Apparatus and method for forming retaining elements by forming
A method of forming a retaining device with hooks, wherein: a molding strip is provided that presents an inside face and an outside face, and that has a plurality of cavities, each cavity defining a stem extending from the outside face towards the inside face and including an end forming a head that extends from the stem towards the inside face of the molding strip; and the molding strip is positioned on rotary drive means, comprising at least two rollers, the inside face of the molding strip being arranged to bear against the drive means.
Method and Device for Laminating a Profiled Fibre Moulding
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.
Implantable medical device with varied composition and porosity, and method for forming same
A method for forming a thermoplastic body having regions with varied material composition and/or porosity. Powder blends comprising a thermoplastic polymer, a sacrificial porogen and an inorganic reinforcement or filler are molded to form complementary parts with closely toleranced mating surfaces. The parts are formed discretely, assembled and compression molded to provide a unitary article that is free from discernible boundaries between the assembled parts. Each part in the assembly has differences in composition and/or porosity, and the assembly has accurate physical features throughout the sections of the formed article, without distortion and nonuniformities caused by variable compaction and densification rates in methods that involve compression molding powder blends in a single step.
THERMOFORMING PROCESS FOR PATTERNED FABRIC SUBSTRATE
Disclosed herein is a composite of a thermoformable fabric and an elastomer which together have been subjected to thermoformable moulding to provide a 3-dimensionally thermoformed fabric article in the form of a textile or in the form of the whole or part of a garment. The article presents an appearance that is substantially free of permanent wrinkles. Also disclosed herein is a process to make said article.
PASSENGER SEATBACK ASSEMBLY WITH THERMOPLASTIC ELEMENTS
A thermoplastic seatback for a passenger seat includes a thermoplastic peripheral structural frame for attachment to a seat assembly and a thermoplastic diaphragm overmolded onto a forward face of the frame. An aircraft passenger seat and a method of constructing a passenger seatback is also disclosed.
Receptacle having a premolded insert with a surface irregularity
A receptacle, particularly a closed plastic ampoule produced in a blow molding method and filled in the mold, has a sleeve-type neck part (1) connected to a receptacle body (3) as an axial extension. The neck part forms a seat (11) for a pre-shaped insert (5) and is integrally molded in the mold onto a circumferential surface (9) of the insert (5). The circumferential surface (9) is equipped with at least one surface irregularity (21) having an enclosed base surface such that, due to the integral molding of the neck part (1) onto the circumferential surface (9) of the insert (5), a positive fit is present between the insert and the neck part (1). The fit forms a fixing element. The axial extension of the base surface of the surface irregularity (21) is only a small fraction of the axial extension of the circumferential surface (9).
Multi-barrier bottles having tabbed preforms, and methods of forming the same
Multi-barrier bottles having tabbed preforms, as well as methods of forming the same are disclosed. A tabbed preform includes an elongate body extending into a cavity of a first barrier, where the cavity is defined by at least one piece having a recess therein. The tabbed preform further includes at least one preform extension piece extending from the elongate body at a predetermined distance from a top surface of the elongate body. The at least one preform extension piece is sized and shaped to correspond to a size and a shape of the recess.
THERMOFORMED ARTICLE WITH CO-INJECTED FEATURES
A thermoformed article is disclosed that includes a self-supporting structural base layer, a covering applied to a first side of the base layer, and one or more secondary features co-injected upon a second side of the base layer. The covering and the secondary features of the thermoformed article are applied to the base layer during the same molding operation. Also disclosed is a process for forming a thermoformed article that includes placing a covering in a mold tool as a first layer, placing a self-supporting structural base layer in the mold tooling as a second layer, closing the mold tooling with the covering and base layer, and co-injecting upon a side of the base layer opposite to the covering one or more secondary features.
Liners and methods of making liners
The present disclosure relates to liners and methods of making liners. The liners may be suitable for use with tanks and other storage/containment vessels, such as process tanks, immersion tanks, indoor or outdoor containment pits, gravity feed conduits (e.g., concrete trench, canal, or drain, etc.) for transferring or conveying liquid, grain storage tanks or containers (e.g., dielectric or electrically non-conductive liners for grain storage, etc.), etc.
METHOD OF MANUFACTURING A PLASTIC TANK
A method for producing a plastic tank includes preparing a tank wall as a hot extrudate. A reinforcing sheet is then attached to at least one region of the outer layer of the hot extrudate. After introducing the attached reinforcing sheet and the hot extrudate into a shaping tool, the shaping tool performs shaping of the hot extrudate and the attached reinforcing sheet to form the tank wall, while simultaneously enhancing the attachment of the reinforcing sheet to the tank wall.
