Intermediate frequency furnace casting method and production batch to adapt such as sand casting, mass production factories should be to create conditions for the advanced technology of modeling, core making method. Old shock or jolt squeeze moulding machine production line productivity is not high enough, high labor intensity of workers, large noise, does not meet the requirement of mass production should be gradually change.

Low pressure casting, die casting, centrifugal casting and other casting methods, because of the expensive equipment and tooling, so it is only suitable for mass production of intermediate frequency furnace.

Single piece and small batch produced by intermediate frequency furnace of heavy castings, manual modeling is an important method, manual modeling can adapt to a variety of complex requirements are flexible, does not require a lot of technology and equipment. Can be used in cast iron, cast steel and non-ferrous metal foundry industry has a core, small and medium sized castings efficient, high-volume production of tidal sand mold. Batch production or long-term production of stereotypes products using multi box modelling, split box modeling method is more appropriate, although mould, sand box, etc to start high investment, but can be compensated from saving form of working hours and improve the quality of the products.
