Abstract
In this paper, the control system for the injection molding machine is designed with the help of PLC and SCADA. The main control part of the machine is the molding and clamping unit. At first, a polymer is inserted with the help of a screw and then heated at temperature 275 ℃ with a heater and for measurement of temperature K-Type thermocouple is used. The molted polymer then pressurized with a screw passed through the nozzle at high pressure. The melted polymer is fed into the clamping unit then the material comes into its shape and with cold water material is cool down then discharge from the clamping unit. We analyzed the process using SCADA. We also focus on the application and procedure for predictive maintenance based on the “mean time to failure statistic” to decrease production losses due to machine breakdown. The “5-Why” study method is used to know the machine condition and main issues.KeywordsInjection MoldingSCADA (supervisory control and data acquisition)PLC (Programmable Logic Control)ESPSPredictive maintenance5 why
