A method of manufacturing a clamping ring for a cold-expansion joining system includes providing an extruded pipe part made of a cross-linked polymeric material where, while extruding the pipe part, the inner diameter is formed bigger than the outer diameter of a flexible cross-linked polymeric pipe onto which the clamping ring is positioned before making a pipe connection; providing an injection molded annular part having an inner diameter formed smaller than the inner diameter of the extruded part; and bonding the parts together to form a clamping ring having an inward protruding stop edge at one of its ends. The embodiments further relate to a clamping ring formed from an extruded pipe part made of a cross-linked polymeric material and an injection molded annular part bonded together to form a unitary structure including an inward protruding stop edge at one of its ends.

A reinforcing component for a structure of an aircraft or spacecraft has a first component region for reinforcing at least one other element, and at least one second component region, which is permanently connected to the first component region. The reinforcing component is formed using a thermoplastic plastics material in each of the first component region and the second component region. In the first component region, the thermoplastic plastics material forms a matrix in which continuous reinforcing fibres are embedded. In the second component region, the reinforcing component comprises discontinuous reinforcing fibres or is free of reinforcing fibres.

An induction sealing head, an induction sealing system and a method for sealing a closure to an aperture of a container are disclosed. The induction sealing head is for sealing a closure to an aperture of a container, and includes an induction coil, wherein the induction coil is wound about an axis, and has a first portion lying substantially in a first plane perpendicular to the axis, and a second portion stepped out of the first plane, and lying substantially in a second plane parallel with the first plane.

A polyolefin-containing seam tape is described herein. The polyolefin may be at least one of a homopolymer, copolymer, terpolymer, or a polymer blend of polyethylene, polypropylene, or a combination of the two. The seam tape may be used to form a bonded, reinforced, or waterproofed seam. The seam tape may be used in equipment or apparel that may or may not be recyclable.

The invention relates to a method for welding a connection between a first joining surface of a first molded part and a second joining surface of a second molded part, which by means of a clamping device are moved and braced with their joining surfaces in contact with one another, wherein the first molded part is at least partially transparent for a primary beam of a first radiation source and at least partially absorbent for a secondary beam of a second radiation source, and the second molded part is at least partially absorbent for the primary beam, wherein sequentially the second molded part is irradiated with the primary beam and the first molded part is irradiated with the secondary beam.

A laser welded structure is formed by laser welding together a resin molded body formed from a thermoplastic polymer alloy containing a crystalline resin and an amorphous resin and a metal body made of a metal. A glass transition temperature of the amorphous resin is lower than a melting start temperature of the crystalline resin.

The present invention provides a vehicle lamp comprising a lens molded article (1) and a housing molded article (2) laser-welded to each other, the lens molded article (1) comprising a methacrylic resin composition which comprises 70 to 99.9% by mass of a methacrylic acid ester monomer unit and 0.1 to 30% by mass of a unit of an additional vinyl monomer copolymerizable with the methacrylic acid ester monomer and satisfies conditions (a) to (c), and the housing molded article (2) comprising a resin which satisfies a condition (d): (a) MW is 90000 to 250000; (b) a mass (MFR-1) of the methacrylic resin composition emitted according to ISO1133 standard at 230° C. and 3.8 kg for 10 minutes is 0.2 to 12 g/10 min; (c) when a mass of the methacrylic resin composition emitted according to the ISO1133 standard at 230° C. and 10 kg for 10 minutes is defined as MFR-2, MFR ratio=(MFR-2)/(MFR-1) is 4.5 or more; and (d) a mass (MFR-3) of the resin emitted according to the ISO1133 standard at 220° C. and 10 kg for 10 minutes is 2 to 45 g/10 min or smaller.

The present invention relates to a motor vehicle luminous device including at least one first portion that is transparent to at least one laser beam, the portion having at least one first polymer material, and at least one second portion that absorbs the laser beam and is transparent to at least some of the visible spectrum, including at least one second polymer material, the second portion being laser welded to the first portion.

A product includes a first component, a second component and an adhesive. The adhesive fills an interior space that is surrounded by the first component and the second component. The second component comprising an inlet that communicates between an exterior space of the second component and the interior space so as to enable the adhesive to be injected into the interior space. The inlet comprising a tapered portion that narrows from the exterior space towards the interior space.

A method for forming a pipe elbow comprises cutting a first precursor from a pipe. The pipe has an inner diameter surface and an outer diameter surface and a central longitudinal axis. The first precursor has a first end and a second end off parallel to the first end. Machining forms an interior surface having an arcuate centerline. Machining forms welding interfaces at the first end and the second end.
