Ultrasound-based monitoring of the plasticizing process in injection moulding machines

Description

In an injection moulding process solid polymer granules are plasticized in a heated barrel containing a rotating screw and stored in the screw ante-chamber. The temperature of the polymer melt stored in the screw ante-chamber after the plasticization should be homogeneous. However, in reality the polymer melt in the screw ante-chamber is not homogeneous due to the complex thermal history of the polymer during the plasticizing in the channel of the screw. We developed two different systems based on ultrasound for the non-invasive monitoring of the plasticizing process along the screw and measuring temperature gradients in the screw ante-chamber.
