An aluminum transducer chassis prepared by a process having the following steps: performing an extrusion using a die and an aluminum billet to create an extruded chassis, wherein the die has a cross sectional shape of the transducer chassis; and cutting the extruded chassis to a plurality of predetermined lengths, each length corresponding to the length of a transducer chassis.

US9718500 — STRUCTURE OF HYBRID FRONT PILLAR — Hyundai Motor Company (Korea) — The present invention relates to a structure of a front pillar for a vehicle, and more particularly, to a structure of a hybrid front pillar, which is capable of reducing a weight of the front pillar and a number of components by utilizing an aluminum die casting, aluminum extrusion, or a carbon fiber reinforced plastic, and which can increase rigidity, for example, to withstand damage in a small overlap collision test, by utilizing a mutual insertion structure and a mechanical connection method. A structure of a hybrid front pillar of a vehicle includes a front pillar lower portion made of an aluminum extrusion which is disposed at a front side of a front door unit of a vehicle, and has a lower end coupled to a side connecting member; and a front pillar upper portion which is made of die cast aluminum and is disposed at an upper side of the front pillar lower portion, and coupled to the front pillar lower portion, in which a recessed portion is formed at one side of the side connecting member such that the lower end of the front pillar lower portion is inserted into the recessed portion, and a mounting portion is formed at a lower end of the front pillar upper portion such that an upper end of the front pillar lower portion is inserted into the mounting portion, thereby significantly reducing a weight of the vehicle body, enhancing rigidity of the front pillar, and omitting reinforcing components.

US9068358 — WALL PANEL SYSTEMS FOR RIGID WALL PANELS — Exterior Wall Systems Limited (Canada) — Wall panel systems are provided. The systems use interlocking brackets to attach photovoltaic (PV), ceramic, or other rigid wall panels to an exterior wall of a building. The interlocking components include a plurality of wall mounting brackets configured to carry the dead loads of the respective wall panels, and a plurality of panel brackets that may be quickly hung from the wall mounting brackets. The wall mounting bracket 140 and the panel bracket 150 may be fabricated from aluminum extrusions cut to specific lengths. The extruded parts may have a milled or an anodized finish. The wall mounting brackets are configured to be operatively fastened to an exterior wall surface, while each of the panel brackets is adhesively attached to the rear surface of a respective panel. Each of the wall mounting brackets and the nested panel brackets is substantially similar in dimension and configuration. Further, the system is configured to allow wall panels to be attached to the bracket assemblies in any sequence. A method for attaching architectural wall panels is also provided herein.

US8650927 — FORMING DEVICE FOR THIXOEXTRUSION AND METHOD THEREOF — Korea Institute of Industrial Technology (Korea) — According to the apparatus and method, metals can be molded under a low extrusion pressure, the life of the apparatus is prolonged, the strength of the metal products is improved, the ignition of the metals is inhibited during processing, the amount of a protective gas used is reduced, and the formation of welding lines is inhibited. In accordance with a first aspect of the present invention, the above and other objects can be accomplished by the provision of a thixoextrusion molding apparatus comprising: a container having a first through-hole storing 10 to 30 parts by weight of a semi-solid billet therein and a heater installed outside the first through-hole to maintain the temperature of the semi-solid billet constant. A die body support is coupled to the back of the die body inside the die ring and has a plurality of coolant inflow/outflow holes so as to change the phase of the extruded semi-solid billet to a solid extrudate, wherein the semi-solid billet is selected from aluminum alloys and magnesium alloys.
