A method for determining an actual volume Vr of an injection-moldable compound during an injection-molding process is disclosed. The injection-moldable compound is introduced into at least one cavity of the mould. The method includes the steps of: a) determining a theoretical volume Vt from process variables at least during a filling phase of the injection-molding process, b) determining and/or measuring at least one value for at least one compound pressure pM, c) selecting a material-specific compression k (p), corresponding to the value of pM, of the injection-moldable compound, and d) calculating an actual volume Vr by taking into account the compression k (p).

A method of detecting and compensating for a non-operational mold cavity in an injection molding apparatus having a plurality of mold cavities and an injection molding screw or ram includes injecting, via the injection molding screw or ram, a molten thermoplastic material into the plurality of mold cavities. The method includes measuring a first process parameter of the injection molding apparatus at a pre-determined time during or after the injecting.

Then, when it is determined that one or more mold cavities are non-operational, the method includes automatically adjusting the first process parameter or a second process parameter of the injection molding apparatus.

A controller is for an injection molding machine including an injecting member configured to push a molding material in a forward direction, the molding material containing a bioplastic; and an injection drive source configured to cause the injecting member to travel forward or backward. The controller is configured to perform filling in which a forward travel speed of the injecting member is controlled so that an actual value of a pressure applied from the injecting member to the molding material does not exceed an upper limit of the pressure. In at least a part of the filling, a value of from 550 mm/s through 700 mm/s is settable as a set value of the forward travel speed of the injecting member, and a value of 200 MPa or higher is settable as the upper limit of the pressure.
