Most of the defects on aluminum alloy die-casting molds do not occur when grooves are opened in the castings or when the enterprise analyzes mechanical processing.

Die casting molds are molds used for the production of die-casting parts, and their shapes can be determined. The production technology and process can to some extent determine the practicality of the industrial enterprise parts cast.

1. Melting process 1) Carbon equivalent. It should have a relatively high carbon equivalent, HT250, and up to 3.95; HT300， And up to 3.82; HT350， And 3.76.
