A resin detection system for closing an automated valve to prevent resin entering a vacuum line portion of an outlet line is described. The resin detection system comprises a support (300) to a pneumatically-actuated device (320), a capacitive sensor (380) and a valve (410) are mounted. The sensor is configured to provide at least one signal indicative of the presence of resin in the outlet line which is used to close the valve automatically once the presence of resin is sensed by the capacitive sensor. The resin detection system forms part of an injection moulding apparatus and receives signals from a processor thereof to ensure that, if too much resin is injected, the valve is automatically closed even in the event that the sensor does not detect the presence of resin in the outlet line.

An example method for making a radio frequency identification (RFID) tag according to the present disclosure includes holding a transponder within a cavity of a mold using a fixture, closing the mold, injecting material into the mold cavity and around the transponder to form a part of the RFID tag, opening the mold, and ejecting the part from the mold.

According to one embodiment, a mold includes a substrate clamping surface, a cavity, a suction part, a vent, an intermediate cavity, and an opening/closing part. The substrate clamping surface contacts a surface of a processing substrate. The cavity is recessed from the substrate clamping surface. The suction part is recessed from the substrate clamping surface. The vent is provided on a path between the cavity and the suction part, communicates with the cavity, is recessed from the substrate clamping surface to a vent depth. The intermediate cavity is provided between the vent and the suction part on the path, communicates with the vent, and is recessed from the substrate clamping surface to an intermediate cavity depth deeper than the vent depth. The opening/closing part opens and closes the path and is provided between the intermediate cavity and the suction part on the path.

An inspection method for an injection molding device includes: a first step of acquiring a first detection value from a sensor using a test mold having the sensor, the sensor measuring a temperature or pressure of a molten material injected from a first injection molding device into a cavity section demarcated by a fixed mold and a moving mold; a second step of injecting a molten material from a second injection molding device into the cavity section and acquiring a second detection value from the sensor; and a third step of performing an inspection using the first detection value and the second detection value.

To provide an injection molding machine which includes: a melting unit including a screw rotating about a rotation axis and having a groove forming surface on which a groove is formed and a barrel provided with a communication hole in a facing surface facing the groove forming surface, and configured to plasticize a material to generate a plasticized material and make the plasticized material flow out of the communication hole; a heating unit configured to heat the melting unit; an injection nozzle in communication with the communication hole and configured to inject the plasticized material into a mold; an injection control unit including a cylinder coupled to the communication hole and a plunger; a pressure detection unit configured to detect a pressure of the plasticized material flowing into the communication hole; and a control unit. The control unit controls the injection control unit to execute, based on a detected value, at least one of a metering operation of metering the plasticized material in the communication hole in the cylinder, and an injecting operation of injecting the plasticized material in the cylinder into the mold via the injection nozzle.

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 measuring arrangement for a shaping machine includes a measuring diaphragm deformable by a force action, a measuring device for metrological detection of a deformation of the measuring diaphragm with the output of a measurement signal, and an evaluation device connected to the measuring device. The evaluation device, in the course of a first calibration, can convert the measurement signal originating from the deformation of the measuring diaphragm with a force from a first force value range into a first output signal, and the first output signal is in a previously defined value range. The evaluation device, in the course of a second calibration, can convert the measurement signal originating from the deformation of the measuring diaphragm with a force from a second force value range differing from the first force value range into a second output signal, and the second output signal is in the previously defined value range.

A method and system for co-injection molding of two molten plastic materials that allows monitoring and utilization of injection pressure and optionally melt pressure and/or flow front pressure during an injection run. A controller alters the injection pressure so as to achieve and maintain optimal or desired ratios of injection pressure, and optionally melt pressure and/or flow front pressure, of the two molten plastic materials. This allows for more precise part manufacture, including reducing the thickness of a skin or shell layer compared to a core layer of a molded part.

A melt temperature sensing kit includes a housing and a cup. The housing defines a cavity and has an outer periphery configured to be received by a platen of an injection molding machine. The cup has a proximate end and a distal end and is configured to be received within at least a portion of the cavity. The cup includes a base enclosing the distal end of the cup and a sidewall extending from the base, the sidewall defining a first aperture at the proximate end of the cup, a second aperture disposed between the proximate end and the distal end of the cup, and an internal volume. The first aperture, the second aperture, and the internal volume cooperate to define a flow path. At least one of the housing and the cup facilitate measurement of a shot flow temperature as part of a melt temperature measurement process.

An additive feeder system is presented which is operable for use in a plastic injection molding machine including an injection component and a clamping component. The additive feeder system includes a feeder control unit, a feeder supply mechanism and feeder dosage control mechanism. The additive feeder system is operable to provide a specific dosage of the additive materiel in real-time for mixing with the raw material to achieve desired product characteristics. The additive feeder system may be applied to injection molding and extrusion, such as molding processes, plastic molding processes, blow molding, compression molding, extrusion molding, injection molding and laminating, and comprising additive feeders, for example for color mixing and nutrient supplements.
