Die Casters
Die casters form metal through a process in which molten metal is put under pressure and injected into a die. At the end of the process, the metal, kept just above its melting temperature, quickly solidifies into the shape of the die casting. Ejector pins remove the die cast part.
Die casters use materials such as zinc, aluminum, magnesium, tin, lead, and copper. Some die casters also have extra parts, such as removable slides and cores, to produce holes, threads and other desired shapes in the casting. Dies are either air- or water-cooled; the cooling of the die provides for quick cycling and is one of the factors in the high rate of production. It also gives a fine grain structure and superior strength and finish to the metal castings.
Die casters are useful for many reasons. First, they are efficient, economical, and offer a wide range of durable shapes and components. Little or no machining is required after a part is die cast, because the process provides very close tolerances for even complex shapes. Also, die casters are dimensionally stable and heat resistant with the ability to retain the strength of an alloy. Die casters are utilized for many uses, such as in the production of hardware and tools and in the automotive, construction, architectural, plumbing, and electronics industries.
