metal casting
Metal casting is the process of making a finished metal such as iron by pouring the molten metal into a mold and letting it cool and solidify. What metal casting mainly do is mold the metal into the shape of a great variety of things, with impossible for other ways or economically unfeasible to be done items. Precision mold-making, efficient melting systems, and advanced finishing techniques are all technological features of this process. Metal casting has become widespread in production, from automotive and aerospace to construction and healthcare, where durable, complex parts or assemblies are needed. It makes possible those designs which comply to practical requirements so large numbers can be produced economically: both the strength of tankers and their low cost.
