A method for the production of an FMV hybrid component includes braiding a dry hybrid fibre thread onto a core element, where a hybrid fibre braid is formed, and obtaining a fibre core composite. The method further includes reshaping the fibre core composite and impregnating and consolidating the hybrid fibre braid on the core element.

An add-on part (10) for connecting to a component (30). The add-on part (10) has a longitudinal axis (A) and a welding section (11) to be welded to the component (30) by torsional ultrasonic welding. The welding section (11) has a contact surface (12) for contact with a torsion sonotrode (70) and a welding surface (13) for connecting to the component (30). The welding section (11) is delimited, at least in some sections, by an inner vibration-decoupling zone (14). The inner vibration-decoupling zone (14) extends, at least in some sections, at an inclination to or parallel to the longitudinal axis (A). The method comprises a) bringing the welding surface (13) in contact with a welding region (31), b) applying a force to the contact surface (12) such that the welding surface (13) is pressed against the welding region (31), and c) introducing a torsional ultrasonic vibration into the welding section.

The invention relates to a method for the ultrasonic welding of two plastic components using a sonotrode, wherein the energy for the welding is introduced into the plastic components via at least one or more pins of the sonotrode, wherein the two plastic components are welded to one another step by step, wherein the respectively subsequent step of the welding is carried out in a region which has already been loaded and relieved of tension as a result of the preceding step of the welding.

The invention relates to a monobloc part forming a front block for motor vehicle including a structural portion forming an energy absorption system, and a moulded semi-structural portion forming at least an aerodynamic system, the semi-structural portion being overmoulded on the structural portion.

A plastic welder comprising a control unit comprising a bulkhead assembly, a torch assembly comprising a torch hybrid connector, and a hybrid cable hose assembly comprising a hybrid cable hose including a threaded portion, a first overmolded portion, a second overmolded portion, wherein the torch assembly is removably attachable to the bulkhead assembly of the control unit by the hybrid cable hose assembly.

A bumper for a vehicle, including at least one profile, in particular an open profile, from a first material, having at least one ribbed structure formed from ribs from a second material, the ribbed structure being disposed along the profile at least in portions and at least in portions being connected to the profile in a force-fitting, form-fitting and/or materially integral manner in order for the profile to be reinforced. The bumper meets the requirements set in the event of collision loads and can be optimized in terms of load is achieved in that the ribbed structure is formed from fiber-reinforced plastic and has at least one first region and one second region, which differ from one another in terms of at least one property.

A method of manufacturing a bumper for impact absorption and a bumper for the impact absorption manufactured from the same are provided. The method includes: filling solid salts in a mold, injecting a molten metal into the mold, and solidifying the molten metal with the solid salts to obtain a solidified product, spraying water onto the solidified product to dissolve the solid salts, which results in obtaining a porous metal having pores, disposing the porous metal in an injection mold, and injecting-inserting a resin composite into the injection mold to surround the porous metal while filling at least a part of the pores in the porous metal.

Disclosed is a resin composition for an exterior material of a vehicle. The resin composition may include an amount of about 40 to 90 parts by weight of polypropylene resin having a melt index of about 70 to 110 g/10 min; an amount of about 10 to 40 parts by weight of an olefin block copolymer including an ethylene-based repeating unit and a -olefin-based repeating unit having 4 to 30 carbon atoms; an amount of about 10 to 20 parts by weight of needle-shaped inorganic filler having an aspect ratio of about 5 to 10; and an 0.01 to 5 parts by weight of laser-transmitting black colorant, wherein all the parts by weights based on 100 parts by weight of the resin composition. In particular, an average transmittance may range from about 0.01 to about 1% or less in a wavelength of about 380 to 700 nm, and an average transmittance may range from about 15% or greater and less than about 100% in a wavelength of about 800 to 1200 nm.

A welding apparatus is suitable for welding polymeric materials, and particularly but not exclusively those that may be thin or brittle. A welding apparatus is provided for welding polymeric materials along a weld zone of the polymeric material. The welding apparatus has a carrier for supplying heat to the weld zone to cause melting of the polymeric material, wherein the heating element is arranged to reciprocate relative to the carrier between a retracted and an extended configuration, such that as the element moves from the retracted to the extended configuration the heating element melts and penetrates the surface of the polymeric material. The carrier also has a trailing contact surface trailing the heating element along the weld zone arranged to constrain molten polymeric material in the weld zone. The heating element is also arranged to reciprocate relative to the trailing contact surface.

An injector includes a nozzle provided with a valve seat, a valve body which is seated on or separated from the valve seat, and a displacement means for displacing the valve body. A resin flow passage through which molten resin flows is formed inside the nozzle. The resin flow passage includes a cross-sectional area varying portion having a cross-sectional area, in a direction orthogonal to a flow direction, which varies with increasing distance toward or away from the valve body. The displacement means is capable of stopping the valve body in any position in the cross-sectional area varying portion.
