    摘要: A device for forming or molding elements on surfaces of a semi-finished product includes a C-shaped bracket element for displacing using a manipulator to a defined position with respect to a semi-finished product. An arrangement implemented for injection molding is disposed on a first leg and a backing holder is disposed on the second leg of the C-shaped bracket element. A semi-finished product can be disposed between the backing holder and the arrangement. A first molding tool is disposed in the direction toward a surface of the semi-finished product. The arrangement and/or the backing holder is/are displaceable against the corresponding surface of the semi-finished product, such that the open side of the first molding tool applies pressure to the corresponding surface of the semi-finished product and the backing holder contacts and applies pressure to the opposite surface of the semi-finished product.

    摘要: The method for manufacturing a foamed product uses a manufacturing apparatus having a plasticizing cylinder in which an introduction port for introducing a physical blowing agent into a starvation zone is formed, and an introduction speed adjustment container connected to the introduction port, wherein the manufacturing method comprises: turning a thermoplastic resin into a molten resin; introducing the physical blowing agent at a predetermined pressure into the starvation zone through the introduction speed adjustment container and maintaining the starvation zone at a predetermined pressure; setting the molten resin to a starved state; bringing the molten resin in the starved state and the pressurized fluid into contact with each other; and molding the molten resin into a foamed product. The maximum value of the inner diameter of the introduction speed adjustment container is larger than the inner diameter of the introduction port.

    摘要: An injection molding apparatus includes an electric motor, a torque variable mechanism that changes an output torque of the electric motor, and a screw driving unit that transmits the output torque of the torque variable mechanism to a feed screw, whereby the feed screw is turned by the electric motor, the torque variable mechanism and the screw driving unit. The torque variable mechanism applies, to the feed screw, a torque equivalent to a hydraulic drive. The electric motor is interchangeable with a hydraulic motor to enable the injection molding apparatus to change between electric and hydraulic drive of the feed screw.
