Mold compression control process for an injection molding machine and apparatus thereof |
摘要 |
A method and apparatus controlling an injection molding machine having a compression process. The velocity is controlled using a closed loop single or multi-step programmed velocity control method or a closed loop multi-step programmed slope velocity control method. Pressure may be controlled using a multi-step programmed pressure control method in which a pressure signal is detected from a detector set in the mold die or set in the clamping cylinder. The method of the present invention improves the accuracy and density of articles molded.
