[0002] Sand casting is a casting method that uses sand as the main molding material to prepare the casting mold. Sand casting is the most traditional casting method. Due to the characteristics of sand casting itself (not limited by the shape, size, complexity and alloy type of parts, short production cycle and low cost, sand casting is still the most widely used casting method in casting production, especially for single or small batch castings. The basic process of traditional sand casting process has the following steps: sand matching, mold making, core making, molding, pouring, sand dropping, grinding, inspection and other steps. After pouring and waiting for the molten metal to solidify, use a hammer to remove the gate and shake off the sand of the casting, and then use a sand blasting machine for sand blasting, so that the surface of the casting will appear very clean. For castings with less strict requirements, the blanks can basically be shipped out of the factory after inspection. For some castings with special requirements or some castings that cannot meet the requirements, simple processing may be required.
