How does die casting differ from other casting production methods?
A. On the one hand, die castings offer many of the qualities of gravity-cast parts: the rigidity, look and feel of solid metal; documented fatigue strength characteristics; excellent sound damping properties; inherent EMI shielding for electronic applications; and part serviceability and recyclability. Unique to the advanced die casting process, which employs high pressure and temperatures to cast the most intricate part details using premium quality steel dies, castings can be rapidly and consistently produced to close tolerances, often eliminating all machining. Sand castings require a new sand mold with each casting or gate of castings. The permanent mold gravity process uses iron or steel molds, but, like the sand process, is far slower and less precise than die casting. High-tech die casting can produce the highest quality surface finishes, as cast, and parts can also be designed with inherent bearing properties.
