Formed in foundries via a process with the same name, die castings are solid metal parts and shapes. Die casting works fairly simply. First, manufacturers heat metal until it is molten. Then, they force this molten metal into hollow forming shapes called dies, molds or die molds. Dies are cut from a hard metal like steel. Closed dies, which are used most often, are made when manufacturers cut an original die into two separate blocks, tool them back together with their cavities aligned and then spray the joined pieces with a lubricant. (The lubricant makes parts removal easier and helps regulate temperature.)
While in the die, manufacturers apply a high pressure that helps force the metal to conform to the shape of the die. Once it has satisfactorily taken on said shape, manufacturers allow the metal to cool and harden. Sometimes, they follow the die casting process with secondary processes aimed at improve the quality of the casting in some way.
Typically, manufacturers perform die casting using one or more non-ferrous metals. Such metals include aluminum, bronze, copper, lead, magnesium, tin and zinc. While they can use steel as well, steel and steel alloys are usually reserved for the forge. Learn more about die castings.

The example about the mattress sizing page you mentioned in the last WBF can be a perfect example of new keywords and content, and broadening the funnel as well. I can only imagine the sale numbers if that was the site of a mattress selling company.
