Patent number: 7725211Abstract: A control system for injection molding machines comprises a memory means (16) for storing set values. Further, a signal input for the transmission of actual values to the control system is provided. A first control means (18) is used for the transmission of a control field with consideration to previous values. A second control means (20) is provided for the transmission of a correction value, in particular with consideration to a deviation of the actual value from the set value. A correlation means (22) serves to correlate the control field values with the correction value for outputting a control variable.Type: GrantFiled: January 16, 2007Date of Patent: May 25, 2010Assignee: Dr. Boy GmbH & Co. KGInventor: Franz Josef Ludwig
