    摘要： Provided is an injection molding machine including an injection unit including a cylinder that heats a molding material, and a screw rotatably disposed within the cylinder; and a monitoring unit that monitors the temperature of the injection unit. The screw includes a rotating shaft; a first spiral flight that protrudes from an outer periphery of the rotating shaft, and a second spiral flight that partitions a groove formed by the first flight. The height of the second flight is lower than the height of the first flight. The monitoring unit monitors the temperature of the second flight and/or its vicinity during the rotation of the screw, and determines the molten state of the molding material on the basis of monitoring results.

    摘要： Controlling viscosity of molten polymers, such as polycarbonate, prior to a molding operation such as injection molding, extrusion, thermoforming or blow molding, involves a reduction of viscosity in the plastic melt at constant temperature, by the action of a vigorous mechanical extensional shear vibration, with minimum or no external pressure, at a constant amplitude and frequency, causing the melt to become highly elastic and simultaneously fatigued for a certain time at that temperature, maintaining this high elastic state until the macromolecules have partially or totally disentangled, in a controllable manner, at which stage the melt is ready for a molding operation such as a simple quenching operation or an extrusion process followed by quenching to produce pellets or compounds with a better mix or a lower viscosity when remelted, or an injection molding operation where the melt viscosity has been greatly reduced allowing a better processability of the injected part.

    摘要： A process of forming molded articles using an injection molding apparatus is provided. The process includes providing a thermoplastic material to the injection molding apparatus. The thermoplastic material is heated such that the thermoplastic material is in a molten state. The molten thermoplastic material is injected into at least one mold cavity of the injection molding apparatus using an injection element. A melt pressure of the thermoplastic material filling the at least one mold cavity is monitored using a sensor. The sensor provides a signal indicative of melt pressure in the cavity to a controller. The controller controls the injection element thereby changing melt pressure of the thermoplastic material filling the at least one mold cavity based on the signal to reach a target cavity pressure. A molded article is formed by reducing a mold temperature of the thermoplastic material within the at least one mold cavity.
