Abstract: A method of monitoring and controlling a molding clamping apparatus in an injection molding or other molding process is disclosed. The method includes creating a target strain profile, receiving a deviation limit, receiving a change in strain relating to a mold while it is closing from a first strain gauge, identifying a deviation from a target strain profile based on the output from the first strain gauge, determining that the deviation exceeds the deviation limit, and adjusting the rate or force of clamp movement. The target strain profile may have a first portion relating to a clamp closing process, a second portion relating to a filling process, and a third portion relating to a clamp opening process. The first portion relating to the clamp closing process may include an intermediate portion relating to a coining process having an intermediate clamp force setpoint.

Abstract: A plastic injection-moulding machine includes an injection unit for processing a plastic mass, and a closing unit having an injection-moulding tool with a cavity, into which plastic mass is injected by the injection unit to produce a moulded part. A machine controller controls the injection unit and the closing unit according to a machine program running on the machine controller. A user interface device communicates with the machine controller and has a screen for displaying text information and/or image information. The machine controller includes a data memory for storing the text information and/or image information in the form of data sets, and a process generator for manually assigning each state parameter of the plastic injection-moulding machine a data set. The process generator automatically writes the data set into the data memory or automatically reads out the data set for display on the screen in accordance with the associated state parameter.

Abstract: 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).

Abstract: A specific mold status Ac is caused in advance in which the interval of an inner portion Xi in the parting plane direction of a parting gap C between a fixed mold 2c and a movable mold 2m during the injection filling is larger than the interval of an outer edge portion Xo and the interval of the outer edge portion Xo is equal to or lower than a predetermined size Ls including 0. A molding injection pressure Pi is set as an injection pressure at which a non-defective product can be molded and a molding mold clamping force Pc is set as a mold clamping force by which a non-defective product can be molded. During the production, a mold 2 is clamped by a molding mold clamping force Pc and the clamped mold 2 is filled with the injected resin R by a molding injection pressure Pi. After a predetermined cooling time Tc has passed, a molded piece G is removed.

Abstract: A method is described for operating an injection moulding machine, which has one or more movable machine parts which can be moved by suitable drives along specifiable travelling distances. Movement of a movable machine part is repeated cyclically. In order to reduce the movement times of the movable machine parts to a minimum, provision is made for one or more of the movable machine parts to successively reduce the power reserves of one or more of the drives associated with a movable machine part, until a specifiable minimum of power reserve is reached, wherein the minimum can be zero. In each cycle, the power reserve of the drive or drives is determined and is successively reduced, in particular from cycle to cycle. A movable platen, an ejector, a core puller, a plasticizing screw and/or an injection piston can be provided as movable machine part.

Abstract: An injection molding method of a resin molded article closes a first die and a second die by a predetermined clamping force, conducts pressure holding and cooling after filling a cavity formed between the first die and the second die with a molten resin, and opens the first die and the second die. The injection molding method conducts clamping, filling, pressure holding, and cooling for the first die and the second die by a clamping force previously specified on the basis of a sample with which pressure in the cavity during a cooling process indicates a minimum and which is specified from samples of clamping forces.
