Background

The casting processes such as the lost foam casting process and the V method are all carried out by using dry sand, the temperature of the molding sand which is just opened and falls in the continuous production is usually up to more than 300-500 ℃, and the plastic film which is in contact with or close to the molding sand and the EPS mold 70 are softened and deformed about C during the molding. The molding sand used continuously was not rapidly cooled to 60' C or less, and the molding was no longer possible. Therefore, the problem of reducing the sand temperature becomes a main factor for restricting continuous, large-scale and large-scale production of the casting process. Three media are used for reducing the sand temperature, namely fluorine (and volatile substances such as diethyl ether), water and air. Fluorine and other refrigerants have the highest cooling efficiency, but a refrigeration compressor is required, so the cost is high.
