Die casting is a process for production of metal alloy parts. Die casting is usually done with metals with low melting temperatures, such as aluminum alloy, zinc alloy, and brass. In die casting molten alloy is injected into a steel mold under high pressure to form the metal parts. Finishing processes such as polishing, anodizing, and powder coating may be applied afterwards to improve surface appearance.
Relative to many other casting methods, such as sand casting, die casting forms cleaner, higher tolerance parts that require less post machining and have lower porosity. However, die casting can only be used with metals with a relatively low melting point.
When designing your die cast part abide by the following guidelines where possible:
