Casting machine equipment in a large proportion of liquid molding parts, machine tools, internal combustion engines, mining machinery, heavy machinery in liquid molding parts from 70% to 90% of the total weight; 50% to 70% in the car, tractor; accounting for 40% to 70% in the agricultural machinery. Liquid molding process can be so widely used, because it has the following advantages: (1) can be manufactured lumen rough shape very complex. Such as various cabinet, machine bed, cylinder block, cylinder head and so on. (2) process flexibility, wide adaptability. The size of the liquid molding parts virtually unlimited, its weight by a few grams to several hundred tons, and its wall thickness by about 0.5mm to 1m. The industry who can melt into liquid metal material can be used for liquid molding. For poor cast plastic streamer tank manufacturers, liquid molding is the only way to produce it blank or parts. (3) liquid-form lower cost. Direct use of waste liquid molding parts and chips, lower equipment costs. Meanwhile, the liquid molding pieces small allowance, saving metal. Many factors affect the quality of castings, the first is the casting of the design process. When the design, in addition to determining the casting geometry, size according to the working conditions and material properties of the metal, but also from the point of view must be cast alloys and casting characteristics to consider the design is reasonable, that is a significant size effect and solidification shrinkage , stress and other problems, in order to avoid or reduce segregation castings, deformation, cracking and other defects generate. The second to have a reasonable casting process. Casting structure that is based on the weight and size of the streamer trough, cast alloy and production conditions, select the appropriate sub-surface and shape, making the core method, a reasonable set of cast bars, cold iron, riser and pouring system. In order to ensure access to quality castings. The third is the casting quality of raw materials. Quality metal charge, refractories, fuel, flux, modifier and foundry sand, sand binder, paint and other materials, sub-standard, will make casting porosity, pinholes, slag, sticky sand and other defects, affecting the appearance quality of castings and internal quality, casting serious cause scrapped. The fourth is the process operation streamer tank, to develop a reasonable process rules to enhance the skills of the workers, so that technical rules properly implemented. Streamer trough price, streamer tank, Chen Hua Chen machinery provided by the China Machinery Equipment Co., Ltd. Qingdao. Qingdao Hua Chen Machinery Co., Ltd.
