INJECTION-MOLDING MACHINE AND METHOD OF SUPPLYING MATERIALS USING THE SAME, CAPABLE OF ENHANCING INJECTION-MOLDING QUALITY BY CONTROLLING THE SUPPLY OF MATERIALS DEPENDING ON THE OPERATION OF A MAIN SCREW IN A MEASURING PROCESS

摘要

PURPOSE: An injection-molding machine and a method of supplying materials using the same are provided to prevent mixing of gas into an injection-molding product and soot since plasticization instability due to change of driving force of a main screw caused by excessive supply of materials in a measuring process does not occur.;CONSTITUTION: An injection-molding machine comprises a position sensor(45) and a control unit(50). The position sensor detects the position of a main screw(23) in a measuring process. A motor(37) rotates the material transferring screw(34) of a material supply unit(30) and the control unit controls the RPM of the motor depending on the detected position of the main screw to control the amount of materials supplied from the material supply unit to an injection machine.;COPYRIGHT KIPO 2012
