摘要： 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.

摘要： A controller is for an injection molding machine including an injecting member configured to push a molding material in a forward direction, the molding material containing a bioplastic; and an injection drive source configured to cause the injecting member to travel forward or backward. The controller is configured to perform filling in which a forward travel speed of the injecting member is controlled so that an actual value of a pressure applied from the injecting member to the molding material does not exceed an upper limit of the pressure. In at least a part of the filling, a value of from 550 mm/s through 700 mm/s is settable as a set value of the forward travel speed of the injecting member, and a value of 200 MPa or higher is settable as the upper limit of the pressure.

摘要： An injection molding machine having vent mechanism includes a plastication device, an injection device, a junction, a vent-up sensor, and a controller. The vent-up sensor detects vent-up. When the vent-up is detected, the controller switches from normal conditions to vent-up suppression conditions. The vent-up suppression conditions have at least one of the followings: increasing a rotational speed of the plastication screw to be higher than that in the normal conditions; using retreat-metering when the retreat-metering is not performed in the normal conditions, wherein in the retreat-metering, in addition to a pressure of the resin material, a force in a retreat direction is applied to the injection plunger to move the injection plunger at a predetermined retreat speed in the metering; and increasing the retreat speed of the injection plunger to be higher than that in the normal conditions when the retreat-metering is performed in the normal conditions.

摘要： A system and method for determining the position of a flow of melt within an injection molding system comprises a switch and a pin that actuates the switch. The pin has a first end positioned closer to the anticipated flow path of the melt and a second end that is positioned to be in contact with the switch, such that when melt enters the anticipated flow path, the pin is pushed to activate the switch.
