The molding apparatus may include a frame that is positioned on a periphery of the mold and is movable relative to the mold, wherein a suction part for suctioning the thermoplastic resin is provided in a contact surface of the frame to contact the thermoplastic resin, and the suction part is provided in a linear shape along with a longitudinal direction of the frame positioned on the periphery of the mold.

A method for producing a half shell for a hollow body includes applying a preheated plastics sheet to a first tool half that forms a die, and then pre-stretching the plastics sheet, at least in certain regions thereof, by blowing or suctioning away, at least certain sections of the plastics sheet from the first tool half. The plastics sheet is then suctioned or pressed, via pressure or negative pressure, onto the first tool half, at least in certain regions.

The invention relates to a method for producing hollow bodies from thermoplastic material by using an at least three-part blow-molding tool with at least two blow-mold halves (1a, 1b), which define a mold impression, have part-cavities (5a, 5b) and can be displaced toward one another and away from one another in the sense of an opening and closing movement, and also with at least one central tool (2), which is displaceable transversely in relation to the opening and closing movement of the blow-mold halves (1a, 1b), the method comprising the extruding or providing and arranging of at least two molten performs (7) of thermoplastic material in web form between the blow-mold halves (1a, 1b) in an opened receiving position, the bringing to bear of the preforms (7) in the part-cavities (5a, 5b) of the blow-mold halves (1a, 1b) and molding of them into shells (10) using sealing elements which are provided on the central tool and are extended from the central tool for the purpose of sealing off the part-cavities before or while the part-cavities are subjected to differential pressure; the joining of at least one insert (9) in at least one shell (10) by using the central tool (2) arranged between the blow-mold halves (1a, 1b) and the joining of the shells (10) to form the closed hollow body by closing the blow-mold halves (1a, 1b) while applying clamping force and, if appropriate, the final blow molding of the hollow body.

Provided are: a pipe-shaped integrally molded article which is formed by molding a polyphenylene sulfide resin composition, and which has, at one or more portions thereof, at least one selected from different-shape sections, bent sections, and different-diameter sections, the pipe-shaped integrally molded article being characterized in that the total length L (mm) thereof is 1000 or more, and the ratio (L/D) of the total length L (mm) to the outer diameter D (mm) of the pipe-shaped integrally molded article is 20 or more: and a production method for the pipe-shaped integrally molded article. According to the present invention, it is possible to efficiently provide a pipe-shaped integrally molded article having a desired large length and including a three-dimensionally complicated shape, by using a PPS resin composition having excellent heat resistance and chemical resistance.

A vessel is configured to hold a product in an interior region formed in the vessel. The vessel is formed using a blow-molding process in which a multiple layer parison is blow molded to form the vessel. The multiple layer parison is formed in an extrusion process in which a number of extruders are arranged to co-extrude associated inner and outer parisons to establish the multiple layer parison.

A plastic sheet cassette includes a first frame member pivotably coupled to a second frame member, and a plastic sheet is fixedly supported by male and female parts provided on the first and second frame members. A thermoforming apparatus includes a cabinet, a heating source, a vacuum source, a platform, and a fixing frame that supports the cassette so as to be removable, and is vertically movable between the heating source and the vacuum source in the cabinet. The fixing frame can be stopped or released at any desired level in the cabinet and supports the cassette so that the sheet is heated at the upper level by the heating source and is brought into close contact with a prototype at the lower level by the vacuum source for making a mold having the same shape as the prototype.

A method of manufacturing bulked continuous carpet filament which, in various embodiments, comprises: (A) washing a plurality of flakes of recycled PET; (B) providing a PET crystallizer; (C) after the step of washing the plurality of flakes, passing the plurality of flakes of recycled PET through the PET crystallizer; (D) at least partially melting the plurality of flakes into a polymer melt; (E) providing a multi-rotating screw (MRS) extruder having an MRS section; and a vacuum pump in communication with the MRS section; (F) using the vacuum pump to reduce a pressure within the MRS Section; (G) after the step of passing the plurality of flakes through the PET crystallizer, passing the polymer melt through the MRS Section; and (H) after the step of passing the polymer melt through the MRS extruder, forming the polymer melt into bulked continuous carpet filament.

Illustrated and described are a method and a device for laminating a profiled fibre moulding with a thermoplastic film. The film is laminated onto a surface of the fibre moulding to be coated by heat and differential pressure. To improve the lamination of the fibre moulding and to achieve uniform lamination thicknesses over the entire fibre moulding, the method includes the following steps: fixing at least an edge of the fed film to a base plate, heating the film, deforming the film via a moulding tool, feeding the fibre moulding, joining the fibre moulding to the pre-formed film, and removing the laminated fibre moulding.

A polyetheretherketone pipe of length greater than 250 meters and a residual stress of less than 5 MPa may be made using a calibrator device 2 which includes a cone shaped opening 6 arranged to receive a molten extruded pipe shaped polymer. Attached to the front member 4 is a vacuum plate 14a and successive vacuum plates 14b-14h are attached to one another to define an array of vacuum plates, the vacuum plates being arranged to allow a vacuum to be applied to a pipe precursor passing through opening 16. The vacuum plates 14 also include temperature control means for heating or cooling the plates and therefore heating or cooling a pipe precursor passing through the openings. With a vacuum applied to opening 6, 16 and heating/cooling the plates, an extruded hot plastics pipe is inserted into calibrator 2 via opening 6 and conveyed through opening 16 in plates 14, whereupon it is urged by the vacuum against the cylindrical surface defined by plates 14 to maintain its shape and the temperature of each plate is controlled to control the rate of cooling of the pipe precursor passing through. The pipe may be cooled at a relatively slow rate so that a pipe made from a relatively fast crystallising polymer crystalises and the crystallinity of the pipe along its extent and throughout its thickness is substantially constant.

A thermoforming system and related methods for manufacturing thermoplastic parts, such as interior panels for aircraft, may include a roll-to-roll operation and a forming press having at least one selectively rotatable tool. The rotatable tool, which may include a mold and/or a die, may be multifaceted, such that different faces of the tool have different mold arrangements for different forming characteristics.
