend graph because it clarified the situation. The system had the function to analyze the situation by the statistical method.
