Dry sand casting differs from its green counterpart primarily in its use of dried molding sand. The molds are baked in an oven to harden the sand, creating a more rigid mold. This method reduces the moisture content and, in turn, the likelihood of defects like gas porosity.

Moreover, the choice of facing sand may vary depending on the type of metal being cast and the specific requirements of the casting process. Finding the optimal type and composition of facing sand involves ongoing research and development to ensure that it meets the evolving demands of the industry.

The primary advantage of cold chamber die casting is its versatility. It can accommodate a wider range of materials, making it a popular choice for industries that utilize aluminum and magnesium, especially in the automotive and aerospace sectors. Cold chamber die casting machines can also produce parts with excellent surface finishes and intricate geometries.

1. Investment Casting Also known as lost-wax casting, this method involves creating a wax model of the desired part, which is then encased in a ceramic material. Once the ceramic material hardens, the wax is melted away, leaving a precise mold. Molten metal is then poured into the mold, resulting in highly detailed and accurate components.
