An apparatus, method and manufacture utilizes additive manufacturing techniques to produce architectural manufactures such as windows and doors. The manufactures may have a composite construction and may feature inclusions like metal plates and reinforcements. The model used for controlling the manufacturing process may be derived from digital scanning of the structure on which the manufacture is used. Optionally, a finite element analysis is used to test the model and alter it in response to stress and/or thermal requirements.

In production of aluminum alloy members by a plastic working of a heat-treatable aluminum alloy extrusion, cracking during the plastic working is eliminated or minimized at low cost as compared with techniques including solution treatment or restoration treatment. An aluminum alloy production system includes an extruding press, a cutting device disposed downstream from the extruding press, and a conveyer and a plastic working machine each disposed in parallel with the extruding press. The extruding press hot-extrudes a heat-treatable aluminum alloy to give an extrusion. The cutting device cuts the extrusion to a predetermined length and isolates the extrusion from the extruding press. The conveyer conveys the extrusion to the plastic working machine, where the extrusion has been cut by the cutting device to a predetermined length. The plastic working machine imparts a plastic working to the extrusion conveyed by the conveyer to form the extrusion into an aluminum alloy part.

A method for preparing a high-strength extruded profile of an MgZnSnMn alloy is composed of a solid solution treatment at two stages to a billet, a high-temperature pre-aging to the billet, a low-temperature rapid extrusion and a low-temperature aging treatment to a profile. The MgZnSnMn alloy includes the following elements in mass percent: 5.8-6.2% of Zn, 3.0-3.5% of Sn, 0.25-0.45% of Mn, unavoidable impurities of 0.05% or less, and the balance magnesium. The MgZnSnMn magnesium alloy profile has a fine grain size of about 10-20 m and a dispersed second phase, so a high strength and a good elongation can be obtained therein, and a tensile strength of 350 MPa or more, a yield strength of 280 MPa or more, and the elongation of 12% or more. In addition, the profile has a high extrusion production efficiency and a highyield, and a low extrusion cost.

An efficient method for producing spring strut forks for motor vehicles is presented. In each case two spring strut forks are produced from a metallic extruded profile as a starting product. The extruded profile has a central, middle main chamber and four longitudinal chambers which are arranged offset with respect to one another over the circumference of the main chamber. Wall portions of the main chamber which are situated between the longitudinal chambers are removed, and the extruded profile is severed into two semifinished parts. Each semifinished part has one cylinder portion and two oppositely situated arm portions which project relative to the cylinder portions. The semifinished parts are subsequently mechanically machined, and one spring strut fork is produced from each semifinished part.

An extruded rail assembly including a first multi-channel extrusion having at least two tubular channels connected by a center rib, and having a joining end configured for joining at a predetermined angle to a joining end of a second multi-channel extrusion. The second multi-channel extrusion includes at least two tubular channels connected by a center rib, and having a joining end configured for joining at the predetermined angle to the joining end of first multi-channel extrusion. The joining ends of the first and second multi-channel extrusions are configured such that the center ribs complementarily engage as a joining surface.

A method and to a system for producing open or closed annular structural components made of light metal and alloys thereof, preferably of magnesium or magnesium alloys, having a two-dimensional or three-dimensional structure by means of extrusion, wherein the extruded profile exiting the die of the extrusion press is formed into a helical shape by way of one or more guide tools, and more particularly such that the ends of the helical shape are separated from the extruded strand in the region of the overlap and formed into a two-dimensional or three-dimensional structural component in a shaping device.

The invention relates to a method and a device for producing an extruded product. In the method an extrusion device is provided comprising: a container (7); a first container bore (5), formed in the container (7) and in which a first extrusion punch (10) is arranged; a second container bore (6), formed in the container (7) separately from the first container bore (5) and in which a second extrusion punch (11) is arranged; and a moulding tool (15) with a moulding cavity (14), which are connected to the first and the second container bore (5, 6). The method further comprises the following: arranging a first material billet (8) made of a first material (2) in the first container bore (5); arranging a second material billet (9) made of a second material (3) which differs from the first material (2) in the second container bore (6); and extruding an extruded product (1) in which the first and the second material (2, 3) are connected in a form-fitting and integrally bonded manner, comprising the following: feeding the first extrusion punch (10) in the first container bore (5) in such a manner that the first material (2) is thereby pressed into the moulding cavity (14) of the moulding tool (15) and thereby formed; feeding the second extrusion punch (11) in the second container bore (6) in such a manner that the second material (3) is thereby pressed into the moulding cavity (14) of the moulding tool (15) and thereby formed; and joining the first and second material (2, 3) in a form-fitting and integrally bonded manner to form an extruded product (1) in the moulding tool (15).
