Gravity casting refers to the process of injecting molten metal into casting under the action of earth gravity, also known as gravity casting. The molten metal is injected into the hollow casting made of high temperature resistant material and condensed to obtain the desired shape, which is called casting. The products obtained are castings. Gravity casting is a popular manufacturing method in the process of casting production. Many manufacturers and consumers choose to use gravity casting.

Vacuum casting is vacuum sealing modeling. The principle is to use plastic film to seal sand box, vacuum pump to extract the inner air of the mold, to form the pressure difference inside and outside the mold, and to make the dry sand tight to form the required cavity. Compared with traditional sand casting, the biggest advantage of vacuum casting is that it does not use binder, which reduces the sand treatment work, and the labor quantity of molding and casting sand cleaning is greatly reduced,

Sand casting is a kind of casting, which uses sand as raw material. This practice is ancient, it is a kind of traditional ancient casting. Because of its good fluidity, filling and storage, high strength and good collapse, the coated sand is widely used in mass production of various types of cores with complex structure and high quality requirements. Our company mainly uses sand casting technology to produce cast iron flume blank.
