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： In an injection device according to an embodiment, each of a plurality of outer peripheral protrusions of a screw is formed with an outer peripheral protrusion inclined surface, and each of a plurality of inner peripheral protrusions of a through-hole of a bush is formed with an inner peripheral protrusion inclined surface. The injection device advances the bush until a linear-motion torque exceeds a linear-motion torque threshold, and, if a rotation torque exceeds a rotation torque threshold before the linear-motion torque exceeds the linear-motion torque threshold, ends control processing when the linear-motion torque exceeds the linear-motion torque threshold.

摘要： An injection molding apparatus and method of fabricating a molded part are provided. The apparatus may include a barrel, a nozzle enclosing an end of the barrel and defining an opening in fluid communication with an inside of the barrel, and an extrusion screw positioned at least partially inside the barrel and rotatable relative to the barrel. The extrusion screw may include a screw tip. Relative axial movement between the barrel and the extrusion screw may open or close the opening of the nozzle to permit or prevent, respectively, material flow through the opening of the nozzle. The method may include clamping a mold, opening a nozzle, rotating the extrusion screw to pump a molten material into the mold until the mold is filled, closing the nozzle, and unclamping the mold to release a molded part.

摘要： The application relates to a plasticizing unit with a cylinder and a screw that is rotatably mounted in the cylinder and has a screw section which is designed as a shearing section and in which a blocking web encircling the screw core in a helical manner and a main screw thread enclosed by the blocking web are provided. A shearing web runs in the main screw thread parallel to the blocking web at a lower height than the blocking web. In this manner, two screw threads are produced which run parallel to each other and are separated by the shearing web. The threads are designed in the form of wave screw threads. Each wave screw thread is equipped with one or more wave peaks with a surface which is designed in the form of a plateau and forms a wave peak shearing surface, wherein the wave peak shearing surface is located at the same height as the surface of the shearing web in the region. The shearing web surface section which lies in the region of a wave peak shearing surface constitutes a shearing web sharing surface. A wave peak shearing surface and a shearing web shearing surface together form a total shearing surface. A specified total shearing surface together with the inner wall of the cylinder forms a shearing gap in accordance with a shearing gap size specified for the total shearing surface.

摘要： An injection molding machine includes a screw inserted in an injection cylinder and configured to be movable in an axial direction of the screw, a motor configured to move the screw, a torque detection unit configured to detect a torque of the motor, a position detection unit configured to detect a position of the screw, a motor drive control unit configured to drive the motor to thereby advance the screw to a foremost position in a direction of injection, a processor, and a memory. The processor and memory are configured to determine that unmelted resin remains inside the injection cylinder if the torque of the motor becomes equal to or greater than a limit torque while the screw is advancing to the foremost position.
