Problems solved by technology

[0002] Because the molding materials used in sand casting are cheap and easy to obtain, the casting mold is easy to manufacture, and it can adapt to the single-piece production, batch production and mass production of castings. It has been the basic process in casting production for a long time; sand casting has Sand mixing and sand sieving, among which sand sieving is mainly to remove impurities such as scrap iron, agglomerated sand and other things to keep the sand even and clean when the old sand is reused; at present, many small and medium-sized enterprises use manual sand sieving, This is not only inefficient, but also the screening effect is not good; therefore, a sand casting sand screening machine is needed
