To provide a molding machine system or an injection molding machine which can produce a high accuracy molding.

Since this molding machine system 100 is provided with an isolation member 67 for isolating a dryer 30 and a temperature conditioning machine 50 from the injection molding machine 10 in a proper place excluding a connection part with the injection molding machine 10, the injection molding machine 10 can be prevented from receiving the thermal influence of the dryer 30 and the temperature conditioning machine 50. Therefore, the temperature control of molds 61 and 62 and components related to the operation of these is facilitated. Specifically, the temperatures of the movable parts of the injection molding machine 10 can be stabilized, so that the high accuracy molding MP can be produced in a high yield.
