Patent number: 11897176Abstract: An injection molding machine having vent mechanism includes a plastication device, an injection device, a junction, a vent-up sensor, and a controller. The vent-up sensor detects vent-up. When the vent-up is detected, the controller switches from normal conditions to vent-up suppression conditions. The vent-up suppression conditions have at least one of the followings: increasing a rotational speed of the plastication screw to be higher than that in the normal conditions; using retreat-metering when the retreat-metering is not performed in the normal conditions, wherein in the retreat-metering, in addition to a pressure of the resin material, a force in a retreat direction is applied to the injection plunger to move the injection plunger at a predetermined retreat speed in the metering; and increasing the retreat speed of the injection plunger to be higher than that in the normal conditions when the retreat-metering is performed in the normal conditions.Type: GrantFiled: February 4, 2021Date of Patent: February 13, 2024Assignee: Sodick Co., Ltd.Inventors: Shuji Aiba, Hiroya Mukaide, Kenzo Akiyama

Patent number: 11890788Abstract: Methods of producing polymer-metal hybrid components that are bonded by C—O-M bonds at the interface using at least one of the hot pressing, rolling, and injection molding methods to create chemical bond formation conditions at the polymer and metal interface. When the thermal cycle and compressive pressure specified herein is combinationally created at the polymer and metal interfaced, strong C—O-M bonds forms at the interface and strongly bonds the metal and polymer together through the reaction carbonyl groups (C?O) in polymer and the metal surface. For polymers lacking enough carbonyl groups, new functional groups can be in-situ generation through introducing distributed air pockets at the polymer-metal interface for forming 3-dimensional distributed C—O-M bonds at the interface.Type: GrantFiled: May 18, 2021Date of Patent: February 6, 2024Assignee: THE REGENTS OF THE UNIVERSITY OF MICHIGANInventors: Fengchao Liu, Pingsha Dong

Patent number: 11872771Abstract: Non-standard, resin-infused fiber bundle includes localized regions of fibers having a sub-nominal amount of polymer resin positioned along its length. These regions function as “bending regions,” where the non-standard resin-infused fiber bundle can be readily deformed by virtue of the reduced amount of resin. The bending regions segregate the non-standard resin-infused fiber bundle into what is, effectively, discrete (smaller) segments of (standard) resin-infused fiber bundle. The ability to easily manipulate the non-standard, resin-infused fiber bundle via the bending regions is useful for creating fiber-bundle-based preforms, and preform charges (assemblages of fiber-bundle-based preforms).Type: GrantFiled: September 21, 2020Date of Patent: January 16, 2024Assignee: ARRIS COMPOSITES INC.Inventors: Todd Pelman, Dylan Harper, Christopher Bender, Riley Reese, J.
