A casting mold having at least one cavity for manufacturing at least one cast article, in which at least some areas of a casting surface of the casting mold delimiting the cavity have a surface texture. The surface texture has multiple elementary cells, wherein each elementary cell has a structure that projects and/or is recessed with respect to the casting surface and ends within the applicable elementary cell. In addition, a cast article produced by the casting mold is provided.

A process of forming a low cost, erosion, oxidation, and wear resistant composite liner or insert that can be installed into a shot chamber in a die casting machine is provided. The process utilizes a self-healing erosive wear resistant coating on a liner of refractory metal to serve as the working surfaces of a shot chamber. The refractory liner is bonded to a low cost material so that the liner can be made extremely thin. Such a composite liner is expected to have an improved service life for die casting of corrosive metals and alloys.

A method and apparatus for real-time in-mould marking of a moulded or cast form with an identifier in which a configurable marking module (1) with phase change actuators (23) in the form of a multi-layered printed circuit board assembly (1) with a vertical element (33) having a marker (21) is installed in a mould (2), (35), the marker (21) being remotely configurable by a controller to create a unique identifier which is applied to the form in the mould.

A process for producing an optical element, which may be suitable for use in an infrared camera with sharp surface features and low emissivity surfaces, including the steps of casting the element in the desired shape in a zinc alloy, deburring the zinc alloy element with a thermal deburring operation, and coating the deburred zinc alloy element with an electrocoating operation.

A casting mold for casting a piston for an internal combustion engine may include a mold body having a surface texture in a region corresponding to a subsequent internal surface of a piston skirt. The surface texture may be defined by a plurality of grooves. The plurality of grooves may have the following dimension: a depth of 0.2 mm<t<0.5 mm, a width of 0.02 mm<b<0.05 mm, and at least two groove walls which are inclined outwardly at 0<<10.

According to various embodiments, a dissimilar metal member according to various embodiments, comprises a first metallic material including a bonding portion, the bonding portion including a pattern formed by a laser; and a second metallic material bonded to the bonding portion of the first metallic material by die casting, wherein a portion of the second metallic material forming contact with the bonding portion of the first metallic material forms a reverse negative of the pattern.

A process of forming a low cost, erosion, oxidation, and wear resistant one-piece composite liner or insert that can be installed into a shot chamber in a die casting machine is provided. The process utilizes a thin inner layer of refractory metal to serve as the working surfaces of a shot chamber. The thin refractory layer is bonded metallurgically to a thick low cost material to form a one-piece liner thick enough to resist thermal distortion during die casting operation. A self-healing erosive wear resistant coating is applied on the working surface of the refractory metal layer. Such a one-piece composite liner is expected to have an improved service life for die casting of corrosive metals and alloys.

A method for the production of castings which are permanently provided with readable information. An identification element, which has an information surface, provided with information, and a casting surface which is assigned to the casting and also provided with information, is arranged on a casting mould surface assigned to a mould cavity of a casting mould so that the information surface is covered, while the casting surface is exposed in the mould cavity. A metal melt is poured into the mould, so that, during casting or solidification of the metal melt, a firmly bonded, form-fit or force-fit connection of the identification element to the casting is produced. The information on the casting surface is reproduced in the manner of a stamp on surface of the casting. The casting is then removed from the mould and fettled.
