各种铸造工艺的区别及软件应用（The difference between various casting process and software application） A: process 1. casting can also be divided into gravity casting and pressure casting according to the pouring process of molten metal. Gravity casting is the process of pouring molten metal into the mold under the action of gravity of the earth, also called casting. The generalized gravity casting include sand casting, metal mold casting, investment casting, mud casting; metal type casting refers to narrow gravity casting. Pressure casting is the process of pouring molten metal into other molds under the influence of other external forces (without gravity). Generalized pressure casting, including die-casting machine pressure casting and vacuum casting, low pressure casting, centrifugal casting, etc., narrow pressure casting, special press casting machine metal mold pressure casting, referred to as die casting. Xudong precision casting factory engaged in sand mold and metal mold gravity casting. These kinds of casting process are the most commonly used and the lowest relative price in nonferrous metal casting at present. 2. sand casting is a traditional casting process using sand as the main molding material. Sand casting usually adopts gravity casting. When there are special requirements, low pressure casting and centrifugal casting can also be used. Sand casting wide adaptability, large and small, simple, complex parts, single and mass are used. Sand casting mould, formerly made of wood, as wood. Xudong precision casting factory in order to change the block deformation and easy to damage other ills, in addition to sand casting production of single, all to the higher dimensional accuracy, and long service life Aluminum Alloy mold or resin mold. Although the price has improved, but still more expensive than the die casting mold, in small quantities and large production, the price advantage is particularly prominent. In addition, the sand mold is more refractory than the metal mold,
