A method for producing a motor vehicle rim made of aluminum or an aluminum alloy for a motor vehicle wheel. The motor vehicle rim has a rim base delimited on opposite sides by an outer horn and an inner horn, a hub with a central recess and a hole circle and a rim center connecting the rim base and the hub to one another and acting eccentrically on the rim base in longitudinal section. The motor vehicle rim is produced in one piece and continuously in a casting mold by vacuum die casting of a casting material, wherein the motor vehicle rim has a small wall thickness of at most 15 mm at least in some regions and/or a curvature with a small radius of curvature of at most 4 mm.

A medical scope device such as an endoscope is produced using a cast aluminum process including a molten casting aluminum alloy including a maximum of 0.2 - 0.3% Si and at least 5% Zn. The process includes providing an investment casting mold, casting the aluminum alloy in the mold to create a component and removing the mold from the component, post-machining the component to meet a desired specification, and after post-machining the component, performing surface finishing, such as centrifugal barrel finishing (CBF) sufficient to remove impurities on casting surfaces by 2 - 3 mils, then coating the component with a micro-crystalline aluminum anodic coating of at least 0.5 mil thickness. A medical scope and product-by-process is also provided employing such techniques.

Vitriforming is a method for forming material into complex geometries within a vitreous substance. Liquid material is formed inside the vitreous substance through external forces applied to the vitreous forming medium. This technique can be broken down into four categories of operations: encasement, setup, forming, and extraction. All operations involve a forming medium, and a workpiece. The workpiece can be composed of any material so long as the forming medium is temperature, viscosity, and chemically compatible. The vitreous forming medium translates outside forces into the workpiece to create various geometries. This forming medium can remain a part of the final assembly or get extracted after forming takes place. Workpiece geometry is affected by forming tool geometry, initial setup, heat, and material properties. This process can be used as a fast, efficient means of forming metal or other materials with unique abilities to control material combinations, surface chemistry, texture, and overall geometry.

The invention relates to a method for producing a differential housing having at least one machined bearing body and a machined gearing. In order to improve the differential housing in terms of production technology and/or function, the differential housing which has the bearing body is cast from a nodular cast iron material before the differential housing which has the bearing body and the gearing is machined.

An array-spraying additive manufacturing apparatus and method for manufacturing a large-sized equiaxed crystal aluminum alloy ingot, comprising: a liquid aluminum spraying mechanism having array nozzles disposed in an atmospheric pressure chamber, a movable condensing mechanism disposed in the atmospheric pressure chamber below the liquid aluminum spraying mechanism, and a control mechanism. The control mechanism sends an upward guiding command to a release mechanism and issues a three-dimensional movement command to the movable condensing mechanism, such that liquid aluminum in the liquid aluminum spraying mechanism is sprayed at the surface of the movable condensing mechanism in a continuous array of liquid flows according to a preset path and is rapidly condensed to form an ingot. Also disclosed is an additive manufacturing method employing the apparatus.

Methods for manufacturing rotary target materials that allows a material to be cast in a melting zone of a casting vessel while the vessel is rotated such that a melting zone is below a casting zone. The vessel is sealed and the pressure inside the vessel is reduced and the exterior of the vessel is heated. The melting zone of the vessel is heated to a temperature that melts the material and releases any trapped gasses which can be pumped out using the vacuum pump. Once the melting zone and molten material have reached a specified temperature, outgassed, and the casting zone has reached a temperature to maximize adhesion and reduce voids and defects, the vessel is rotated until the melting zone is directly above the casting zone to transfer the material from the melting zone to the casting zone.
