A mold assembly for forming a component exhibiting a sealed interior, including providing first and second mold halves, forming first and second half shells of material within cavities defined within each of the mold halves, and upon mating the mold halves together in a first closed mold configuration. The mold halves are reopened, with at least one of the shells being subsequently reoriented such that the first and second half shells are arrayed in opposing fashion with perimeter extending edges of each half shell arranged in contact with one another. Additional steps include reclosing the mold halves and subsequently forming a second perimeter extending material in contact with the contacting perimeter extending edges in order to bond the half shells together, upon which the mold halves are reopened and a completed component removed.

An injection molding apparatus for producing a plastics molding comprising a first component, a second component, and a third component comprises a first mold plate having at least 3 first mold nests, and a second mold plate having at least 3 second mold nests. In the closed state, the mold plates cooperate in the production of the plastics mold. In the opened state, the second mold plate is rotatable relative to the first mold plate. The at least 3 second mold nests comprise, in a case A), at least two second mold nests for injection molding the first component, and at least one second mold nest for injection molding the third component, or, in a case B), at least two second mold nests for injection molding the second component, and at least one second mold nest for injection molding the first component.

An injection molding apparatus includes a fixed die having a first gate opening and a second gate opening formed therein, a movable die configured to be clampable to the fixed die, a first injection unit that injects a first molding material into a cavity defined by the fixed die and the movable die via the first gate opening, and a second injection unit that injects a second molding material into the cavity via the second gate opening.

An assembling apparatus that has a mold in which a second unit opposes a first unit and that is configured to assemble an assembled product from a plurality of parts. The first unit includes first, second, and third movable portions, which comprise, respectively, a plurality of first forming portions, a plurality of second forming portions, and a plurality of third forming. The second unit comprises a fourth movable portion, a fourth forming portion, a fifth forming portion, a sixth forming portion, and a plurality of assembling portions. The fourth movable portion is configured to move so as to switch at least one assembling portion opposed to at least one first forming portion, at least one other assembling portion opposed to the at least one second forming portion, and at least one remaining assembling portion opposed to at least one third forming portion.

An injection mold for producing a double walled drinking vessel includes first and second mold portions. The first mold portion forms a first and second cavities corresponding to the outer shape of the outer container and the outer shape of the inner container, respectively. The first and second cavities are located concentrically with respect to a central axis. An index plate is rotatable and axially movable along the central axis relative to the first mold portion. The index plate includes a first core and a second core. The first cavity has a first cavity injection gate for injecting mold material into the first cavity for forming the outer container. The second cavity has a second cavity injection gate for injecting mold material into the second cavity for forming the inner container. The first cavity has a further injection gate for injecting joint material for joining the outer and inner containers.

For the purpose of enabling high-accuracy detection as to whether a molded resin product is a non-defective product or a defective product and advance detection of a molded resin product that may suffer deformation or the like in the future, the present invention relates to an inspection method and a manufacturing method for a molded resin product as well as an inspection device and a manufacturing device for a molded resin product, wherein, in an inspection of a joint interface of a molded resin product divided into a plurality of members, the height positions of defect candidates are measured from the results of detecting X rays radiated via at least two paths when the X rays are transmitted through the molded resin product, which makes it possible to detect a defect with high accuracy.

A method for producing a thermoplastic container (1) for gases or liquids. First, in an injection mould having a first (28) and a second mould (29), in a first position providing each a cavity (34) for an upper (2) and a lower shell (3), producing the shells in parallel. Next, opening the mould, the shells (2, 3) remaining in a respective mould. Then, turning or shifting at least one of the two moulds such that the concave interior sides of the shells are aligned against each other and closing the mould, so that the edge regions (7, 8) of the shells come into face-to-face contact. Injection material is injected into a cavity (49) between or adjacent to the edge areas (7, 8), forming an all-round welded seam (11) between the upper part (2) and the lower part (3). Finally the mould is opened and the at least one container is removed.

An insert molding component includes a primary molding section with a concave portion formed on one surface thereof, an insert component disposed on a bottom side of the concave portion of the primary molding section, a heat-insulating component disposed in the concave portion of the primary molding section and disposed on a top of the insert component, and a secondary molding section disposed in contact with the one surface of the primary molding section.

An end member assembly is dimensioned for securement to an associated flexible spring member. End member assembly includes first, second and third end member sections. First end member section includes a first outer peripheral wall portion. Second end member section includes a second outer peripheral wall portion. Second end member section is positioned in abutting engagement with the first end member section such that a groove extends peripherally around first and second end member sections between first and second outer peripheral wall portions. Third end member section is injection molded in situ with first and second end member sections such that third end member section extends peripherally around first and second end member sections within groove. Gas spring assemblies and vehicle suspension systems are also included.

A resin molding method includes a first molding step, a sliding step, a second molding step and a mold opening step. In the first molding step, first molded part supported in a fixed mold and a second molded part supported in a die slide mold are molded in different positions in a second direction. In the sliding step, the movable mold is removed in a first direction and the first molded part and the second molded part are aligned by the die slide mold is moved in the second direction. In the second molding step, the movable mold is clamped again with the fixed mold and resin is injected into engaged portions. Each of the first molded part and the second molded part includes at least one wall extending in the first direction, and in the second molding step, the first molded part and the second molded part are engaged with each other at sides of the walls extending in the first direction.
