Abstract:

ACCURATE CONTROL OF THE MOLD INTERIOR SURFACE TEMPERATURE IS CRITICAL FOR QUALITY PRODUCTION OF PLASTIC PARTS: CURRENTLY, MOST OF THE INJECTION MOLDING MACHINES USE OPEN LOOP CONTROL WITHOUT ANY DIRECT MEASUREMENT OF THE MOLD SURFACE TEMPERATURE. THE CONTROL VARIABLES ARE WATER TEMPERATURE AND VALVE SETTINGS FOR THE COOLING/HEATING WATER THAT IS CIRCULATED THROUGH THE MOLD. CLOSED LOOP SYSTEMS WITH THERMOCOUPLE MEASUREMENTS ARE AVAILABLE, BUT PROVIDE LIMITED USEFULNESS. THIS PROJECT DISCUSSES AN INNOVATIVE DESIGN FOR TWO-DIMENSIONAL TEMPERATURE MONITORING AND REGULATION USING AN INFRARD SENSOR, IMAGE PROCESSING, AND ROBUST CONTROLLER DESIGN USING MODERN CONTROL THEORY APPROACHES. EXPERIMENTAL DATA IS BEING COLLECTED TO VALIDATE THE ACCURACY OF TEMPERATURE ESTIMATION USING INFRARED CAMERA, TO IDENTIFY MODELS FOR CONTROLLER DESIGN, AND TO VERIFY THE PERFORMANCE OF THE CLOSED LOOP CONTROLLER.
