| Abstract: | Injection molding process exhibits complicated process behaviors during start-ups.It is prone to subject to various disturbances,process malfunctions or even faults in that period.An online performance monitoring and fault diagnosis method was applied to injection molding to save production resources and improve production efficiency.Two-dimensional dynamic multivariable statistical model was built for barrel temperatures,based on which,the online monitoring and fault diagnosis method could effectively detect and identify the commonly occurred heating coil faults and sensor faults during process start-ups. |
