[0002] A casting is an object made by a casting process, which is mainly formed by pouring molten metal into a pre-made mold, and then cooling and solidifying to form a part with a specific shape, size and performance. Castings can be made of different metals and alloy materials, including steel, iron, aluminum, copper, etc., and can have complex shapes and high-precision dimensions. They are usually used in the manufacturing industry to produce machine parts. When casting is completed, a surface cleaning device is required to clean the impurities and burrs on the surface of the casting.
