  • Publication number: 20230191538
    Abstract: A laser processing device is a device that processes a workpiece using a laser beam, and includes a cutting pallet and a container. The cutting pallet includes a placement unit that supports a lower surface of the workpiece. The container supports the cutting pallet and is capable of storing a transmission inhibition liquid inhibiting transmission of light having a wavelength greater than or equal to 0.7 µm and less than or equal to 10 µm up to a height position of the placement unit.

  • Patent number: 8460586
    Abstract: An injection molding device is provided with a mold, an injection unit equipped with an injection screw that is displaceably configured such that a molten resin is filled into a cavity by forward movement to perform plural injection operations including at least a filling operation and a pressure keeping operation by displacing the injection screw, a position sensor for detecting the position of the injection screw, a temperature sensor capable of measuring the temperature of the vicinity of the cavity of the mold, a temperature adjustment unit capable of adjusting the temperature of the mold by heating or cooling the mold, a control unit for controlling the displacement of the injection screw and the temperature of the mold and determining plural switching timings of the injection operations on the basis of the position of the screw, and a display unit for displaying an image.

  • Patent number: 8043537
    Abstract: There are provided an injection molding system, a computer program, a method of injection molding, and an injection molding machine capable of performing precise temperature control of a mold even when there is a delay in temperature increase of the mold in heat supply with a heating medium. The temperature control is performed so that temperatures of a fixed mold and a movable mold are maintained between an upper limit TU and a lower limit TL of a predetermined temperature range after start of injection of resin during an injection molding cycle. The temperature control of the fixed mold and the movable mold is performed only by switching ON/OFF supply of the heating medium, and cooling with a cooling medium is not performed.
