Abstract: A reference physical quantity and a current physical quantity are successively compared with each other in association with an elapsed time during which a moving part operates or an operating position of the moving part, and a deviation of the physical quantity is determined. An average of absolute values of the determined deviations of the physical quantities is calculated, and a threshold corresponding to the elapsed time during which the moving part operates or the operating position of the moving part is calculated such that the threshold increases as the calculated absolute value increases. Abnormality is detected if the calculated threshold is exceeded by the determined deviation of the physical quantity.

Abstract: A movable unit in an injection molding machine is started to operate and the current physical quantity and the current time (or current position of the movable unit) are detected. The current physical quantity is stored as a reference physical quantity in association with the elapsed time of operation of the movable unit (or position of the movable unit). A deviation of the current physical quantity from the reference physical quantity is calculated and stored, a distribution index value is then calculated from the physical quantity deviations in the first to n-th cycles, and a threshold value is determined from the distribution index value. When the deviation exceeds the threshold value, alarm processing is performed.

Abstract: A thermoplastic injection molding system and method of use is described for molding parts from heated plastics and other organic resins. The machine uses heat sources located along the barrel to heat the source material while an auger screw transports the source material in the barrel. This transport step does not shear the source material, nor does it use friction to produce the heat necessary to melt the source material. The material becomes substantially liquid or melted during the heating process, and the melted material is forced, by the auger screw, into a chamber whereupon a plunger, situated concentrically with the auger screw, injects the material from the chamber into a mold. Sensors located along the barrel and in the chamber ensure consistency between mold cycles. The controller dynamically adjusts the injection molding process to achieve more consistent and reliable molded parts.
