two production methods of casting mold Modern casting mold production methods, including wet sand molding method, loss of mold casting two methods.

　　 1, wet sand molding method, suitable for most of the metal material, mass production of the modeling method, clay wet sand modeling is the most economical modeling method. Foundry plants equipped with the latest technology control device, it should be gradually done, with wet sand control technology can be repeated to get the best performance. These control devices include: sieving the separation of metal, the reuse of sand cooling, re-use of sand when mixing the correct amount of additives and so on.

　　 2, Lost Foam Casting, As the development of equipment and raw materials , the use of the ratio is expanding. Multi-directional filling point of work, filling sand (follow-up sand) real-time filling and other new technologies, so that casting quality, shape speed and lower cost. The advantages of Lost Foam Casting are: foam mold can be no slope or diagonal small, and sometimes can be used to make complex shapes can shape, the design is more casual.
