An injection molding system includes a sensor that detects a state of a purged molding material, and a purged material analysis unit that obtains a detection signal of the sensor and analyzes the purged molding material. Whether or not the purge operation is completed is determined based on the detection signal of the sensor so as to complete the purge operation. The purge operation is thus allowed to be completed with a minimum purge amount.

To provide a quality prediction system predicting a quality element of a molded item using machine learning. The quality prediction system includes a sensor disposed in the mold and configured to detect state data regarding the molten material supplied in the cavity, a learned-model storage unit configured to store a model which is a learned model generated by machine learning in which the state data detected by at least the sensor is used as a training data set and is a learned model related to the state data and a quality element of the molded item, and a quality prediction unit configured to predict the quality element of the molded item which is newly molded based on the state data newly detected by the sensor and the learned model.

A sensing module includes a hollow body, a first photo sensor, and a second photo sensor. The hollow body includes a cavity portion and an insertion portion connected to each other. The insertion portion has a first channel and a second channel. The first photo sensor is disposed in the cavity portion of the hollow body and corresponds to the first channel to sense an ambient temperature and a test object temperature. The second photo sensor is disposed in the cavity portion of the hollow body and corresponds to the second channel to sense the ambient temperature.

The present application relates to an injection molding system, comprising: an input condition storage section 23 to store an input plasticization condition; an ideal plasticization state storage section 24 to store information of an ideal state of plasticization; an input condition simulation section 29 for the plasticization condition based on data stored in the input condition storage section 23; a comparison section 25 to compare the information stored in the ideal plasticization state storage section 24; an optimal condition analysis and calculation section 26 to calculate the optimal plasticization condition when the data stored in the input condition storage section 23 is decided not to be the ideal state of plasticization by the comparison section 25 using the data of the input condition storage section 23 and the information stored in the ideal plasticization state storage section 24; and a condition change indicating section 28 to display information necessary to make a change to the optimal plasticization condition on a display section 22 based on a result of calculation by the optimal condition determination section 26.

A remote controller can be provided on any apparatus that employs feedback control from a native controller to add functionality to the apparatus where the native controller is not capable of providing such functionality independently.

A method of forming a urinary catheter is disclosed that includes injecting a polymer melt through a primary melt channel and into an elongated recess around an outer surface of a core; and controlling a first pressure of the polymer melt in a first secondary melt channel separately and individually from a second pressure of the polymer melt in a second secondary melt channel and reducing stress of the polymer melt along the elongated recess. Opening the mould and removing the core provides a moulded intermittent urinary catheter having an open distal end and a closed proximal tip.

A protective cover for a plasticizing cylinder of a shaping machine has an elongate internal space which is enclosed by at least one wall and in which the plasticizing cylinder can be arranged. A terminal box for heating strips arranged on the plasticizing cylinder projects into the elongate internal space, and the at least one wall has an opening which is closed by an openable cover member. In an opened condition of the openable cover member, the opening allows access to the terminal box or the interior of the terminal box.

A method for the variothermal temperature control of an injection mould using a temperature control device, the method including at least the following steps: in a learning phase, determining a temperature control characteristic of the temperature-controllable system including at least the injection mould and the temperature control device, in order to obtain individual reference values for the system, with which the temperature control device can be controlled in order to obtain a nominal temperature profile; and in a production phase: temperature control of the injection mould with the reference values determined during the learning phase; determining deviations of an actual temperature profile of the injection mould in relation to the nominal temperature profile during the production cycle and calculating corrected reference values from these deviations; and carrying out a resulting production process using the corrected reference values.

A foaming process and a method for operation of the foaming process are provided. The method includes flowing a molten polymeric material into a mold from an upstream device, receiving the molten polymeric material in a cavity of the mold, and maintaining a repeatable, uniform pressure profile as the molten polymeric material is delivered into the mold.

A casting tool, for example a core shooting tool or a permanent mould, having an upper tool part and a lower tool part, which on opposite sides each have at least one engraving formed as a shell engraving and which form a mould cavity, characterized in that the shell engraving on an outer side facing away from the mould cavity comprises at least one physical sensor which is configured to measure a physical quantity with respect to a material accommodated in the mould cavity. Furthermore, a corresponding casting method is described.
