Abstract: A hydraulic drive apparatus includes a first hydraulic pump, a drive motor connected to the first hydraulic pump, a hydraulic line system connecting the first hydraulic pump to the consumer, and a closed-loop control unit. The closed-loop control unit has a first switching element to change a displacement volume of the first hydraulic pump between a predetermined minimum value and a maximum value. A second hydraulic pump is connected to the drive motor, and the hydraulic line system connects the second hydraulic pump to a consumer and has a first branch line connected to the first hydraulic pump, a second branch line connected to a second hydraulic pump, and a main line. The two branch lines open into the main line, and the closed-loop control unit has a second switching element for changing a displacement volume of the second hydraulic pump between a predetermined minimum value and a maximum value.

Abstract: A method for monitoring a molding process carried out in cycles includes determining at least two nearest neighbors in the form of cycle data from at least two past cycles, such that the cycle data of the at least two nearest neighbors lie nearer to the current cycle data than the cycle data which do not pertain to the at least two nearest neighbors. Only those past cycles for which quality data are contained in the data collection are used for the determination of the at least two nearest neighbors. A predictability criterion is checked to determine whether a quality variation of the quality data of the cycles of the at least two nearest neighbors is smaller than a maximum variation and/or larger than a minimum variation. If the predictability criterion is not met, a first notification that a quality and/or a quality datum of the molded part is not reliably predictable is issued.

Abstract: A method for determining positions of a real moulding material front during a process to be carried out with a moulding machine, wherein
a simulation progression (SV) of a variable characteristic of the processa is calculated,
positions of a simulated moulding material front are determined from the simulation,
the real process is carried out, and at least one measurement progression (MV) of the at least one characteristic variable is measured directly or indirectly,
a transformation is chosen, which has at least one parameter (ΔV, kp, Vunknown),
the transformation is applied to the at least one simulation progression (SV), with the result that a transformed simulation progression (tSV) is formed, and
a parameter value is determined for the parameter (ΔV, kp, Vunknown) such that a deviation between the measurement progression (MV) and the transformed simulation progression (tSV) is minimized according to a predetermined error measure or according to an operator input.-

Abstract: A plasticizing unit and/or injection unit for a molding machine with an injection cylinder for plasticized material, at least one degassing opening, and a degassing device in flow connection with the at least one degassing opening for releasing and discharging undesired gases from the plasticized material. The degassing device has a flow element, in flow connection with the at least one degassing opening, which is formed to generate a negative pressure by the Venturi effect at the degassing opening, and/or the degassing device has a filter device, in flow connection with the at least one degassing opening, for filtering gases being released.

Abstract: A method of determining a target value of a state variable includes preparing a mixture of the molding material and the gas with different test values of the state variable, and the mixture is respectively compressed or decompressed. In the compression or decompression step, the state variable of the mixture and/or a further state variable of the mixture is measured directly or indirectly, and determination values of a compression behavior variable characteristic of the compression behavior of the mixture are determined from the measurement values. A criterion directed to a solution state of the gas is checked, and a lowest or highest value of the state variable is deduced at which the gas is in solution in the molding material. The lowest or highest value of the state variable at which the gas is in solution in the molding material is used as the target value.

Abstract: Method for improving a cycle time of a molding system operating in cycles, wherein the molding system is set up to produce molded parts in cycles, wherein the cycles include partial phases, for at least one partial phase or at least one group of partial phases a partial phase duration is measured or ascertained with reference to settings of the molding system, an optimum partial phase duration is calculated for the at least one partial phase or the at least one group of partial phases on the basis of a machine configuration, if the measured or ascertained partial phase duration deviates from the optimum partial phase duration by more than a predefined amount, an indication that the setting of the molding system is improvable with respect to the at least one partial phase or the at least one group of partial phases is issued.

Abstract: A method of diagnosing a state of at least one component of a molding machine is performed such that a state of the at least one component is determined on the basis of a vibration measured at the molding machine. A drive unit of the molding machine accelerates and/or decelerates at least one movable element provided at the molding machine in such a way that the vibration is stimulated in a predetermined frequency range.

Abstract: A target value progression for a process parameter functioning as a setting variable is established so that an actual value progression for a selected variable has a desired property, or the desired actual value progression itself ensues. The actual value progression occurring in relation to the first configuration is predetermined as a reference value progression for the selected variable, and a target value progression for the process parameter functioning as the setting variable is established by a computer so that the reference value progression as the actual value progression with the desired property or the desired actual value progression itself ensues when the shaping machine in the second configuration operates in a production cycle in accordance with the selected target value progression for the at least one process parameter functioning as the setting variable.
