[0003] Casting methods can be divided into: ordinary sand casting, using sand as the mold material, also known as sand casting, sand casting, including wet sand molds, dry sand molds and chemically hardened sand molds. The advantage is that the cost is lower because the sand used in the mold can be reused; the disadvantage is that the mold production is time-consuming, the mold itself cannot be reused, and must be destroyed to obtain the finished product; metal mold casting, using metal with a higher melting point than the raw material to make the mold, which is subdivided into gravity casting, low-pressure casting and high-pressure casting. Due to the melting point of the mold, the metal that can be cast is also limited.
