  • Plastics processing method and apparatus
    Patent number: 9387619
    Abstract: A method for additive delivery during a plastics processing is disclosed. The method includes establishing a network of components in a control loop that uses a feedback method to drive at least one pump, thus enabling continuous, robust proportioning of additive in a difficult to control environment. The feedback method includes sending at least one signal from at least one sensor associated with a plastics melting machine to a controller, sending one or more signals from the controller to the at least one pump, monitoring the pressure in the at least one pump and sensing the position of an injection nozzle valve, and sending one or more signals to the injection nozzle valve instructing the valve to open or close.
