A processing system and method for processing a cast raw casting has a spray system for cooling the raw casting. The spray system has at least one nozzle device for at least temporally, locally, or quantitatively variable application of a free-flowing medium to at least one section of the raw casting. The processing system also has a temperature measuring device for measuring the temperature on at least one section of the raw casting and a monitoring device for controlling and adjusting the nozzle device as a function of the measured temperature.

A fixed scroll compressor body includes a scroll compressor body casting. The casting has a central body portion having a plate-like base with a spiral scroll rib projecting from the base at a right angle thereto. The spiral scroll rib includes a volume between the spiraled ribs for the compressing of refrigerant. The spiral scroll rib spirals from a central region of the plate-like base to an outer wall of the central body portion. The casting further includes a first inward-protruding portion that protrudes from the outer wall into the volume. A distance that the first inward-protruding portion protrudes into the volume is greater than a thickness of the first inward-protruding portion such that removal of the first inward-protruding portion results in a first intake opening in the outer wall. The first intake opening provides a path for a flow of refrigerant into the volume.

A permanent mold can include mold halves which can be joined together on a mold separation plane. The mold halves of the permanent mold are joined together such that the permanent mold has a cavity, which defines the shape of the helix or the shape of a bent-up helix, when the permanent mold is joined together. The specified helix or the bent-up helix has a flattened profiled winding cross-section which has two opposite flat faces, an outer face and an inner face opposite the outer face. The mold separation plane runs at least partly along the flat faces from the inner face to the outer face, wherein the permanent mold has a bulge which extends along the mold separation plane and protrudes into the cavity at least in a region in which the mold separation plane runs along one of the flat faces such that the cast body is provided with recesses on the flat faces.

A post-processing device of a cast product is configured to post-process the cast product in which a plurality of components is integrated. In particular, the post-processing device may include i) a first press mold configured to trim cast scraps of the cast product and process at least one hole into the cast product, and ii) a second press mold configured to calibrate dimensions of the plurality of components and fasten hardware to the at least one hole.

A thermally stable component formed of a tempered aluminum alloy casting which reduced costs is provided. The aluminum alloy typically has an elongation of at least 8% after casting, which is preferred for self-piercing rivet processes. The aluminum alloy leaves a casting facility in the as-cast (F temper) condition. The cast aluminum alloy is then shipped to another entity, such as an OEM, and is subjected to an artificial aging process, such as on the

OEM's existing paint line, rather than at the casting facility. The artificial aging process typically includes electrodeposition coating and curing. The components that can be formed by the reduced cost method include lightweight automotive vehicle components, including structural, body-in-white, suspension, or chassis components, such as front shock towers, front body hinge pillars, tunnels, and rear rails.

Methods for forming metal articles are provided. The methods include forming foam casting molds from polylactic acid for use in lost foam and sand casting processes. The PLA-based foam casting molds advantageously reduce cycle time, reduce overall cost, increase reusability of the foam casting molds, reduce costs associated with shipping the foam casting mold, and improve yield and quality of cast metal articles.

A method of manufacturing a casing of a turbocharger includes: a steam treatment step of subjecting at least one of a turbine housing and a bearing housing to a steam treatment to form an oxide film on the at least one of the turbine housing and the bearing housing before assembling the turbine housing, the bearing housing and a compressor housing; and an assembling step of assembling the turbine housing, the bearing housing and the compressor housing.

A device for machining the edges of casting strands includes one machining tool each that can be brought into contact with a longitudinal edge of the casting strand, and at least one guide element for perpendicularly applying the machining tools to the longitudinal edges. Means are provided for moving the machining tools in parallel to the longitudinal edges of the casting strands, in order to modify the relative speed between the longitudinal edges and the machining tools.
