Lubricant compositions and methods of producing die-cast products by applying such a lubricant composition to a working surface of a die prior to casting a product from a molten metal injected into the die. The composition serves as lubricant between the die and resulting product, and contains at least one active component that reacts with an oxide of the metal to remove a layer of the oxide that forms on a surface of the melt during the die casting process.

A die-cast mold for die casting aluminum includes a first die having a first mold surface, a first multilayer coating disposed over the first mold surface, a second die having a second mold surface, and a second multilayer coating disposed over the second mold surface. The first multilayer coating includes a first base layer and the second multilayer coating includes a second base layer. The first die and the second die mate to form a mold cavity. Characteristically, the first base layer and the second base layer are each independently composed of a zirconium nitride or a zirconium carbide.

An additive manufacturing system includes a build platform, a particulate dispenser assembly configured to dispense or remove particulate to or from the build platform, and a plurality of print heads each having at least one binder jet. The binder jets are configured to dispense at least one binder in varying densities onto the particulate in multiple locations to consolidate the particulate to form the component with a variable binder density throughout. The system also includes a plurality of arms extending at least partially across the build platform and supporting the print heads and at least one actuator assembly configured to rotate the print heads and/or the build platform about a rotation axis and move at least one of the print heads and the build platform in a build direction perpendicular to the build platform as part of a helical build process for the component.

A foundry component for an apparatus for casting or handling a metal melt includes a metallic main body which is provided in a melt-contact surface region with an anticorrosion layer structure composed of one or more superposed layers. The anticorrosion layer structure has, as a sole layer or as one of a plurality of layers, a protective woven fabric body prefabricated as flexible woven fabric body from a woven fabric material which is casting temperature resistant or a nonwoven protective layer prefabricated as pliable nonwoven layer from a fiber nonwoven material or fiber paper material which is casting temperature resistant or a protective shaped body prefabricated as rigid shaped body from a material which is casting temperature resistant.
