Specialized production of foundry industry has begun to take shape. It has now developed a number of distinctive professional casting manufacturer. These companies include: high compaction advanced system modeling + core + double-melting engine castings business; large quantities of mechanized production of brake drums, brake discs, exhaust pipes and other automotive castings plant; Resin Sand as the main machine, cabinet, wind power plants and other large castings; V method process as the main EPC foundry and factory; metal type or metal type cladding sand-based crankshaft, ball manufacturing plant; silica or silicic acid ethyl fat binder upscale lost wax precision casting; water glass as binder ordinary steel casting plant; centrifugal ball mills and centrifugal gray cast-iron pipe cast-iron pipe plant; non-ferrous alloy sand casting pressure (high / low / poor) casting plant and the like. Casting - Single metal smelting, manufacturing mold and molten metal is poured into the mold, after solidifying obtain a certain shape, size and properties of the metal parts forming process is to cast blank to meet certain requirements for metal melting and pouring liquid into mold inside, the cooling and solidification, to give clear a predetermined shape, size and performance of the process after the entire casting process. Rough casting due to the near-forming, and to achieve a small amount of free machining or processing purposes to reduce costs and to some extent reduce the production time. Casting is one of the basic technology of modern equipment manufacturing industry. There are special casting sand casting and 2 categories. Ordinary sand casting, the use of sand as a molding material, also known as sand casting streamers groove, foundry streamers groove repression, including wet sand, dry sand and chemical hardening sand three categories streamers grooving, but not all can be used for sand casting. Advantage of lower cost, because the use of the mold sand can be reused; drawback is time-consuming production mold, the mold itself can not be reused, must be destroyed after the finished product can be achieved. Towing tank, Chen Hua machinery, streamers groove mold provided by the China Machinery Equipment Co., Ltd. Qingdao Chen. Qingdao Chen Hua Machinery Co., Ltd.
