In Zhuozhou City, Hebei Province, Dahezhuang Brick and Tile Factory uses a waxing, drying, and drying industry. The mold can save molding oil, and can also improve the quality of the billet. The 10,000-milligram molded blanks consume about 25kg of oil. After the wax is changed, the oil can be used completely. Only a few fine soil powders can be used to press out the good quality of the blank. The dry breakage rate of the tile made from the wax mould is generally 4%, and the first grade rate of the billet reaches 70%. The technical and economic effects of the wax pattern and other various tile-type tiles are shown in the following table.
