Lost foam casting is a precision casting method that uses EPS foam plastic patterns soluble in acid to form the prototype of the casting in ceramic molds, and then obtains the casting with the opposite shape by pouring metal liquid.
Its process characteristics include near-zero allowance, precise molding, reduced tooling costs, reduction or elimination of processing steps, increased labor productivity, reduced labor intensity for workers, and minimal environmental pollution. It has been widely used in industries such as automotive, tractors, internal combustion engines, ships, aviation, petroleum, and chemical engineering.
The origin of lost foam casting dates back to the late 19th century in Europe, initially used for the production of steel castings. However, with the continuous development of technology and the expansion of its application range, it began to be widely used in various industries for the production of various castings in the mid-20th century.
