The hydraulic system including high-speed injection parts of injection molding machine has been developed.The simulation model for high-speed injection system was obtained by u-sing AMESim software.The influence of key parameters is analyzed in electro-hydraulic servo system in terms of dynamic control effect of screw during injection process.Both the control strat-egy and implementation method of electro-hydraulic position-speed servo system are introduced. The control of double variables for the injection position and speed is realized in the same system and the optimal simulation results have been obtained.
