Systems and methods are provided for enhancement of vacuum bagging processes for a composite part. One system includes dispensers configured to dispense materials onto a forming tool for a composite part, and a controller. The controller is able to identify a selected location for placing the composite part on the tool, to direct the dispensers to apply a mold release agent onto the tool based on the selected location, to apply a sealant onto the tool proximate to the selected location, to lay up a ply of constituent material for the composite part atop the mold release agent at the selected location, to apply a pressure pad material atop the constituent material, to apply a breather material atop the pressure pad, and to apply vacuum bag material atop the ply proximate to the selected location to cover the ply as well as the sealant.

A resin molding apparatus provided with a first mold and a second mold for pressing a flat thermoplastic resin sheet into a molded article, wherein the molded article has a shape provided with a flat plate part and a concave-convex part continuous with the flat plate part, and a heating part is provided to locally heat a concave-convex molding region corresponding to the concave-convex part in the thermoplastic resin sheet when the thermoplastic resin sheet is pressed.

A method and device for manufacturing the tire are provided. For each tire obtained by feeding green tires having an identical specification into an identical vulcanizer, using an arrangement mechanism, with circumferential positions of the green tires varied with respect to the vulcanizer and vulcanizing the green tires, a storage unit stores characteristic value data of at least one of a UF or DB value and feed position data identifying the circumferential position of the green tires, a calculation unit calculates, based on the stored data, the circumferential position of the green tires with respect to the vulcanizer at which a characteristic value related to the characteristic value data is brought within a tolerance range, and feeding using the arrangement mechanism, into the vulcanizer, the green tire to be newly vulcanized while adjusting the green tire to the circumferential position with respect to the vulcanizer being calculated.

Disclosed herein is a die for forming a part. The die comprises a base, comprising a heat-platen interface surface and a part interface surface, and wherein the heat-platen interface surface and the part interface surface are separated by a thickness of the base. The die also comprises inserts, embedded within and circumferentially closed by the base, spaced apart from each other, and extending in a first direction from the heat-platen interface surface toward the part interface surface. The base is made of a first material having a first thermal conductivity. The inserts are made of a second material having a second thermal conductivity. The first thermal conductivity is different than the second thermal conductivity.

Layers of composite material, such as pre-peg, may be deposited on a reconfigurable polymer mold. An array of actuated pins may deform the polymer mold into a desired 3D shape. The composite material may be inside a cavity formed by the mold and a flexible bag. A vacuum pump may remove air from the cavity, creating a partial vacuum. The partial vacuum may cause the flexible bag to press the composite tightly against the mold, so that the composite conforms to the desired 3D shape. One or more heating elements may be embedded in the mold and may heat the composite to cure the composite. Ball joints may connect the actuated pins to the polymer mold.
