Abstract: A transfer molding method includes supplying melted resin to a first metallic mold, conveying the first metallic mold onto which the resin was supplied to a position opposing a second metallic mold, performing transfer molding by sandwiching the resin between the two metallic molds, and cooling the resin after performing transfer molding. The performing transfer molding includes discharging residual air that remains in a recess via a groove portion.

Abstract: A method and a machine account for changes in material properties of molten plastic material during an injection run. A change in a control signal is calculated by a controller during the injection molding run. If the change in the control signal indicates a change in material flowability, the controller alters a target injection pressure to ensure that molten plastic material completely fills and packs a mold cavity to prevent part flaws such as short shots or flashing.

Abstract: A hot-runner mold gate structure includes a body having a path, and a room is defined in one end of the path. A guide member is inserted in a bushing, and both of which are located in the room. A locking member is connected to the room and has a reception area in one end of the locking member. The guide member has an axial guide slot and a guide hole. The guide member has a tip which protrudes through an outlet in the distal end of the bushing. Melted PET passes through the guide hole, the guide slot and the gap between the tip and the inside of the outlet to enter into the mold set. The contact area between the locking member and the bushing is minimized to maintain a certain temperature at the outlet of the bushing to avoid the PET from being cooled.

Abstract: Types of molded articles carried by a carrier are identified and the molded articles are sorted based on image-related information for the molded articles molded based on set operating conditions for injection molding machines and molded article images acquired by an image acquisition unit. It is thus possible to narrow down candidate images in processing in a molded article identification unit, thereby making it possible to construct an injection molding system that has excellent production efficiency with a reduced load on processing in the molded article identification unit.
