  • Method of controlling electric injection unit of injection molding machine
    Patent number: 6325954
    Abstract: An injection speed control procedure is applied to controlling an injection screw included in an electric injection molding machine and driven by an electric motor. An injection process is divided into a plurality of injection stages. Injection speed at which the injection screw is moved is changed at a time point when a value PS obtained by integrating injection pressure with respect to the position of the injection screw or a value PT obtained by integrating injection pressure with respect to injection time coincides with a predetermined reference value determined for each injection stage.
