The casting method can be divided into two categories, namely, the traditional casting method and the modern casting method. The traditional casting process is also called the sand casting process, and the sand is used as a molding material according to different compositions. The sand can be subdivided into a wet sand casting method (Green Sand Mold), a surface dry sand mold casting method (Dry Sand Mold), etc. The advantage of sand mold casting is lower cost because the sand used in the mold can be reused; The disadvantage is that the casting is time-consuming, the mold itself cannot be reused, and the finished product must be obtained after being destroyed.

Therefore, most of the sand molds will be broken by the manufacturer after the one-time use, and the state of the used sand mold will be changed after casting. The original fine sand will be burnt due to high temperature. It is in the form of a block, and contains impurities such as additive granules and metal granules. Therefore, in order to recycle and reuse it, the manufacturer will crush, cool, and re-use it after being filtered by a roller machine. The original process is recycled and reused. The machine has a large mechanical footprint and has heat dissipation due to its mechanical structure.
