CONTROL SYSTEM FOR INJECTION MOLDING

摘要

An injection molding apparatus and a control method are provided. The apparatus may include a barrel connected to a hopper for receiving a material from the hopper. The apparatus may include one or more heaters outside the barrel. The apparatus may include an extrusion screw inside the barrel. The apparatus may include a motor coupled to one end of the extrusion screw to rotate the extrusion screw and a torque sensor on the motor. The apparatus may include a controller coupled to the motor and the heaters. The controller may be configured to receive signals from the torque sensor. The controller may include a control algorithm to adjust the one or more heaters according to the signal from the torque sensor to melt the material inside the barrel.
