A control method for an injection moulding system having an extruder, feeding material continuously to an accumulator, portioning material intermittently to an injection device, wherein the control method is configured to drive the extruder at a high speed or at a low speed respectively, the high speed and the low speed defining an extruder speed interval, the method comprising acquiring a value for an actual positional change for the accumulator (POS.sub.ACT), comparing the value for the actual positional change (POS.sub.ACT) with a predicted value for the positional change (POS.sub.PRED), and adjusting a speed of the extruder based on a result of the comparison.

A injection molding method involves measuring, using at least one external sensor, a change in a parameter of a mold side of a mold cavity, approximating a condition within the mold cavity based on the change in the parameter, such as pressure within the mold cavity or flow front position, and comparing the approximated condition to a trigger point,. If the approximated condition equals or exceeds the trigger point, activating a virtual cavity sensor having an optimal pre-defined pressure-time curve, and upon activation, the virtual cavity sensor tracks an approximated condition calculated from the change in parameter measurements measured by the at least one external sensor over time. In an embodiment, results of the approximated parameter tracking can be used in conjunction with an optimal pre-defined pressure-time curve.

A molding machine management device that is able to couple to a molding machine includes a storage unit configured to store, in chronological order, numerical value information on a molding process when a molded product is molded by the molding machine and four-factor information on four factors of production which includes a man, a machine, a material, and a method when the molded product is produced, and an output control unit configured to classify the numerical value information into a plurality of groups for periods divided according to time when the four factors of production changes, and output the numerical value information classified into the plurality of groups to an output unit in group units.
