Molding unit (1) for the forming of a container (2) provided with a hollow recess (3), comprising: a mold (5) provided with a lateral wall (6) defining a cavity (7) and provided with a pocket (9) that comes out into the cavity (7); a boxing device (11) comprising: an insert (12) mounted in translation in the pocket (9) relative to the lateral wall (6) and provided with at least one passage (81) opening out; an actuator (16) integral with the insert (12) and provided with a piston (17) mounted in a chamber (22) defined in the wall (6) of the mold (5), the piston (17) subdividing the chamber (22) into a rear half-chamber (22A) in communication with a primary fluid duct (46), and a front half-chamber (22B) in communication, on the one hand, with a secondary fluid duct (50) and, on the other hand, with the pocket (9).

A method of manufacturing a resin-laminated board by preparing a pair of first and second split molds each of which is provided with a cavity; positioning two sheet materials made of a thermoplastic resin between the first and second split molds with the cavities of the first and second split molds opposed to each other; forming a plurality of recesses by recessing a first sheet material toward a second sheet material with use of a plurality of protrusions provided to the first split mold; and welding bottoms of the recesses to the second sheet material by clamping the pair of first and second split molds to obtain a resin-laminated board with a hollow structure. A mold includes a plurality of piece members, disposed at the cavity of the first split mold; and includes the protrusions and male screws provided to base ends of the protrusions.

A stretch-blown plastic container, includes a container body which encloses a filling volume with a container bottom; a container neck which adjoins an opposite end of the container body, having a container opening and an integrated handle region, the handle region being hollow and joined to the filling volume which is enclosed by the container body; and between the handle region and the container body, a through opening recessed and bordered over its entire periphery by wall parts of the container body and of the handle region which have been welded to one another.

A plastic molded lip structure may extend along a perimeter of a planar element and may include an outer wall, an inner wall, structural portions, and protruded features. The outer wall may extend in a normal direction from the planar element. The inner wall may be disposed in an inward direction relative to the outer wall. The structural portions may be disposed along structural sections of the perimeter and may include first portions of the inner wall and of the outer wall. The first portions may be disposed parallel to the inner wall and separated from the first portions by a first distance along the structural sections. The protruded features may be interposed between two structural portions and an inner wall may be separated from second portions of the outer wall by a second distance that is greater than the first distance.

A fuel tank production apparatus includes a forming mold and a cooling mold. The forming mold has a protruding ridge portion on a molding surface thereof and is configured to form a primary molded article while forming a bead-shaped portion so as to provide a recess on an outer surface. The cooling mold is configured to cool the primary molded article while crushing the bead-shaped portion by cooling blow pressure and deforming the bead-shaped portion into a rib-shaped portion.

A method of manufacturing a sole structure includes providing a plate within a cavity of a mold. The plate includes a base and a rib, and the base includes a first surface and a second surface. The first surface faces the upper, the second surface faces away from the first surface, and the rib projects from the second surface of the base. Moreover, the method includes providing a preform bladder member within the cavity of the mold, wherein the preform bladder member including a first member and a second member. The method additionally includes forming a bladder from the first and second members using the mold. Also, the method includes attaching the first member to the plate using the mold. Attaching the first member to the plate includes shaping the first member according to surfaces of the rib.
