Get MoreIn metalworking and jewellery making, casting is a process in which a liquid metal is somehow delivered into a mold (usually by a crucible) that contains a negative impression (i.e., a three-dimensional negative image) of the intended shape.The metal is poured into the mold through a hollow channel called a sprue.The metal and mold are then cooled, and the metal part (the casting) is extracted.
Get MoreAdditive manufacturing (AM) processes allow for the construction of parts directly from a digital drawing file without the retooling cost associated with casting and forging. Wire or powder is melted onto a substrate by a laser or electron beam and allowed to cool and solidify to form a fully dense geometry built up on a layer by layer basis.
