The present invention relates to a method of disintegrating a foundry mold comprising sand and a polyurethane binder. The present invention further relates to a method of disintegrating a foundry mold by contacting it with a composition comprising at least one carboxylic acid amide and at least one tyalkanolamine.

A roller casting method produces a spiral structure, in particular a spiral structure for use in electric machines. Molten metal is supplied between a first roller and a second roller miming opposite thereto, wherein the first roller has first teeth, and the second roller has second teeth, said first and/or second teeth having tooth flanks with cavities for receiving the supplied molten metal. The teeth are designed and aligned such that the cavity of at least one tooth is at least temporarily delimited by the surface of a tooth of the other roller when the rollers are rotating such that the supplied molten metal is molded between the teeth while cooling and is molded into a section of the spiral structure.

A method for producing a cast workpiece includes the following method steps: providing a mold having at least one mold core arranged in the mold; inserting a metal melt into the mold; waiting for a period of time until at least the outer contour of the metal melt has solidified and the workpiece has been formed from the metal melt; removing the workpiece from the mold; shattering the mold core, wherein this method step is carried out before the workpiece has entirely cooled down from the casting process. For shattering the mold core, a hammer head is applied on a defined energy transmission surface of the workpiece and the energy transmission surface is acted on, in particular hit on, by the hammer head.

The present invention relates to a hubless one-piece wheel comprising: a rim; and a disc integrally formed at the rim and formed by low-pressure casting, wherein the disc is a hubless type including a plurality of spokes and a space at the center of the rim. One side of said each spoke is integrally formed at the rim, and a lug hole is formed in the other side of said each spoke for coupling the wheel to a vehicle body. The plurality of spokes are radially arranged inside the rim, and each of the other sides of the spoke locates in the inner center portion of the rim being separated by the space.

Aspects of the disclosure generally relate to a casting mold for forming a cast part. The casting mold includes a casting shell having an internal surface bounding an interior, and a casting core positioned within the interior to define a cavity between the casting core and the casting shell, whereby the internal surface of the casting shell defines an outer surface of the cast part.

A method of manufacturing an aerodynamic element with an edge is provided. The method includes producing the aerodynamic element with an initial condition, cooling the aerodynamic element, generating a predefined number of data points sufficient to characterize contours of the edge and comparing the data points to a nominal condition to derive transformation parameters applicable to cutting toolpaths to adapt the cutting toolpaths to the initial condition.

The present disclosure relates to the technical field of trimming dies and specifically relates to a trimming die for a casting of a front steering knuckle in a double-wishbone suspension. The trimming die includes an upper roof, an intermediate plate, a movable plate, a base, springs, connecting columns, a pressing block connecting rod, a cutting edge, a pressing block, a casting, hold-down blocks, a first supporting block and second supporting blocks.

The present disclosure relates to a sub-frame cleaning and blow-drying device, comprising a rack, a water tank, a bottom lifting assembly, supporting assemblies, a top lifting assembly, a rotating assembly, an expanding and cleaning-off assembly and a blow-drying device. Expanding assemblies expand to be connected with vehicle body mounting holes, compressed air is blown into the vehicle body mounting holes by air outlets and is blown into a cavity of a sub-frame to clean off aluminum scraps and residual sand in the cavity of the sub-frame, the rotating assembly drives the expanding and cleaning-off assembly and the sub-frame to do rotation movement to perform secondary cleaning, so that the aluminum scraps and the sand remaining inside the cavity can be cleaned off, and the sub-frame cleaning and blow-drying device can be flexibly adjusted by a position adjusting assembly according to different types of sub-frames and is strong in universality.

A method of manufacturing a casting is provided and includes establishing desired dimensions of a nominal casting, executing a casting process to produce multiple actual castings with each of the multiple actual castings having respective dimensions that differ from each other and from the desired dimensions of the nominal casting and engaging one or more tools to adaptively machine, without rigidly-programmed toolpaths, each of the multiple actual castings to reduce the respective differences between the actual dimensions of each of the multiple actual castings and the desired dimensions.

A system for separating a part from a monolithic tree includes a camera positioned facing the tree and configured to identify a cut mark on a gate of the tree, the tree including a runner, the part connected to the runner with the gate, each of the runner, the gate, and the part including a cast material; and a robotic arm configured to manipulate at least one of an orientation and a position of the tree.
