Molding is a multistep process that will form a cast around the pattern using molding sand. In casting, a mold is contained in a frame called a flask. Green sand, or molding sand, is packed into the flask around the pattern. This is known as metal sand casting. Once the sand is packed tight, the pattern can be removed and the cast will remain.

Even surface finish: Using coal dust low ash in sand casting has proven to produce more even surfaces than Petrobond sand. This is because, with foundry coal dust, sand inclusion and expansion defects are eliminated. It produces whole, solid blocks such with no blow holes even when the crosssection of the cast object is analyzed.
