Generally, standard injection molding 
                                        machine uses this proportional pressure 
                                        and speed hydraulic system to control 
                                        each machine action based on its pressure 
                                        and speed setting. This system is the 
                                        simplest type to repair and maintenance 
                                        with few defectives. 
                                      The proportional pressure and speed hydraulic 
                                        system uses SUMITOMO gear pump to ensure 
                                        low noise level, high reliability and 
                                        long service life.  |
