The traditional production mode adopts a general forming pool, and in order to meet the production requirements of products with large diameter or length, the size of the forming pool is more than 1 cube (the length, the width and the depth are more than or equal to 1 meter). The utilization rate of raw materials is low, and slurry with the height of liquid level, which can completely immerse the die, is needed for forming each product. Once the liquid level drops below the die, the product is scrapped due to uneven thickness, and continuous feeding is needed to maintain the liquid level. The excess slurry after forming can only be discarded.

Along with the increase of shaping quantity, the concentration of thick liquids also can change in the shaping pond, and the density of former phase shaping article and later stage shaping product also can progressively reduce, finally brings the heat conductivity deviation of product and influences the heat preservation effect.
