The epithet of precision casting is solid non-metallic non-metallic water pouring to the shape of the machine and the opposite of the smelting mold, and other castings after freezing constitutes our smelting goods. Smelting methods include Shazhu, special smelting, fine smelting, V method smelting, fine casting outside the fine smelting attributed to special smelting. Attributed to the interesting castings, die-casting is the smelting method of pressure smelting.
Forging more raw materials to force the external force, it is in the form of condensation deformation. He is filling the smelting mold with a solid non-metallic state at a low pressure. Smelting with fine smelting machine does not demand processing, or may require a large number of processing can be used.
