An assembly of fluid conduit parts is disclosed along with a method of assembling, a method of manufacturing and an apparatus for manufacturing the one of the fluid conduit parts. The assembly includes a blow molded part having a first portion. A second part includes a tapered section and a sealing flange extends from the first portion towards a central axis of the first portion at a distance, an end of the sealing flange defines an opening. The second part inserts into the opening and at least part of the tapered section is of a size larger than the opening. The sealing flange flexes upon insertion of the second part into the opening to define a contact surface between the tapered section and the sealing flange that extends around a perimeter of the tapered section where the sealing flange contacts the tapered section.

A molding-forming method, a molding mold, and a molding production apparatus with which efficient burrs removal is possible without requiring a large apparatus. A molding production method includes, in addition to a molding being formed inside a mold, burrs formed around the molding are separated from the molding. After formation of the molding, air is blown inside the mold on at least a portion of the burrs formed around the molding to cool the same, a projecting member is projected toward the cooled burrs, and the burrs are separated from the molding. After pressing the burrs toward the projecting member by the air blowing, the burr is pressed toward the mold surface facing the projecting member by projection of the projecting member to separate the burr from the molding.

Systems and methods for making a reduced material container (105) are provided that hold a preform (130) adjacent to an open end (165) of the preform (130), stretch the preform (130), close a mold (110, 120) about the stretched preform (175) to form a truncated preform (185), and introduce a pressurized fluid (160) into the truncated preform (185) to expand the truncated preform (185) and form the reduced material container (105). A stretch rod (125) can be inserted into the preform (130) to mechanically stretching the preform (130). The mold (110, 120) accepts the preform (130) at a first end (135) thereof, has an open state and a closed state, and the closed state forms a cavity (140) defining an internal surface (145) having a second end (150) located remotely from the first end (135). A first length (155) is defined by a distance between the first end (135) and the second end (150), the stretch rod (125) mechanically stretching the preform (130) to a second length (170), the second length (170) being greater than the first length (155).

A method for manufacturing an arrangement for the transport of media includes a base body formed as a blow-molded part and at least one functional element, in which a preform consisting of polymeric material and at least one functional element are provided and arranged in a blow mold, wherein the base body is formed from the preform, wherein the preform bears against the functional element during forming, wherein the blow mold has a first mold element and a second mold element, wherein the base body is formed from the preform between the first mold element and the second mold element, wherein the first mold element and the second mold element bear against the functional element in such a way that excess material produced from the preform in the area of the functional element during blow molding can be removed.

An object of the present invention is to produce a double-sided carpet type skin-equipped hollow molded article so as to prevent degradation of aesthetic appearance of the hollow molded article. The double-sided carpet type skin-equipped hollow molded article includes: a hollow molded article main body made of a thermoplastic and having a front surface wall and a back surface wall; and skins integrally bonded to the respective front and back surface walls. A first skin bonded to the front surface wall is a napped-type skin. A second skin bonded to the back surface wall is a skin having a thickness smaller than a thickness of the first skin. A wall surface to which the first skin is bonded protrudes outward more than a wall surface to which the second skin is bonded in a parting line of the hollow molded article main body. The first skin has a large thickness and is a napped-type skin. Therefore, obtained is an effect that a nap raised after deburring and cutting masks a cut portion.

A method for producing a plastic container by internal pressure forming including arranging a hose-shaped preform between the molding dies of a mold, formed having a mold cavity; closing the mold and forming or preforming a container from the preform by internal pressure, wherein a circumferential section of the preform is pressed through a mold gap into a chamber surrounding the mold cavity and is pressed in the chamber against claw pairs having stationary inner retaining claws and movable outer tear-away claws; and laterally moving the outer tear-away claws, causing the circumferential section between the outer tear-away claws and the inner retaining claws to be torn open and the container to be split into two container halves. Also disclosed is a mold suitable for performing the method.
