A misalignment sensing system for a molding structure and a method for using same. The molding structure includes a first component and a second component, at least one of the components being selectively repositionable between a closed configuration of the mold structure and an open configuration of the mold structure. The misalignment sensing system includes an alignment member including a male portion coupled to and extending from the first component of the molding structure, and a female portion defined in the second component of the molding structure, the female portion being configured to receive the male portion when the molding structure is in a closed configuration; and at least one sensor connected to one of the male and female portions and being configured to detect a deformation of any one of the male portion and the female portion, the deformation being induced by a misalignment of the molding structure.

A shrinkage detection device for a polymer injection molding apparatus detects a shrinkage experienced by an injection molded element for assessing a quality of the molded element. Shrinkage, along with temperature and pressure of the melt within the mold during cooling, indicates a sufficiency of the resulting molded element for intended purposes. Sufficiency includes parameters such as flexibility, shear strength and longevity, and is accurately performed can replace conventional sample testing of molded articles that are expensive and time consuming.

An injection device for an injection moulding machine includes an injection drive, which is designed so as to rotate an injection spindle relative to a spindle nut, and injection slide, which is connected to the spindle nut in a rotationally rigid manner on a lateral surface and held so as to be movable along a slide guide, a guide housing, on which a plasticizing cylinder is held, a bearing housing, in which a driveshaft is rotatably supported and which is connected to the injection slide, as well as a metering drive, which is fastened on the injection slide and designed so as to rotate the driveshaft. A force measuring device is externally fastened on a force transmission component that is arranged between the bearing housing and the spindle nut and lies in the flux of force of the injection device.

A shaping machine or a handling apparatus for a shaping machine includes at least one measuring device for measuring the spacing of two selected points of the shaping machine or the handling apparatus. Furthermore, the at least one measuring device has at least one piezoresistive micromechanical sensor.

A wireless sensor system is described which can be used to measure temperature and/or pressure within an electromagnetically shielded environment. The sensor system includes an embedded processor which intermittently transmits data from the sensors. In electromagnetically shielded environments, the processor transmits the data when the electromagnetically shielding components are moved into a non-shielding configuration.
