The invention relates to a method for producing a part made of plastic material for a motor vehicle, said part comprising at least one first section to which at least one second section is applied, in which the first section is produced. The second section of the part made of plastic material is produced by three-dimensional printing directly onto the first section of the part.

A ultrasonic welding method of joining dissimilar-material workpieces, such as sheet materials, and the joined components formed thereby. The method includes applying ultrasonic energy to a thermoplastic piece to fill a hole of a dissimilar piece to form a weld point that is made up with polymer from the thermoplastic piece. In general, the geometry of the thermoplastic piece is not altered during the process. The dissimilar piece generally has a higher melting temperate and can be metal, thermoset polymers, or other thermoplastic material. The welded pieces can be arranged in a lap, laminate, or double lap configuration. In some embodiments, the hole of the dissimilar sheet material includes undercut features that improve the mechanical interlock between the dissimilar pieces. In some embodiments, the weld point has a mushroom cap to improve mechanical interlock.

A blade for an aircraft gas turbine engine includes, in a longitudinal direction, a blade root, a shank and an aerofoil body, the aerofoil body extending in the longitudinal direction between the shank and a blade tip and in a transverse direction between a leading edge made of metal material and a trailing edge. The blade includes a blade core made of composite material having a three-dimensional woven fibrous reinforcement forming the blade root, the shank and a part of the aerofoil body. The blade also includes a skin made of composite material having a two-dimensional woven fibrous reinforcement surrounding the aerofoil body part of the blade core, the skin being interposed between the leading edge made of metal material and a front edge of the aerofoil body part of the blade core to define a thinned leading edge portion, the skin including one or more two-dimensional woven plies.

The invention relates to a mounting press for automatically mounting metallographic samples in mounting material, comprising: a pressing unit with the press cylinder, a feeding device for feeding mounting material, e.g. plastic granules, a sample loading table with a plurality of loading stations, on each of which the operator can place a sample to be mounted, a control device, a grinder and/or polisher, comprising: a device housing, at least one processing station for processing the underside of the sample, wherein the processing station comprises a grinding plate with a grinding disc for grinding the underside of the sample or a polishing plate for polishing the underside of the sample, a sample feeder with a sample removal position for providing the samples for a grinding and/or polishing process, a sample deposit position for depositing the samples after the grinding and/or polishing process, a grinding-/polishing head with a sample gripper for gripping a sample, wherein the grinding/polishing head with the sample gripper moves to the sample removal position and the sample gripper grips a sample, wherein the grinding-/polishing head with the sample gripper conveys the sample to the at least one processing station and the underside of the sample is ground or polished in the processing station, and wherein the grinding-/polishing head with the sample gripper moves the sample to the sample deposit position after the grinding or polishing process and possibly further processing steps and deposits the sample there, as well as an automated production line for mounting a plurality of samples and for processing the thus mounted samples by grinding and/or polishing samples in a program-controlled overall system comprising an automated mounting press and an automated grinder and polisher.

A molding system for applying moldable material to a pipe. An elongate mold has at least one elongate mold member movable relative another elongate mold member between open and closed positions. The mold includes a pipe support that extends generally radially into a mold cavity along a support axis. An inner end of the support is configured to support the pipe in a molding position in which an annular portion of the mold cavity extends circumferentially around the pipe. After moldable material in the annular portion of the mold cavity can support the pipe, the support is withdrawn from the mold cavity by moving outwardly along the support axis. An injector selectively dispenses additional moldable material into a space formed by the support in the existing moldable material.

A molding system for applying moldable material to a pipe. An elongate mold has at least one elongate mold member movable relative another elongate mold member between open and closed positions. In the closed position, the mold may define an elongate vent between the mold members that extends along the longitudinal axis of the mold. Air in the mold cavity displaced by moldable material received into the mold cavity vents through the elongate vent along the longitudinal axis of the mold. The mold can include a positioner that positions the mold members in the closed position while the mold is filled with the moldable material. The positioner also allows movement of the first mold member toward the open position to partially open the mold as the moldable material cures to reduce forces imparted upon the mold due to expansion of the moldable material during curing.

A method for manufacturing an insert-molded bus bar includes the steps of: preparing a first bus bar having a through hole and a second bus bar having a protrusion corresponding to the through hole; preparing a mold having therein a swaging member capable of swaging the protrusion; placing the first and second bus bars in the mold with the protrusion being inserted into the through hole; swaging the first and second bus bars using the swaging member of the mold to obtain connected bus bars that are the bus bars connected to each other; and injecting a molding material around the connected bus bars that are the bus bars connected to each other by swaging to perform insert molding using the mold and obtain the insert-molded bus bar.

Disclosed are a UV-curable resin composition for vacuum forming and a replica film of a real material including the same. The UV-curable resin composition includes a prepolymer including a urethane-containing oligomer, an acrylate monomer and a photoinitiator.

A method of and fixture for molding a product with an embedded ring. A system for molding a ring into a product including a rotational molding mold with an opening formed in the rotational molding mold sized to fit a ring. A fixture is removably couplable to the ring, wherein the ring and the fixture when coupled are removably couplable in the opening. The fixture is removed from the ring after the ring is molded into a product. A method of manufacturing a product with an embedded ring includes: coupling a ring to a fixture; clamping the fixture and the ring in an opening in a mold top; clamping the mold top to a mold bottom; rotomolding a product; unclamping the fixture from the mold top; uncoupling the fixture from the ring; unclamping the mold top and the mold bottom; and removing the product from the mold.

A mold is provided for producing a composite part comprising at least one insert and a thermoplastic overmolding covering, at least partially, said at least one insert. The mold comprises at least one clamp capable of contacting said at least one insert in order to secure said at least one insert.
